Lin En

Power Progression

Background / History

Lin En came from the ancient 2K era and died suddenly after staying up gaming. The system brought him into the Warhammer universe because of his reckless willingness to fight for humanity and potentially create a better future for the setting. 82

He initially survived through evasion rather than combat. Pursued by Chaos Cultists, he used narrow cave passages, his smaller build, quick thinking, and Thirty Days to remain alive. He later discovered an Imperial corridor and escaped the underground region. 3 4 5 18

His first trait, Flashlight, initially seemed useless compared with the combat ability he wanted. It nevertheless became essential for navigating the caves. With Thirty Days preventing his death, he also survived repeated injuries and once broke through a cultist encirclement by attacking with a stone. 2 3 4 13

Lin En met Battle Sister Cecilia and Adeptus Mechanicus tech-priest Iron Hammer while stranded on Istvaan III. Although all three were initially suspicious of one another, Lin En shared food with Cecilia and gradually became her ally. Cecilia promised not to abandon him, while Lin En revealed his regenerative ability and helped the group survive. 9 11 12 14 16

Before approaching Cecilia, he observed her for several days to assess whether her mutated eyes indicated Chaos corruption. Their initial alliance paired her combat experience with his illumination, allowing them to search the caves together. When pursuit forced them to separate, he volunteered to draw the cultists away while she sought reinforcements. He subsequently spent twenty-eight days concealed near an underground water source, learning patrol patterns and developing a stable survival routine. 10 13 16 32 33

After witnessing Tyrennius’s death, Lin En suffered his first direct psychological shock from watching a companion die. Cecilia restrained him and ordered him to run, forcing him to confront the brutality of the setting. 50

The Blood Angels Fifth Company arrived before the remaining daemons could overwhelm the survivors. Lin En later learned that Tyrennius had already vouched for all three companions, requested official protection for Lin En and Iron Hammer, and sought a reassessment of Cecilia’s alien designation. The discovery deepened the emotional impact of Tyrennius’s sacrifice. 50 52

After his rescue, the Inquisition investigated his undocumented identity and unregistered psychic awakening. Lin En supplied a fabricated account of having served an unnamed Terran Tech-Priest before being abandoned on Istvaan III. Physical scans found no mutation or evidence of Tyranid infiltration, while Cecilia and Iron Hammer’s accounts broadly supported his description of his subsequent survival. 54

His fabricated background also claimed that his father had been a Rogue Trader who disappeared, possibly after an encounter with Aeldari pirates, leaving him without a family or surname. This account was an improvised explanation to investigators, not a confirmed description of his actual parents. 54

Lin En later joined the Baal Guard with Cecilia and Iron Hammer. Because he could not properly write in High or Low Gothic, he asked Cecilia to complete his enlistment form. He registered only Danger Sense and Tactical Rehearsal, hiding his more dangerous abilities from Imperial authorities. 58 59

On Mezoa, Lin En was appointed the regiment’s sole psyker and given the prestigious but largely symbolic title of Chief Psyker or Chief Librarian. During the offensive against the Greenskins, he used Tactical Rehearsal and Ballistic Calculation to seize command of the 0825th Regiment and direct highly accurate artillery strikes. 63 64 69 70

His support abilities transformed the battle. Emperor’s Gaze empowered Cecilia and other soldiers, while Group Healing and later mass buffs allowed Imperial forces to overwhelm the Orks with minimal casualties. The soldiers interpreted his powers as direct blessings from the Emperor. 69 70 71

The Inquisition investigated Lin En after the Pollia battle. Its agents found that soldiers exposed to his Golden Light were healthy, mentally sound, healed of wounds, and free of Chaos taint. The investigation shifted from suspicion toward the possibility that Lin En was a genuine Living Saint. 80

The Ultramarines then transferred Lin En to Macragge, where his role changed from mortal Guard psyker to Ultramarines Chaplain. His healing, morale enhancement, and battlefield blessings were judged more useful to the Chaplaincy than to the Librarius or Apothecarion. 83 98 99

During the journey, Captain Autolo questioned him about his battlefield halo and the Regent’s secret order before taking him into a private room. Lin En was subsequently confined and exposed to poison gas in an attempt to prevent him from reaching Macragge and helping stop Behemoth. He survived, warned the rescuing squad to contain the gas, and discovered that the captain had escaped; he identified the plot with the Alpha Legion. 87 88 89

At Hera Fortress, Calgar initially suggested companies with defensive assignments, but Lin En chose the Third Company and accepted its dangerous frontline role against the Tyranids. During the campaign, he recognized that Calgar might be isolated in the Cold Steel Mountains and alerted the First and Third Companies, requesting reinforcements for a rescue. 97 114

Lin En became closely attached to the Ultramarines’ Third Company. After the Battle of Prandium, all ten companies competed to recruit him, while Third Company insisted that he belonged with them. He ultimately retained his permanent posting there while receiving additional honors as a defender and advisor. 151 152 158 159

After a Greater Daemon’s attack injured his soul, Lin En recovered in the Librarium Healing Ward. Examinations found clean soul tearing rather than Chaos contamination, and psychic treatment restored his physical strength. Calgar classified him as a special-grade strategic asset, with protection comparable to Guilliman and Macragge’s Honour. His new Third Company quarters were converted from a room beside the command center and guarded around the clock. 145 149 156 158

