Chapter Summaries

Plot points and events

• Lin En draws a Gold-grade trait, “No-Fly,” which prevents all living creatures from flying within its domain. Its description echoes Abaddon’s famous line, “Only angels deserve to fly,” and Lin En suspects the trait could also ground flying vehicles.
• Lin En questions the system about the unusually generous draw. It insists he earned the three Gold traits himself, making his suspicion grow.
• A shout of “Daemon Prince!” interrupts him. Angron, a gigantic, winged Daemon Prince of Khorne, approaches the battlefield at extraordinary speed.
• Lin En realizes the system may have given him No-Fly specifically because Angron was coming.
• The chapter recounts Angron’s tragic past: enslaved on Nuceria, fitted with the Butcher’s Nails, and left bereft of his gladiator companions when the Emperor teleported him away from their doomed uprising. Angron’s hatred and suffering helped turn him into a brutal servant of Khorne.
• The chapter ends with Lin En facing the incoming Angron.

Character developments and interactions

• Lin En moves from excitement over a powerful trait to suspicion that the system is manipulating events. He urgently recognizes the danger Angron poses.
• The system denies having intervened, but its timing makes Lin En doubt its honesty.
• Angron is presented both as a terrifying battlefield threat and a tragic figure whose slavery, the Butcher’s Nails, and the Emperor’s abandonment shaped his descent into rage.
• Lin En’s reflection on Abaddon connects the trait’s wording to the irony of a famous anti-daemon sentiment later associated with a Chaos warlord.

Significant themes

• Tragedy and responsibility: Angron’s past explains his rage without erasing the immense harm he has caused.
• The cost of abandonment: The Emperor’s rescue of Angron, while leaving his companions to die, becomes a defining betrayal.
• Fate and manipulation: Lin En’s convenient new trait raises the possibility that the system knows—or has arranged—what is coming.
• Power and control: No-Fly could reshape the battlefield by denying one of its most dangerous advantages: control of the skies.

Key plot points

• Lin En questions the Butcher’s Nails and the strange history of Nuceria, where ordinary humans supposedly subdued Angron despite his immense strength.
• As Daemon Prince Angron flies toward the battlefield, Lin En decides to face him alone rather than summon another Primarch.
• Lin En activates the No-Fly domain across a twenty-kilometer area, refreshing his allies’ buffs beforehand and preparing to fight Angron while keeping the Ultramarines out of the confrontation.
• The domain forces Angron out of the sky. He crashes into the ground, tries unsuccessfully to fly again, and becomes enraged as the Butcher’s Nails intensify his fury.
• Seeing Angron grounded and vulnerable, Lin En prepares to attack.

Character developments and interactions

• Lin En shows strategic confidence, choosing to test his own abilities against a Primarch-level foe. He adapts his skills for the matchup, reasoning that Angron’s reliance on melee makes him vulnerable if he cannot fly.
• Angron arrives in a fearsome, overwhelming display, but the No-Fly domain abruptly strips away his aerial advantage. His frustration quickly turns into mindless rage.
• The battlefield forces—Ultramarines and daemons alike—briefly stop fighting in shock when Angron falls from the sky. Lin En’s priority is to keep his allies safe while he handles the Daemon Prince.

Significant themes

• Strategy over brute force: Lin En hopes to overcome a vastly powerful enemy by exploiting a specific weakness rather than matching strength with strength.
• Power and vulnerability: Angron’s dramatic entrance gives way to an undignified crash, showing how quickly a formidable warrior can be unsettled by the right countermeasure.
• Control and rage: The Butcher’s Nails amplify Angron’s fury, leaving him more dangerous but less composed when his advantage is removed.