While trapped in the Warp with the Third Company Captain, Lin En initially could not release his stored psychic energy through ordinary methods. After obtaining Dimensional Slash, he destroyed a Dark Apostle and his daemon warriors, but the disappearance of the enemy’s Soul Altar left the pair exposed in the open Warp. His passive absorption continued replenishing his energy as they sought shelter, until an approaching powerful presence prompted him to call for the Emperor’s help. 175 177 178 179

The Emperor later summoned Lin En to Terra. During their private meeting, Lin En acquired Psychic Paradox, making him immune to psychic attacks while preserving his own psychic abilities. He then began using the Emperor’s psychic excess as a source of power. 183 203 204

Lin En rejected the Emperor’s suggestion that he remain safely on Terra and passively accumulate rewards. Instead, he chose to continue participating in major events, believing that the system’s strongest rewards required genuine danger and meaningful story progression. 205

Before departing for Badab, Lin En received Custodes protection and a warship from Guilliman. He also gave Guilliman a Psychic Crystal recording of the Emperor calling the Regent humanity’s new savior; Guilliman subsequently sent him a Solar Fleet cruiser equipped with a new Warp engine as a return gift. 209

He accepted authority over troubled Chapters, beginning with the Lamenters, then later taking administrative control of the Mantis Warriors. Lin En argued that Chapters deceived into rebellion should be rehabilitated rather than destroyed if they remained loyal to the Emperor. 205 222 231 236

His rehabilitation policy did not deny the Lamenters’ responsibility for their actions. He considered a Penitent Crusade a just punishment for their actual, if deceived, treason and secured a suspension of their purge by offering to lead it himself. When told his existing appointment did not cover the Mantis Warriors, he contacted Guilliman for additional authority. 230

During the Bolomite campaign, Lin En supported the Lamenters and allied forces against Chaos, then used his psychic reserves to pull the entire forge world out of Tzeentch’s domain and return it to Imperial space. 247 248 249 250 251 252 253 254 255 256 257 258 259

Afterward, Lin En and Phoros returned to Terra with Lion El’Jonson. While the Lion went to meet the Emperor, they proceeded to the High Lords Council to report their mission and confront its members. 265

On Baal, Lin En visited Tyrennius’s coffin in the Heroes’ Mausoleum alone, asking his Custodes guards to wait outside. He used Matter Reassembly to create a Red Gladiolus as a memorial offering and made it an everlasting flower. He later returned with Cecilia and Iron Hammer, and the three recounted their lives and accomplishments to their deceased companion. 286 298

Lin En later reunited with Cecilia and Iron Hammer on Asphodex. He transferred them into his own sphere of command, placing Cecilia with the Lamenters and Iron Hammer as Fabricator-General of Bolomite. 287 301

He intercepted Hive Fleet Leviathan with unmanned spacecraft and the Battle Barges of the Lamenters, Flesh Tearers, and Blood Knights. Reports to Dante credited the three Chapters with blocking the Hive Fleet outside the Hades System while sustaining no obvious casualties and inflicting devastating losses. 288 291 292

While traveling toward Cretacia, Lin En fell into an unexplained, deathlike sleep and became trapped in an enormous nested illusion. He shattered one layer by unleashing all 240 points of his psychic power into a Psychic Storm, but his apparent escape into space and rescue by Phoros proved not to be the end of the trap. The apparent Cecilia and Iron Hammer attacked him, and their apparent deaths exposed further deception. Dante entered the illusion with the Bīgong Spear, and their combined assault finally shattered it. 301 302 305 306 307 309 310

During his subsequent recuperation at Bolomite’s completed Governor’s Palace, Cecilia and Iron Hammer restricted him to rest for at least seven days. Cecilia supervised reconstruction while Iron Hammer managed his immediate care; Phoros reported morning and evening, and the other Chapter commanders visited him. 319

After recovering, Lin En secretly followed his forces to Slaughterhouse III with Iron Hammer and helped rescue civilians from the Orks. On their return, Cecilia required both men to write self-criticism reports. As Bolomite’s factories, housing, defenses, and Lamenters Fortress expanded, Lin En used the back of his report to present a Blood Knights homeworld project, then obtained coordinates for an abandoned agricultural world from the system. 321 332 337

His later operations included the reclamation of Echo Star from the Warp, assistance to allied Battle Barges threatened by plague, and aerial combat against Angron. He subsequently developed a cheaper unmanned suicide-ship program for fighting Tyranids and deployed it against an incoming splinter of Hive Fleet Kraken. 350 364 365 373 377 389 395

For the Maelstrom expedition, Lin En left the Lamenters to defend Bolomite, Echo Star, and their civilian populations, reassuring Phoros that this assignment reflected his special trust in the Chapter. He took the Flesh Tearers and Blood Knights to investigate Nurgle’s attack on three Ultramarines successor Chapters. Cassius suspected that the plague mist trapping their Battle Barges was bait intended to draw Lin En into danger. 344

As the supply of unmanned Iron Boxes dwindled during the Kraken battle, Lin En authorized Phoros to lead the Lamenters into the attack. The system awarded him the Innumerable Enemy Kills achievement and a guaranteed-gold draw. He began the draw, but its result was not shown at that point. 378