Key plot points and events

• Lin En rises into the air with a Psychic Storm, keeping out of Angron’s reach as the Daemon Primarch roars below.
• The chapter explains Angron’s near-total loss of reason after his ascension. The Butcher’s Nails have become part of his daemonic body; he can usually only roar and snarl, with rare moments of clarity.
• Lin En reflects on the harm Angron and Perturabo inflicted on their Legions. Angron forced the War Hounds to accept the Nails, transforming them into the violence-driven World Eaters. Perturabo ordered the decimation of the Iron Warriors after a costly but successful campaign, killing one in ten of his own warriors.
• Lin En uses anti-daemon weapon enchantment and the Emperor’s Gaze to weaken Angron, then traps him in a golden Psychic Storm. Angron is wounded by the storm’s blades but breaks out through force of arms and Warp power.

Character developments

• Lin En reveals a strong moral opposition to Primarchs who abused their sons. Though he considers Angron beyond saving and pities his torment, he still prepares to fight him.
• Angron is portrayed as almost entirely consumed by the Nails and Khorne. His past capacity for speech and flashes of memory contrast with his present, largely mindless violence. In battle, he remains powerful and instinctively recognizes Lin En’s attempt to contain him.

Significant themes

• The abuse of loyalty: Both Primarchs exploited their warriors’ devotion, turning trust and reverence into tools of cruelty.
• Loss of humanity: The Nails extinguished the War Hounds’ empathy and discipline, while Angron himself became a remnant of the man he once was.
• Victory and punishment: Perturabo’s decimation shows how warped standards of perfection can make even success grounds for atrocity.
• Pity amid judgment: Lin En condemns Angron’s actions while recognizing that the Daemon Primarch is trapped in a state of profound suffering.

Character interactions

• Lin En and Angron face off across the battlefield: Lin En attacks from above and tries to contain and weaken him, while Angron responds with roars, a charge, and brute force.
• The chapter also recalls Angron’s damaging relationship with the War Hounds, whose longing for his acceptance led many to volunteer for the Nails.
• Perturabo’s relationship with the Iron Warriors is presented through his punishment of them after the Incalladion campaign.

Plot points and events

• Lin En keeps Angron at a distance with flight, psychic storms, and Dimensional Slashes. Angron repeatedly breaks free and charges, but Lin En’s No-Fly effect prevents him from taking to the air.
• Lin En’s attacks barely penetrate Angron’s defenses, and Angron’s wounds heal quickly. Focusing repeated slashes on the same spot finally inflicts deeper flesh wounds, but the fight remains a stalemate.
• Unable to reach Lin En, Angron throws rocks, armor, Berserkers, and daemon engines at him. Lin En dodges while continuing to attack.
• Angron turns toward the Ultramarines, threatening their line. Lin En follows, uses Group Healing to refresh his warriors, then draws Angron away before he can reach them.
• Lin En leads Angron through the Khorne army’s formation. Angron charges after him, trampling and scattering his own forces.

Character developments

• Lin En recognizes that his current attacks cannot defeat Angron quickly. He adapts his tactics, protects the Ultramarines, and deliberately redirects Angron toward the enemy’s ranks. He briefly reflects on Angron’s suffering and the Butcher’s Nails, but prioritizes his own warriors.
• Angron remains overwhelmingly durable and increasingly driven by rage. The Nails leave him with little reason and make him easy to bait, even causing him to turn on the Khorne forces around him.

Character interactions

• Lin En and Angron engage in a prolonged contest of pursuit: Angron charges and throws objects, while Lin En flies, evades, and attacks.
• Lin En uses Angron’s fixation on him to draw him away from the Ultramarines and into the Khorne army, protecting his troops at the enemy’s expense.

Significant themes

• Practical strategy over brute force: Lin En cannot overpower Angron, so he relies on positioning, distraction, and the battlefield.
• Protection and loyalty: Lin En chooses his warriors’ safety over confronting Angron directly.
• Rage and suffering: Lin En considers how pain may have shaped Angron, while the Butcher’s Nails keep Angron trapped in fury.
• Irony of uncontrolled violence: Angron’s pursuit turns his own army into collateral damage.