Lin En’s control of Tyranids prompted another Inquisition investigation. The Inquisition acknowledged his authority as equal to its own and chose a cordial inquiry rather than arrest. Inquisitor Valens reviewed his record, inspected him with his cooperation, and witnessed his control of the swarm. Lin En then explained the necessity of severing the swarm’s connection to the Hive Consciousness while protected by the Emperor’s barrier and invited Valens to Bolomite to inspect the Purple Carapace Chapter. Valens’s report renewed radical inquisitorial interest in studying Lin En himself. 387 389 394 395 396

After learning from Sosila that the Kraken splinter fleet had fled Sotha upon detecting the Purple Carapace Chapter, Lin En pursued it toward the Eastern Fringe. Guilliman allowed him to continue independently, expressing confidence that he would not lose. Meanwhile, the Ecclesiarchy decided to describe his controlled Tyranids as the Emperor’s Swarm and to seek his opinion before formally canonizing him. 413

The Ecclesiarchy subsequently canonized Lin En as a Living Saint through distributed documents and a deliberately simple process rather than a formal ceremony. A week later, Chaplains across the Imperium announced the canonization and encouraged prayers for him. Lin En continued campaigning, directing the swarm to clear worlds while Rear Admiral Claude’s Imperial Navy forces followed to establish outposts and claim the planets. 415

When reinforcements were needed in the Solar System, Lin En departed Bolomite with three Chapters within twenty-four hours, leaving Cecilia in command of its human defenders. On the Night Goddess, he reassured Phoros that he would lead them to victory again. He returned confident in his combination of support, healing, direct offense, and Thirty Days, regarding Abaddon’s massed forces as a greater concern than Abaddon himself. 437 438

At the Solar System’s starport, Lin En reviewed the forces encircling the system, including Chaos, Dark Mechanicum, Aeldari, Necrons, T’au, and Orks. He disembarked with Phoros, Gabriel, and Sentoyor, met Dante, and was welcomed by Admiral Aurelian. The admiral explained that the reinforcing fleets would be organized, resupplied, and repaired before assignment to the outer defense line. 439

Appearance

Lin En is a youthful, physically unimposing human who initially appears smaller and weaker than the soldiers and superhuman warriors around him. He has fair, clean skin, neatly trimmed nails, and no signs of long-term manual labor. 5 12

• Appears younger than the people around him. Chapter 314 describes him as not yet nineteen, although Cecilia calls him twenty in an earlier scene and later chapters and Inquisition records also identify him as twenty. 50 314 377 389
• Initially wears Astra Militarum equipment and later black-and-gold Chaplain Power Armor. 5 99
• His Power Armor is a lightweight model adapted for mortal use. 99
• The Eye of True Sight leaves a faint golden light deep within his pupils. 148
• Often carries the Scepter of Truth and a mortal-compatible bolt weapon. 99
• Wears small, round sunglasses given to him by Cecilia, which he uses to project an exaggeratedly dignified appearance. 287

Personality

Lin En is humorous, argumentative, and prone to treating terrifying situations with irreverent commentary. He frequently quarrels with the system over card draws, ability descriptions, and withheld rewards, yet depends on it as his most reliable companion.

He is initially frightened and physically vulnerable, but adapts quickly. Rather than rejecting unwanted support abilities, he learns to recognize their strategic value. Danger Sense, Tactical Rehearsal, Ballistic Calculation, and Group Healing all become decisive because he applies them creatively.

Lin En is deeply protective of companions and ordinary soldiers. He chooses to remain with the Guard to protect Cecilia rather than immediately join the Adeptus Astartes, and he repeatedly risks himself to reduce casualties. 28 64 68 76

Despite his growing political power, Lin En remains uncomfortable with praise and insists that saving lives is simply his duty. 151

He is also increasingly ambitious. Lin En seeks authority not solely for status, but so he can shield his allies from the Inquisition and reform institutions he considers corrupt. 60 85 301

His compassion coexists with a concern for justice and accountability. He distinguishes between protecting deceived loyalists from excessive punishment and excusing their crimes altogether; his proposed Penitent Crusade for the Lamenters reflects that distinction. 230

Tyrennius’s sacrifice remains a lasting emotional reference point. Lin En dislikes discussing his death but tells Dante about him so that the Chapter Master will remember an otherwise obscure warrior. By the Baal campaign, he explicitly measures his growth against his earlier inability to protect Tyrennius and resolves not to repeat that tragedy. 276 284

His lightheartedness does not mean that he is emotionally invulnerable. Cecilia recognizes his return to joking after Tyrennius’s death as a sign that he has begun recovering from his first loss of a companion. His affectionate, tearful reunion with her on Asphodex contrasts sharply with the commanding image familiar to his subordinate Chapter Masters. 58 287

Although he distrusts inquisitorial institutions, he can cooperate readily with individual investigators. He willingly submits to Valens’s later inspection and tells him not to make procedural duties difficult for himself. Valens regards his lack of arrogance despite enormous power as unusually sincere. 389 394

Even formal canonization does not displace his irreverent practicality: he puts away the documents and asks Phoros to compile the Living Saint benefits he has not received so that he can request them later. His swarm-led campaigns nevertheless make his concern for human casualties unmistakable to Rear Admiral Claude, who contrasts their success with the enormous losses of previous wars. 415

By his return to the Solar System, Lin En regards himself as an all-round battlefield asset capable of support, offense, and healing. His confidence rests on the combination of his abilities rather than a belief that enemy numbers are irrelevant; he dismisses Abaddon personally while taking the scale of the invading armies seriously. 438 439

Abilities & Skills

Trait-Drawing System

Lin En possesses a system that grants traits through periodic card draws and achievement rewards.

• Regular draws become available after a fifteen-day cooldown. 64 94 246
• Major achievements can grant additional draws, sometimes guaranteeing gold rarity or higher. 65 66 203 312
• The system can register story nodes and kill achievements.
• Lin En believes the system’s strongest rewards appear when he actively participates in dangerous events rather than remaining in safety. 205
• The system has a sarcastic, evasive personality and repeatedly withholds or delays rewards before conceding them. 33 64 65 66
• His two active trait slots can fuse effects rather than merely activate two abilities independently. Passive traits such as Danger Sense and the permanent enhancement Eye of True Sight do not occupy those slots. 69 76 148
• Sacrificial enhancement can be performed when needed rather than immediately upon becoming available. Lin En is reluctant to sacrifice useful traits and later judges that recreating the full capabilities of the Men of Iron through Machine Spirit Resonance would require more enhancement than he can reasonably afford. 82 377
• System skills are not universally constrained by his stored psychic power, although abilities such as Group Healing scale with his psychic strength. This initially allows him to use support traits despite lacking native psychic energy. 71 116
• His cumulative kill count surpasses one hundred million after the Defense of Baal, granting the Numbered in the Hundreds of Millions achievement and the draw that produces Psychic Overload. 312
• He later completes Innumerable Enemy Kills during the Kraken engagement and begins another guaranteed-gold draw; its result is not revealed in that scene. 378

Early Survival Traits

Lin En’s earliest traits keep him alive despite his limited combat strength.

• Flashlight creates a controllable orb of moderate white light, illuminating roughly three meters for up to eight hours. Its description states that it cannot be used as a weapon, although Cecilia recognizes its practical value for navigation and briefly dazzling pursuers. 2 13
• Thirty Days prevents death during the first thirty days of fighting an enemy and enables recovery even from otherwise catastrophic injuries. Lin En considers whether changing opponents or reengaging an enemy could renew the effect, but the system does not confirm his proposed loopholes. 3 4 48
• Danger Sense is continuously active, detects hostility within 300 meters, and scales its warning with the strength of hostile intent. It can alert him while sleeping but does not identify a traitor who bears him no ill will. 18 29 148
• Stamina Enhancement increases stamina, endurance, and carrying capacity by 50%, but does not give him Astartes-level strength; he remains unable to cut through an Ork’s arm with an ordinary sword. 23 25
• Temporary Shield provides three seconds of protection against gunfire and psychic attacks and can also be used to intercept blows aimed at an ally. 28 177
• By combining Thirty Days with Group Healing, he can extend its survival protection to companions within his aura. 76 173 178
• Thirty Days does not itself prevent psychic restraint, making Psychic Paradox preferable against an opponent such as Magnus when freedom of action is essential. 250
• By the Solar System deployment, he is prepared to use Thirty Days openly and envisages combining mass immortality for armored warriors with Psychic Storm. This is his stated battle plan rather than a newly demonstrated enhancement to the trait. 437 438

Tactical Analysis

Lin En’s strategic abilities allow him to command forces far beyond his formal experience.

• Tactical Rehearsal simulates the battlefield and predicts enemy actions. 33
• Ballistic Calculation predicts projectile trajectories and impact points. 64
• Together, the abilities allow Lin En to:
  • Direct artillery without hitting allied troops.
  • Detect flanking attacks and enemy traps.
  • Predict feints, retreats, and ambushes.
  • Coordinate large formations in real time. 69 70
• His supernatural analysis compensates for his limited formal military training. 33 69
• Precise Throw provides exceptional accuracy with thrown objects, demonstrated by landing a pen in a distant holder across a ship’s bridge. 345

Emperor’s Gaze

Emperor’s Gaze is a gold-grade single-target aura that affects loyalists and traitors differently.

• Grants a loyalist a 100% increase to all attributes for thirty minutes.
• Suppresses a traitor’s attributes by 100% for thirty minutes.
• Can empower soldiers, Astartes, and Primarchs.
• Turned Cecilia into a dominant frontline fighter and greatly amplified the Lion King against Magnus. 66 69 257
• Can be fused with Group Healing to distribute its effects across a large group. 76
• Activates instantly and requires no upkeep after application. 132

Group Healing

Group Healing is Lin En’s principal mass-support ability.