Key plot points and events

• Lin En uses flight, Dimensional Slash, and psychic storms to keep Angron at a distance while steering the enraged Daemon Primarch through Khorne’s own forces, killing many daemons in the process.
• At Calgar’s order, Hera Fortress opens fire on Angron. Lin En pins Angron’s legs with a focused psychic storm, leaving him exposed to the bombardment.
• Lin En enchants his own attacks and the fortress guns to deal extra damage to daemons. With Angron unable to dodge or heal, the combined assault breaks him: his arms are severed, his axe is lost, and he collapses.
• Lin En tries Purification, hoping to remove the cause of Angron’s condition, but discovers it cannot affect the Butcher’s Nails. He then kills Angron with Dimensional Slash. Angron’s body dissolves into the Warp, so Lin En has defeated him but not permanently erased him.
• Afterward, Lin En realizes he has defeated a Daemon Primarch without calling for a Primarch’s help. Exhausted, he sits alone and cries.

Character developments

• Lin En proves how much stronger and more capable he has become. His tactical control, battlefield abilities, and resolve let him defeat an opponent he once could not have faced. Yet victory also brings grief and regret: he wishes he had had these powers when Tyrennius faced the Khorne daemons.
• Angron is driven entirely by the Butcher’s Nails. Unlike a more calculating daemon, he cannot retreat or distinguish allies from enemies, making him both destructive and vulnerable to Lin En’s strategy.
• Calgar responds quickly and decisively, risking disciplinary consequences to support Lin En with the fortress’s guns.

Significant themes

• Strength gained too late: Lin En’s new power is a triumph, but it cannot undo earlier losses.
• Tactical strength over brute force: Lin En wins through flight, crowd control, coordination, and careful use of his abilities rather than matching Angron’s strength directly.
• Angron’s enslavement: The Butcher’s Nails, rather than Chaos corruption alone, are identified as the source of Angron’s state—and as something Lin En cannot purify.
• Victory without closure: Angron is defeated but returns to the Warp, leaving the possibility of his return unresolved.

Character interactions

• Lin En manipulates Angron into trampling Khorne’s daemons, then traps him so Hera Fortress can bombard him.
• Calgar and the fortress crews coordinate their fire around Lin En’s position, supporting him while trying not to hit him.
• Lin En ultimately leaves Angron’s fate to “Yellow Pelt,” acknowledging that the conflict between father and son is not his to settle permanently.

Plot points and events

• During the battle for Macragge, Lin En falls after defeating Khorne’s Daemon Prince. Gabriel and Sentoyor rush to him, fearing he is badly hurt, but stop when they see him crying.
• The two Chapter Masters keep the other warriors away to give Lin En privacy. Meanwhile, the Blood Angels and Ultramarines finish off the remaining daemons.
• Macragge’s defense ends in victory: both the Khorne Greater Daemon and Daemon Prince are banished, and the invading force is destroyed.
• Lin En eventually recovers, boosts the allied warriors, and enchants their weapons so they can continue killing daemons. He vows to one day destroy Khorne’s throne and realm.

Character developments and interactions

• Lin En’s tears reveal a vulnerable, emotional side beneath his power. Once composed, he channels his feelings into renewed determination to fight Khorne.
• Gabriel and Sentoyor show care and respect by recognizing Lin En’s distress and protecting his space rather than pressing him for an explanation.
• Their authority keeps the other Astartes at a distance, while the warriors accept the order and return to the fighting.
• The chapter’s afterword argues that Angron’s suffering and the Butcher’s Nails do not absolve him of responsibility for his actions, including encouraging their replication among the World Eaters. The author expresses solidarity with loyalist soldiers killed by the rebel Primarchs.

Significant themes

• Vulnerability and compassion: Even powerful leaders can break down, and their companions can support them by giving them space.
• Duty and resilience: Lin En turns grief into action, and the allied forces continue fighting after their victory over the major daemons.
• Accountability amid suffering: The afterword distinguishes understanding a character’s tragic circumstances from excusing the harm they caused.