• Heals wounds and restores stamina.
• Strengthens wills damaged by exhaustion or Chaos influence.
• Initially remains at a minimum range of one hundred meters because Lin En has no native psychic power. Psychic Absorption gives him a means to overcome that restriction. 116
• Can cover formations, as demonstrated during the Arctic Fortress deployment, and eventually battlefields several kilometers wide. 107 132
• Can serve as a platform for fusing other traits.
• When combined with Emperor’s Gaze and Psychic Paradox, it can grant large groups both physical enhancement and psychic immunity. 76 253
• Reaches a radius of nine kilometers during the Leviathan campaign, allowing the Night Goddess to carry an eighteen-kilometer-wide support zone through the fleet. 292
• Can transmit Immortal Will to the Lamenters, strengthening their resolve against mental interference. 254
• Its coverage remains spatially limited: sections of long Battle Barges extending beyond the aura can still suffer plague exposure and require subsequent attention. 350

Purification and Holy Light

Lin En’s Holy Light abilities counter Chaos corruption.

• Purification Aura removes Chaos Corruption from others, with success affected by the difference in strength between Lin En and the target. 65
• Weapon Enchantment gives weapons golden Holy Light and greatly increases their damage against daemons. 43 132
• The original enchantment applies to one melee or ranged weapon, grants 200% additional damage against Chaos targets, lasts thirty minutes, and has a one-hour cooldown. 42
• His empowered weapons can erase daemons permanently rather than merely banishing them to the Warp. 133
• He can purify Chaos Spawn and restore corrupted flesh to a human form. 43
• Purifying powerful figures may attract the attention of the Chaos Gods. 65
• Purification Crystals associated with his work earn the gratitude of Blood Angels successor Chapter Masters, who also credit him with saving the Flesh Tearers and Blood Knights. 285

Psychic Defense and Absorption

Lin En’s psychic abilities make him an exceptional counter to Warp-based enemies.

• Psychic Paradox nullifies psychic attacks while allowing Lin En to use psychic powers himself. 203
• Psychic Absorption converts 30% of incoming psychic attacks into usable psychic energy. It is first acquired during the Macragge campaign. 116 204 214
• Psychic Paradox protects him from the soul damage that would otherwise result from excessive psychic absorption. 204
• He has absorbed psychic attacks from Drukhari and endured massive assaults from Magnus and Tzeentchian sorcerers. 214 253
• His psychic reserves reached approximately 80 before being limited by his Psychic Pool. 204
• Psychic Absorption also draws energy continuously from the Warp itself while he is immersed in it. 179
• Absorption has no stated total intake limit, but his Psychic Pool limits the amount he can retain at one time; excess energy dissipates harmlessly rather than becoming available for later use. 204
• During the reclamation of Bolomite, his eighty-point reserve is identified as Alpha-plus. Absorbing energy while releasing it allows his total output to exceed his instantaneous storage capacity. 259
• Psychic Limit, a rainbow-grade trait, later raises his psychic power to 240 and enables his nine-kilometer aura radius. 295
• His reserves later reach 240 points, which he releases at maximum output against the Dark Illusion. 306
• Psychic Perception detects psychic fluctuations within one hundred meters and is used to maintain awareness while apparently drifting in space. 126 307

Lin En’s initial lack of native psychic anatomy is distinct from a shortage of stored energy. As a non-native of the setting, he begins without a Warp projection; even after absorbing power, he lacks the genetically derived Psychic Circuit required for ordinary psychic release. Meditation, gestures, imagined energy channels, and verbal commands all fail during his struggle beside the Third Company Captain, before he gains a usable offensive technique. 116 177 178

Eye of True Sight

Eye of True Sight is a permanent enhancement to Lin En’s eyes, functioning continuously without activation or use of an active trait slot. 148

• Sees through disguises and illusions.
• Detects possession and soul-level Chaos corruption.
• Can expose hidden traitors even when they do not appear hostile.
• Complements Danger Sense and Purification Aura by covering deception, hostility, and corruption as separate threats. 147 148
• Its stated effect has no upper limit based on the target’s power. 147

Machine Spirit Resonance

Machine Spirit Resonance allows Lin En to awaken and control machine intelligence.

• Can operate ships without human crews.
• Enables vehicles to maneuver with the precision of veteran pilots.
• Controlled vessels can ram enemies, evade fire, and self-destruct tactically. 94 104
• Initially controls up to 100 ships.
• After Lin En sacrifices Immortal Body, the limit increases to 200 ships. 104
• Its effects resemble a limited form of Abominable Intelligence.
• Allows suicide ships to dispense with crew accommodations, portholes, and control consoles. Lin En approves crude iron-box designs estimated to cost approximately 70% less than the standard version. 373
• He uses unmanned suicide craft against a splinter of Hive Fleet Kraken, choosing detonation angles for maximum damage. 377
• His relationship with the Machine Spirit of Macragge’s Honour extends beyond command: she asks him to remain aboard and encourages his continued service to the Imperium when he leaves. 194

Matter Reassembly

Matter Reassembly allows Lin En to generate or reconstruct matter.

• Changes matter’s physical and chemical form.
• Requires one to six hours of uninterrupted casting.
• Cannot be used during combat. 82
• Lin En later experiments with creating biological matter by mentally arranging cells and their components. 286
• Creating new matter requires an understanding of its composition; his first biological construction draws on his remembered knowledge of plant-cell structures. 286
• He creates a Red Gladiolus for Tyrennius’s coffin and makes it an everlasting flower, still vividly blooming on a later visit and expected to remain so for several years. 286 298
• He considers using it to restore Cecilia’s mutated eyes but withholds the attempt because revealing the ability would make both of them targets. 85
• Its description leads him to speculate about recreating a body for the Emperor; this is a contemplated application rather than a demonstrated achievement. 82

Dimensional Slash

Dimensional Slash is Lin En’s direct combat technique.