Plot points and events

• Ultramarines finish clearing the battlefield after defeating the Khorne forces on Macragge, destroying the remaining enemies and recovering the dead and wounded.
• The Blood Angels arrive at Hera Fortress only after the fighting has ended. Dante and his captains are astonished and disappointed to have missed the battle, but they join the cleanup rather than complain.
• Lin En realizes he forgot his promise to give the Blood Angels a chance to earn battle honors. Dante accepts his apology, emphasizing that Macragge’s safety matters more than honors, and they agree to fight together another time.
• Afterward, the Ultramarines and Blood Angels prepare a victory celebration. At the suggestion of Nuaus of the Holy Angels, they decide to hold a Blood Angels-style Bonfire Festival in Laphnis Valley instead of a formal fortress banquet.

Character developments

• Lin En feels awkward about overlooking the Blood Angels’ intended role and promises them another opportunity.
• Calgar welcomes the Blood Angels’ help and proves willing to set aside Ultramarine formality for a livelier celebration.
• The Blood Angels and their successors demonstrate camaraderie by pitching in with the cleanup and accepting that their contribution came after the battle.

Significant themes

• Brotherhood over glory: The Blood Angels miss the chance to earn honors, but treat Macragge’s safety as the real victory.
• Humility and shared labor: Rather than dwell on their lateness, the arriving warriors help clean the battlefield.
• Tradition and adaptation: The Ultramarines adopt the Blood Angels’ Bonfire Festival, blending Chapter customs in celebration.

• Dante exchanges greetings and thanks with Calgar, while Lin En apologizes for the missed opportunity and promises a future one.
• Nuaus suggests the Bonfire Festival to Calgar, and an Ultramarines captain enthusiastically supports the idea, prompting Calgar to approve it.

Key plot points and events

• The Ultramarines and Blood Angels prepare a lavish victory bonfire on Macragge, drawing on Ultramar’s abundant supplies. The Blood Angels contribute spices from Baal, which pair perfectly with Macragge’s roasted meat.
• At Calgar’s invitation, the Ultramarines are free to relax. As dusk falls, the Chapters light dozens of bonfires and spend the night eating, drinking, singing, and dancing.
• At dawn, the Ultramarines clean the valley. With the celebration over, the Blood Angels and Lin En’s Chapter prepare to return to their respective homes.
• Calgar personally bids them farewell. The fleets part at the edge of the Macragge System, heading toward Baal and Bolomite.

Key plot points and events

• After returning from Macragge, the fleet arrives at Bolomite, their new homeworld. The warriors celebrate the prospect of having their own repair facilities, supplies, and medical support.
• Lin En draws Space Adaptation, a minor trait that lets him survive in space for one extra minute. He later draws Whisper Resistance, which protects against Warp whispers for thirty minutes, and considers using it to strengthen one of his more useful abilities.
• Bolomite’s construction progresses steadily, while nearby Echo Star develops into an agricultural world. Sentoyor takes the group to see its thriving fields; the first harvest looks promising, and the settlement may become self-sufficient within three years.
• Bolomite’s factories equip the Lamenters, Flesh Tearers, and Blood Knights with abundant weapons and supplies. The Chapters also clear daemons from the Maelstrom’s entrance, leaving it nearly deserted.
• Just as the new life appears secure, a report arrives: a Tyranid fleet has been detected near Echo Star.

Character developments and interactions

• The returning warriors’ excitement reveals how deeply they value the security and independence of a home base. Lin En shares their delight, though he teases them about crowding the viewports.
• Phoros welcomes the fleet, then seems to reconsider his earlier worries when he sees everyone returning cheerful and unharmed. Lin En chases after him, laughing.
• Sentoyor proudly shows the group Echo Star’s successful crops, underscoring his investment in the colony’s future.
• Phoros inspects the newly stocked armory, a quiet sign of how much the Chapters’ circumstances have improved.

Significant themes

• Security and renewal: A homeworld, plentiful equipment, and productive farmland offer the Chapters a rare prospect of stability.
• Hard-won optimism: The Maelstrom remains dangerous and Bolomite is an inhospitable industrial world, but collective effort is turning both into the foundations of a home.
• Fragility of peace: The Tyranid report abruptly threatens the progress and hopeful routine they have built.
• Authorial commentary on character and history: The appended note rejects attempts to excuse Perturabo’s decimation of the Iron Warriors, arguing that it was a deliberate, arbitrary act of cruelty and authority—not punishment for disobedience.

Plot points and events

• Lin En visits Bolomite’s industrial district, where Iron Hammer is overseeing weapons production. He jokes that Iron Hammer is a “wage slave,” prompting Iron Hammer to throw a sword hilt at him; Valerian catches it before anyone is hurt.
• Nearby Lamenters veterans joke that Iron Hammer once carried three steel beams at a time, surprising Lin En, who had assumed Iron Hammer’s strength came from desperation.
• The calm is broken by an orbital-defense alarm. A messenger reports that a Tyranid fleet is approaching from the Maelstrom and is expected to arrive in three days.
• A flashback shows the duty officer recognizing the fleet’s distinctive, signal-erasing Shadow in the Warp by consulting a training manual, then raising the alarm.
• At the defense center, Lin En identifies the phenomenon and concludes the fleet is almost certainly Hive Fleet Kraken, whose numbers and infiltration abilities make it especially dangerous. Its course points directly at Bolomite. The chapter ends with someone shouting a defiant challenge to the Great Devourer.

Character developments and interactions

• Lin En is relaxed and playful with Iron Hammer, but immediately becomes focused when the threat is reported. He recognizes the Tyranid signature and assesses the danger.
• Iron Hammer is shown as both a demanding production supervisor and extraordinarily strong. His irritation at Lin En’s teasing is undercut by the veterans’ amused stories.
• Valerian calmly protects Lin En by catching the thrown sword hilt, then warns Iron Hammer with a look.
• The veterans share friendly banter about Iron Hammer, revealing their camaraderie and improving spirits.

Significant themes

• Hope interrupted by war: Bolomite’s industry, farmland, and lively daily life signal a brighter future, but the approaching Tyranids threaten to destroy it.
• Preparedness and vigilance: Even a quiet watch station and a training manual can prove crucial when a familiar enemy appears.
• Comradeship and morale: Teasing, shared stories, and productive work show people rebuilding their lives and bonds despite the danger ahead.

Summary

• Lin En orders the Blood Knights to return to Echo Star, activate its defenses, and evacuate civilians to Bolomite if the planet cannot be held. He stresses that people matter more than crops.
• Remembering that Hive Fleet Kraken nearly destroyed the Lamenters and the Emperor’s Scythes in the past, Lin En warns Marneus Calgar that the Scythes’ homeworld, Sotha, may be threatened.
• Calgar quickly checks Ultramar’s border surveillance and confirms there have been no Tyranid signals nearby. Sosila, the Emperor’s Scythes’ Chapter Master, is reassured and does not rush to Sotha.
• Lin En concludes that Kraken has bypassed Ultramar and is concentrating on his region. He refuses Calgar’s offer of reinforcements, confidently claiming his forces can handle the threat.
• Lin En then convenes the Chapter Masters and company captains to prepare for the invasion. They consider possible targets—Bolomite, Echo Star, the Maelstrom, or Lin En himself—and recognize that Kraken may split its forces across several objectives.

Character developments and interactions

• Lin En shows caution by ordering defenses and civilian evacuations, but also displays formidable confidence when he refuses help and declares his force ready to fight.
• Calgar responds promptly and responsibly, checking the threat through Ultramar’s surveillance before offering support.
• Sosila initially panics at Lin En’s warning because he trusts Lin En’s judgment, but Calgar’s evidence calms him.
• Gabriel voices the group’s uncertainty about Kraken’s intentions, underscoring the difficulty of predicting the fleet’s tactics.

Significant themes

• Protecting civilians: Lin En places human lives above agricultural resources.
• Preparedness and uncertainty: Even with extensive surveillance, Kraken’s movements and objectives remain difficult to predict.
• Trust and reputation: Sosila reacts urgently because he believes Lin En is never wrong; Lin En’s fearsome reputation also makes the group consider him a possible Tyranid target.
• Courage and confidence: Lin En chooses to face the threat without reinforcements, while the others plan for the possibility of a multi-pronged assault.