• Cuts through dimensional or physical obstructions.
• Destroys a Dark Apostle and his daemon warriors in a single attack during Lin En’s entrapment in the Warp. 179
• The system warns that using a rift as an escape route in the Warp could lead somewhere even more dangerous, including another Warp layer, a Chaos God’s territory, or a battlefield in another time. Lin En therefore declines to use a random opening as an exit. 178
• Failed against an illusion with no genuine space to cut. 306
• Later allows him to open a collapsed mine entrance and rescue tens of thousands of civilians. 332
• Has a limited range, forcing him toward the front line when he uses it against Tyranid vessels. 292
• Can be combined with Psychic Storm into an attack carrying dimensional blade-light within a golden hurricane. 310
• Wounds Angron but cannot independently overcome his rapid regeneration; repeated attacks on the same location deepen the damage before it closes. 364

Psychic Storm and Flight

Lin En eventually develops direct psychic offense in addition to his support traits.

• Psychic Storm is a gold-grade trait drawn after Psychic Limit has raised his power to 240. Its strength scales with psychic power, and its description presents its peak as capable of overcoming any defense. 295
• Psychic Storm creates a destructive golden storm around or ahead of him; releasing his full 240-point reserve shatters a layer of the Dark Illusion. 306
• Can operate alongside Dimensional Slash in a coordinated assault. 310
• Psychic flight lets him remain outside Angron’s immediate melee reach while attacking from above. 364 365
• His aerial tactics keep Angron away from the Ultramarines and lure him through Khorne’s own troops, causing substantial friendly destruction within the enemy army. 364 365
• Neither of his two principal offensive techniques proves sufficient to seriously defeat Angron in the described engagement. 364
• Angron attempts to counter the aerial attacks by throwing rocks, armor fragments, Berserkers, and daemon engines, but does negligible damage to Lin En during the engagement. 364 365

Warp Anchor

Warp Anchor is a gold-grade trait obtained through Lin En’s ten-million-kill achievement reward.

• Creates a permanent passage to a location in the Warp.
• Lin En retains it rather than sacrificing it.
• He envisages using it to let the Emperor confront a Chaos God within that god’s own domain, but this remains a future possibility. 126

Psychic Overload and Immortal Will

These traits provide Lin En with emergency protection and temporary escalation.

• Psychic Overload raises his psychic power by one full tier for thirty seconds once per day. 312
• Its description states no upper tier limit. Lin En interprets its current effect as a temporary rise from the human limit to Demigod level, comparable to a brief opportunity to use a Magnus-level Psychic Storm; this is his assessment of its potential rather than a demonstrated activation in that scene. 312
• Immortal Will protects his resolve against mental and spiritual attacks for thirty minutes, including Tzeentch’s influence. 253
• Immortal Will can be distributed through his Golden Light to reinforce the Lamenters’ collective fighting spirit. 254

Tyranid Control

Lin En demonstrates the ability to take control of a Tyranid swarm.

• Explains that the swarm’s connection to the Hive Consciousness must first be severed.
• Attributes his safe control to a protective barrier of the Emperor’s power.
• Warns that ordinary humans should not attempt the method without comparable protection. 394 395
• Associates the project with the Purple Carapace Chapter and invites Valens to inspect it. 395
• Inquisition discussions identify Lin En as irreplaceable to this approach because other investigators lack his protective barrier. 396
• A Kraken splinter fleet retreats from Sotha after detecting the Purple Carapace Chapter, prompting Lin En to pursue it toward the Eastern Fringe. 413
• The Ecclesiarchy adopts Emperor’s Swarm as the religious description for the Tyranids under his command. 413
• He directs the swarm to clear hostile worlds while human naval forces follow to occupy them, reducing the need to expend human troops in the initial planetary battles. Rear Admiral Claude witnesses the swarm destroy a Greenskin-held world before ordering an Imperial landing. 415

Equipment / Weapons / Items

• Chaplain Power Armor — Lightweight black-and-gold armor adapted for Lin En’s mortal body. 99
• Scepter of Truth — Chaplain weapon issued with his armor. 99
• Mortal-compatible bolt weapon — Issued instead of the larger Astartes bolt pistol. 99
• Psychic staff — Issued when Lin En was appointed Chief Librarian. 64
• Master-crafted bolt pistol — Part of his initial psyker equipment allocation. 64
• Psychic restraint headband and breastplate — A roughly fifty-pound restraint set that Lin En avoided wearing by pretending to be physically frail. 64
• Power Armor life-support systems — Sustain him during his apparent escape into space within the nested Dark Illusion. 306 307 309 310
• Round sunglasses — A gift from Cecilia and one of Lin En’s favorite personal possessions. 287
• Emperor’s Sword copies — Holy Light-enhanced weapons capable of permanently erasing daemons and Rubricae remnants. 133 247 258
• Psychic Crystals — Can contain recordings; Lin En gives Guilliman one holding the Emperor’s speech about humanity’s new savior. 209 214
• Purification Crystals — Supplied to Blood Angels successor Chapters and praised by their Chapter Masters. 285