Key plot points and events

• A Tyranid splinter fleet, Kraken, threatens Bolomite. Lin En’s Space Marine officers react immediately, rushing to fight and vowing to destroy every Tyranid force that remains in the galaxy.
• The planet mobilizes for war. Bolomite’s factories switch to round-the-clock production of weapons, ammunition, armor, and equipment. Workers are so eager to contribute that they protest the three-shift schedule, asking to work continuously; Lin En has to explain that production lines, not labor, are the bottleneck.
• Civilians evacuate to underground fortress shelters, while Echo Star’s agricultural districts are assigned to supply the defense. Space Marines guide families and reassure children that they can return home after the fighting.
• The Lamenters, Flesh Tearers, and Blood Knights prepare for combat, receiving weapons, ammunition, and spare armor. Lin En coordinates the planet’s defenses, keeps the fleet’s movements under observation, and readies the orbital guns.
• Bolomite’s shipyards work at maximum capacity, splitting production between warship parts and small spacecraft. Even off-duty workers hand-build rough, improvised vessels to increase Lin En’s supply of craft that can be used against the Tyranids.

Character developments and interactions

• Lin En emerges as the central organizer of the defense, coordinating military and civilian preparations while remaining attentive to the people’s safety and the Space Marines’ needs.
• The citizens of Bolomite show intense loyalty and gratitude toward Lin En, treating the defense of their new home as a way to repay him. Their eagerness extends from factory workers to families facing evacuation.
• Iron Hammer directs the industrial and shipyard response, urging workers to keep going but also to work safely.
• The Space Marines reassure frightened children and help civilians evacuate. Phoros, meanwhile, privately reflects that Lin En seems to worry excessively about the Lamenters, even though they now have ample supplies and equipment.
• The chapter contrasts the civilians’ humble role in the war with their determination to support the warriors through production and logistics.

Significant themes

• Gratitude and loyalty: Bolomite’s citizens willingly risk exhaustion and hardship because they feel Lin En gave them a home and a future.
• Collective effort: The defense depends not only on soldiers but also on workers, administrators, farmers, and civilians.
• Care amid war: Lin En’s concern for his people and the Marines, and the warriors’ promises to the children, temper the chapter’s martial urgency.
• Preparation and resolve: The planet turns its entire economy toward resisting Kraken, determined not to let the Tyranids escape or destroy their new home.

Plot points and events

• Lin En inspects Iron Hammer’s shipyard and learns that more than two thousand small civilian ships have been built. He points out that their portholes, control consoles, defenses, and other features are unnecessary for his plan: his Machine Spirit Resonance will let the ships pilot themselves, and many are intended for suicide attacks against the Tyranids.
• He orders Iron Hammer to redesign the ships for the lowest possible cost. Iron Hammer initially misunderstands Lin En’s plan, then leads him to a shantytown beside the shipyard.
• There, workers have been hand-welding crude, barely spaceworthy “iron box” ships in their spare time. Lin En recognizes them as exactly what he needs. Iron Hammer estimates they will cost about seventy percent less than standard ships, so Lin En approves producing them in large numbers before the Tyranid fleet arrives.
• The workers, who had been quietly worried their rough efforts would disappoint Lin En, are relieved when he approves the design.

Character developments and interactions

• Lin En shows practical ingenuity and a strong focus on economy, insisting that the ships need only fulfill their purpose rather than meet conventional standards.
• Iron Hammer moves from bafflement and frustration at Lin En’s assumptions to recognizing the value of the workers’ crude designs and calculating their cost advantage.
• The workers demonstrate loyalty through voluntary labor, even being prepared to pilot the ships themselves if Lin En’s warriors reject them.
• Valerian and Carl, hearing the workers’ private conversation, recognize that their devotion is sincere. Lin En then treats the workers’ work with approval rather than scorn.

Significant themes

• Loyalty and sacrifice: The workers’ willingness to risk their lives reflects genuine devotion, not a performance.
• Practicality over perfection: In a desperate war, cheap, expendable ships may be more useful than expensive, fully equipped ones.
• Human resilience and faith: The Custodians see the workers’ courage as evidence that humanity’s spirit endures despite the darkness.
• Recognition and dignity: Lin En’s approval reassures the workers that their efforts have helped rather than hindered their lord.

Chapter summary

• Bolomite’s defenses are readied: Iron Hammer converts the production line to build Lin En’s crude, low-cost “iron boxes”—fast, disposable aircraft with minimal finishing or calibration. Production surges to ten per minute, eventually putting at least a hundred thousand into orbit. Though appalled by their appearance, Iron Hammer recognizes their value and keeps building.
• The Tyranids close in: The Kraken Hive Fleet continues directly toward Bolomite, expected to arrive in twenty-four hours. Lin En warns Dante that scattered tendrils might threaten Baal, where the Blood Angels guard Sanguinius’s remains. Dante agrees to raise vigilance but worries this could leave Bolomite without support. Lin En insists his forces are sufficient; Dante is reassured, though he warns that Kraken is cunning and unlike Leviathan.
• Final preparations: Bolomite’s immense stockpile of ammunition and other supplies is nearly complete. An old worker prays for the Angels’ safety as the final ammunition shipment leaves. Iron Hammer, exhausted after two sleepless days, is relieved that the production effort is finished.
• Forces take their positions: The Flesh Tearers are assigned to defend Bolomite, the Blood Knights to defend Echo Star, and Lin En will lead the Lamenters fleet to meet the enemy. Phoros waits aboard the Night Goddess, while Sentoyor surveys Echo Star’s thriving farmland and resolves to protect the planet.
• The battle approaches: Bolomite’s forces are ordered to full readiness, with shields, guns, and reconnaissance systems prepared. Their declared objective is to draw the Tyranids in and ensure they never leave.

Character developments and interactions

• Iron Hammer sets aside his professional pride and commits fully to Lin En’s unconventional plan, driven by trust and responsibility.
• Lin En is confident and protective: he alerts Dante about possible danger to Baal but refuses to pull the Blood Angels away from their own defenses. His bravado reflects his faith in his overwhelming psychic power and Bolomite’s preparations.
• Dante takes the warning seriously, balancing concern for Baal against the desire to help Bolomite. His exchanges with Lin En reveal both his caution and his growing recognition of Lin En’s strength.
• Sentoyor shows a personal attachment to Echo Star, seeing its beauty and productive fields as worth defending.

Significant themes

• Pragmatism over perfection: The ugly aircraft sacrifice craftsmanship for speed and quantity.
• Trust and responsibility: Iron Hammer’s work and the troops’ preparations stem from confidence in Lin En’s judgment.
• Duty and sacrifice: Workers, commanders, and warriors all contribute to the coming defense.
• Protecting what matters: The chapter contrasts military preparations with Baal’s sacred relics and Echo Star’s peaceful fields—reasons the characters are fighting.

Lin En led the Night Goddess's fleet to intercept Hive Fleet Kraken before it reached Bolomite, using his psychic power to devastate the Tyranid vanguard. He then prepared to send expendable ships into the fight while keeping his Astartes warships back, determined to protect the crew he had come to care about.

• Bolomite detected Hive Fleet Kraken approaching, and Lin En led the Night Goddess and the Lamenters' Battle Barge out to meet it.
• The fleet lost long-range communications in the Shadow in the Warp and formed a battle line between Kraken and Bolomite.
• Lin En strengthened the fleet with his aura, then unleashed Psychic Overload and Psychic Storm to destroy a large portion of Kraken's vanguard.
• After his psychic power waned, Lin En used Machine Spirit Resonance to prepare expendable ships to wear down the Tyranid fleet.
• Lin En kept his Astartes warships back and resolved to fight first rather than risk his crew in avoidable deaths.

Lin En used waves of explosive iron-box ships to hold back Kraken’s Tyranid fleet while the Lamenters and Guard provided fire support. As the battle became a war of attrition, he reflected on how unstoppable the Imperium might be if the Men of Iron had never been banned.