Relationships

• Cecilia — Battle Sister, adoptive older-sister figure, and one of Lin En’s closest allies. He prioritizes protecting her, later brings her under his command, and considers restoring her mutated eyes. She continues treating him affectionately as a child despite his rank and disciplines him after his unauthorized expedition to Slaughterhouse III. During his recuperation she oversees Bolomite’s reconstruction, and he later leaves her to command its human defenders while he reinforces the Solar System. 12 64 85 287 301 319 321 337 437
• Iron Hammer — Adeptus Mechanicus tech-priest and close friend. He provides Lin En with energy bars, equipment, technical support, and constant companionship. He accompanies Lin En’s secret expedition and later oversees the production and redesign of unmanned suicide ships. 28 43 58 287 321 373

• Roboute Guilliman — Lord Regent and political ally. Guilliman transfers Lin En to the Ultramarines, entrusts him with strategic responsibilities, and approves his request to control the Mantis Warriors. He provides warships, arranges Lion El’Jonson’s reinforcement against Magnus, and emphasizes that Lin En’s survival takes priority even over Baal. Later, he permits Lin En’s pursuit of Kraken toward the Eastern Fringe, confident in his ability to win. 83 183 209 231 250 276 413
• Phoros — Lamenters Chapter Master and subordinate commander. He becomes deeply loyal to Lin En and repeatedly risks himself to protect him. During Lin En’s deathlike sleep, he prays for his safe return and accepts that Terra may need to intervene even if it means losing Lin En’s presence with the Chapter. He accompanies Lin En to the Solar System, where Lin En reassures him that they will achieve victory again. 236 259 302 307 437 439

Story Role / Major Arcs

Survival on Istvaan III

Lin En begins as a physically weak outsider who survives Chaos pursuit through evasion, regeneration, and environmental ingenuity. His escape establishes his preference for preparation and support over direct confrontation. 5 18 28

His first two traits, Flashlight and Thirty Days, provide illumination and forced survival rather than the offensive power he wants. His alliance with Cecilia combines those advantages with her combat skill, and his willingness to draw away pursuers establishes his protective attachment to her. 2 3 13 16

Tyrennius’s death forces him to confront the cost of survival through another person’s sacrifice. The Blood Angels Fifth Company rescues the remaining group, and Tyrennius’s prior request for their official protection helps secure their return to the Imperium. 50 52

Mezoa and the Rise of the Chief Librarian

After joining the Guard, Lin En becomes the 0825th Regiment’s only psyker. He transforms from a symbolic Chief Librarian into the regiment’s decisive battlefield commander by combining Tactical Rehearsal, Ballistic Calculation, and Emperor’s Gaze. 63 64 65 66 67 68 69 70 71

The Ultramarines and Living Saint Investigation

The Inquisition’s investigation confirms that Lin En’s blessings heal rather than corrupt their recipients. The Ultramarines then recruit him, assigning him to the Third Company’s Chaplaincy. 80 83 98 99

His growing strategic importance also attracts hostile attention before he reaches Macragge. An attempt to confine and poison him fails, and he emerges determined to pursue the escaped infiltrator responsible. 87 88 89

Prandium and Ultramarines Recognition

Lin En’s battlefield support changes the outcome of the Prandium campaign. His healing, empowerment, and Holy Light blessings earn him the loyalty of the Ultramarines, whose companies compete to serve alongside him. 132 151 152

The campaign also leaves him recovering from soul injuries in the Librarium. His clean recovery reinforces confidence in him, while Calgar’s special-grade strategic-asset designation institutionalizes the Chapter’s commitment to his protection. 145 149 156 158

Terra and the Emperor

After being summoned to Terra, Lin En meets the Emperor and gains Psychic Paradox. The meeting also deepens the Emperor’s interest in Lin En as a possible solution to the Imperium’s conflict between humanity, godhood, and the Warp. 183 203 204 205

His arrival carries a personal shock as well: the gray, exhausted Throneworld is almost unrecognizable as the blue-green Earth he remembers. 196

Chapter Rehabilitation

Lin En accepts command or administrative authority over Chapters condemned or distrusted by Imperial institutions. He seeks to protect and rehabilitate the Lamenters, Flesh Tearers, Blood Knights, and Mantis Warriors rather than abandon them to the Inquisition. 205 222 231 236

He frames rehabilitation as fair punishment and restored service rather than immunity from judgment. His offer to lead the Lamenters on a Penitent Crusade suspends their purge, while his direct appeal to Guilliman extends his authority to the Mantis Warriors. 230 231

Bolomite and the War against Tzeentch

Lin En becomes a planet-scale force, supporting Imperial armies against Tzeentchian forces and dragging Bolomite out of the Warp. His role expands from battlefield support to the reclamation of worlds. 247 248 249 250 251 252 253 254 255 256 257 258 259

Baal and the Reunion with Cecilia

Lin En returns to Asphodex, reunites with Cecilia and Iron Hammer, and chooses to intercept Hive Fleet Leviathan in deep space rather than remain in a defensive position. 287 288

His fleet blocks the Tyranids outside the Hades System with minimal apparent losses among the three successor Chapters. His expanded healing aura, unmanned vessels, and direct attacks let him respond to threatened sections of the battle line. 291 292