• Lin En launched 250 autonomous iron-box ships, which fired on Tyranid Bio-ships and detonated themselves against them.
• More iron-box ships continuously replaced the destroyed drones, trading cheaply for Bio-ships and burning their biomass.
• The Lamenters and the mortal Guard Army fired from behind the drone line, targeting larger Bio-ships and supporting the defense.
• Lin En watched the battle aboard the Night Goddess and considered how machine armies could let humanity overwhelm most of the galaxy in a war of attrition.

Lin En’s fleet devastated the Kraken fleet with a day of suicide attacks, but dwindling drones and exhausted production forced him to order Bolomite’s workers into shelter. Iron Hammer sent the final batch of Iron Boxes to orbit, while the workers refused to leave the factories until the last transport departed.

• Lin En’s Iron Box drones destroyed nearly half the Kraken fleet, though fewer than two thousand remained and Bolomite’s production was nearing collapse.
• Lin En ordered the fleet to prepare, the Industrial Zone to stop production and evacuate, and the Flesh Tearers and Blood Knights to ready their ground defenses.
• Iron Hammer received Lin En’s order to shut down the furnaces and send the workers to the Underground Bunker, but insisted on finishing the last batch of Iron Boxes.
• Iron Hammer ordered the workers to load explosives onto the final Iron Boxes and send them into orbit before the Industrial Zone shut down.
• The workers watched the last transport truck leave, but stayed gathered outside the factories as Iron Hammer urged them to take cover.

As Kraken’s Tyranid fleet overwhelmed the dwindling Iron Boxes, Lin En authorized Phoros and the Lamenters to lead the charge. He completed the Innumerable Enemy Kills achievement and began its guaranteed gold draw, whose result had not yet appeared.

• Lin En watched the Iron Boxes dwindle and granted Phoros permission to lead the Lamenters’ charge against the Tyranids.
• The Lamenters’ Battle Barge and two escort frigates advanced as the final Iron Boxes and the Lamenters’ gunships moved to intercept Kraken.
• Lin En received the Innumerable Enemy Kills achievement after the system explained that Kraken was the last surviving major Tyranid fleet.
• Lin En questioned the system’s guaranteed gold draw, then chose to draw a trait.
• A gold-and-multicolored Trait Roulette appeared and spun into a glowing galaxy.

Lin En gained Swarm Domination, a trait that let him sever Tyranids from the Hive Consciousness and control them with his psychic power. He used it with Psychic Overload to throw the Kraken fleet into chaos, then stopped Phoros from turning the feat into worship.

• Lin En obtained Swarm Domination and realized his psychic traits formed a set that could let him command millions of Tyranids.
• The system told Lin En that his current psychic power could control about 2.4 million Tyranids, or ten million with Psychic Overload.
• Lin En stopped Phoros and the Lamenters from charging the Tyranid formation, then equipped Psychic Overload and Swarm Domination.
• Lin En combined the traits to block the Hive Consciousness, severing the Kraken fleet's connection to the Great Devourer and leaving the swarm disoriented.
• Phoros praised Lin En's radiance, and Lin En cut in to stop him from worshipping him.

The multicolored canopy killed the Kraken Hive Overlord, severed the swarm from the Hive Consciousness, and took control of most of its Bio-ships. As the Tyranids devoured one another, Phoros ordered the Lamenters to remember the display and keep a pious account of their lord’s power.

• The canopy blocked the Hive Overlord’s signals, compressed and destroyed his psychic nodes, and severed the Kraken fleet’s connection to the great devourer.
• The multicolored light connected to the Kraken Bio-ships’ psychic nodes and restored their orders under its control.
• The Bio-ships turned on their own kind, and more than a thousand Tyranid vessels began devouring one another.
• Phoros’s deputy questioned how the Tyranids could obey their lord, and Phoros claimed they had accepted him as their king.
• Phoros told the Lamenters to remember the day and forbade rumors that contradicted the story that their lord’s radiance had purified the Tyranids.