The campaign is also framed by his remembrance of Tyrennius. He visits the Heroes’ Mausoleum, creates an everlasting flower for the coffin, and later returns with his two oldest companions to tell Tyrennius how their lives have changed. 286 298

The Dark Illusion

An unknown enemy traps Lin En in a powerful nested illusion that imitates familiar places and people. His allies find his body alive but unresponsive and contact Terra for help. Within the trap, deceptive scenes exploit his attachments to his parents, Cecilia, Iron Hammer, and Phoros. 301 302 305 307

Lin En’s first massive Psychic Storm destroys one layer but leads into an apparent space rescue that is itself part of the deception. Dante enters with the Bīgong Spear, and the two coordinate the spear’s attack with Dimensional Slash and Psychic Storm to shatter the trap. Lin En remains wary that another illusion may follow and is exhausted afterward despite the short time elapsed outside. 306 307 309 310 314

His allies’ insistence on protecting him continues after the immediate danger passes. At Bolomite, Cecilia and Iron Hammer enforce a seven-day convalescence while the Chapter commanders visit and report to him, temporarily reducing him to what Iron Hammer calls their mascot. 319

Slaughterhouse III

After recovering, Lin En secretly follows the fleet toward Slaughterhouse III with Iron Hammer. He supports Phoros’s forces through orbital bombardment and later uses Dimensional Slash to rescue tens of thousands of civilians trapped in a collapsed mine. 321 323 324 332

He supplies the three Chapters with weapons, medical equipment, and Stasis Fields and jokingly threatens to place severely wounded warriors in customized Dreadnoughts. His unauthorized departure angers Cecilia, who later requires him and Iron Hammer to write self-criticism reports. 321 337

Bolomite’s Expansion and Echo Star

Bolomite grows into a developed base with expanded warehouses, factories, residential districts, defenses, and a completed Lamenters Fortress. Lin En proposes acquiring an agricultural world for the Blood Knights, receives coordinates from the system, and is later credited with bringing Echo Star out of the Warp. 337 389 395

His later reception of Valens highlights Bolomite’s unusual peace and order: the inquisitor is astonished by its residential district and stays in the Governor’s Palace during his visit. 395

Angron and the Khorne Army

Lin En fights Angron from the air, using repeated Dimensional Slashes and Psychic Storms while healing the loyalist battlefield. Unable to defeat the Daemon Primarch’s regeneration directly, he instead diverts him away from the Ultramarines and through Khorne’s forces, turning Angron’s rampage against his own army. 364 365

Kraken and the Suicide-Ship Program

Lin En and Iron Hammer develop stripped-down unmanned ships for anti-Tyranid warfare. He approves inexpensive iron-box craft built by workers eager to serve him, then uses suicide drones against a splinter of Hive Fleet Kraken. The campaign demonstrates both the military utility and finite control capacity of Machine Spirit Resonance. 373 377

When the Iron Boxes are nearly exhausted, he permits Phoros and the Lamenters to lead a direct attack. The engagement also completes his Innumerable Enemy Kills achievement and triggers another guaranteed-gold draw. 378

Tyranid Control and the Inquisition

Lin En’s unprecedented control of Tyranids forces the Inquisition to balance doctrinal suspicion against his authority and proven service. Its leadership recognizes his standing as equal to the Inquisition and sends Valens to investigate without arrests. 387 389

Lin En cooperates with inspection, demonstrates swarm control, and explains the Emperor’s barrier that protects him from the Hive Consciousness. Valens reports the discovery from Bolomite, prompting radicals to debate how to study Lin En and his Purple Carapace Chapter without seizing him. 394 395 396

Canonization and the Emperor’s Swarm

After the Kraken splinter fleet flees from Sotha, Lin En pursues it toward the Eastern Fringe with Phoros and his other forces. Guilliman’s decision to let him operate independently reflects confidence in his ability, while the Ecclesiarchy begins resolving how to present his Tyranid command to the faithful. Its chosen description, the Emperor’s Swarm, frames the formerly alien threat as an instrument of Imperial victory. 413

Lin En’s formal canonization proceeds without an elaborate ceremony. Documents are distributed, and a week later Chaplains announce his sainthood across the Imperium. He treats the recognition pragmatically while continuing to lead the swarm from world to world. 415

Rear Admiral Claude’s navy follows the swarm to occupy cleared planets. Claude’s reflection on the lives consumed by earlier wars emphasizes the significance of Lin En’s method: hostile forces can be defeated without requiring human troops to bear the initial cost of each planetary assault. 415

Return to the Solar System

Lin En mobilizes three Chapters and departs Bolomite within twenty-four hours, trusting Cecilia and the planet’s strengthened defenses to protect the home base. He reassures Phoros that he will lead them to another victory and is prepared to employ Thirty Days openly. 437

During the return, he assesses himself as a mobile defensive anchor combining support, offense, and healing. His intended answer to Abaddon’s armies is an empowered, temporarily immortal armored force supported by Psychic Storm. 438

At the Solar System’s starport, he confronts the scale of a coalition containing Chaos, Dark Mechanicum, Aeldari, Necron, T’au, and Ork forces. Admiral Aurelian welcomes him and Dante and explains that the incoming fleets must be organized and supplied before taking their places on the outer defense line. 439
