Arc 18The Rust Plague and Warp Gate

Atia’s Thousand Sons and Phelps’s Death Guard attacked Brevis, while Dominic’s forces fought to contain the Warp domain and the Rust Plague. Lynn purged the Gemstone’s Machine Spirit of corruption, but the Thousand Sons’ assault on Midtown and a Chaos Undivided blockade at Saint Garus Castle left the conflict unresolved.

  • Bishop Jensen and Colonel William prepared Midtown’s defenders as Rena mobilized the undercity forces, and Atia arrived through Warp rifts with his Thousand Sons warband.
  • Phelps’s hidden plague invasion slaughtered Keller’s squad and spread through the Gemstone’s lower decks, overwhelming successive Imperial defenses.
  • Dominic led the defense of the machine temple, where Sisters of Silence weakened Phelps’s Death Guard and Dominic beheaded Phelps.
  • Barlow and Coren revealed Phelps’s plan to corrupt the St. Garus Knight House and search for a Great Conspirator spell fragment, then killed themselves rather than remain corrupted.
  • A surviving plague seed infected the Gemstone’s Machine Spirit, and Dominic entered its consciousness while Lynn used Sorine as an intermediary to confront Phelps.
  • Lynn and the Machine Spirit destroyed Phelps and the Rust Plague, after which Lynn subdued the Machine Spirit and Dominic ordered the lower decks searched.
  • Dominic offered orbital support against Atia’s attack on Midtown as Rena reported that the Warp gate would soon close and Chaos Undivided cultists had blockaded Saint Garus Castle.
Chapters 426–450 Vol. 5 Read

Ch. 426Thousand Sons (Part One)

A Warp domain absorbed an orbital lance and revealed the Thousand Sons, escalating the crisis on Brevis into a threat to the entire system. Bishop Jensen ordered a defense of Midtown and committed the Iron Guard 6th Regiment, battle priests, and Sisters of Battle to hold the line.

  • Nine factories poured the souls of their victims into the tumor, which swelled and opened into a flower of flesh.
  • The flower absorbed the orbital lance and created a Warp domain that cut off the area from the outside world.
  • A Thousand Sons warrior emerged from a rift, and Bishop Jensen identified the traitor legion and warned that its sorcerers were its greatest strength.
  • Bishop Jensen ordered the garrison to establish three defensive lines and called on Midtown's clergy to prepare for battle.
  • Bishop Jensen pledged to lead the battle priests and Sisters of Battle at the foremost line, and Colonel William committed the Iron Guard 6th Regiment to hold Midtown.

Ch. 427Thousand Sons (Part Two)

Rena sensed the Imperial defenders’ resolve and mobilized Brevis’s forces to protect Midtown while they bought time. Atia, a Thousand Sons sorcerer investigating the human-Tyranid symbiosis, ordered his warband to clear the defenders so he could reach his target.

  • Rena sensed the garrison’s fear and determination as its soldiers, priests, and Bishop Jensen prepared to hold the line.
  • Rena ordered the undercity’s plague-cleansing forces, Vanguard reserves, and anti-aircraft guns to defend Midtown and the Warp domain.
  • Atia revealed that the Eye of Radicus had shown him a person on Brevis whose fate was blank and whose body was symbiotic with the Tyranids.
  • Atia arrived with an elite Thousand Sons warband, dismissed the Imperial defenders as obstacles, and ordered them cleared away.

Ch. 428The Supreme Thrallband

Atia unleashed his Supreme Thrallband through nine rifts to attack the mid-city, while Commander William’s defenders prepared to fight. The Chaos army’s sorcerous deflection field and healing magic blunted the defenders’ opening barrage, leaving their positions under mounting pressure.

  • Atia summoned sorcerers, Rubric Marines, Scarab Occult Terminators, daemons, and cultists through nine rifts as his Supreme Thrallband.
  • Commander William ordered his soldiers to fire when the Chaos forces came within range and rallied them to fight for the Emperor and Brevis.
  • Bishop Jensen identified the charging Norsac warriors and recognized their champions as Chaos Warriors of Tzeentch.
  • William ordered the defenders to unleash their artillery, but a sorcerous deflection field diverted most of their shots.
  • Norsac sorcerers healed the Chaos Spawn struck by the few shells that hit, intensifying the pressure on the defenders.

Ch. 429The first defensive line fell

Bishop Jensen and William led the defenders of the middle city in a counterattack that briefly disrupted the Chaos army with mines and holy explosives. The charge stalled under the enemy’s strength, and Jensen joined the final wave as the Chaos army resumed its advance.

  • William steadied the soldiers and ordered them to prepare the mine arrays, which blasted apart the Chaos army’s vanguard before sorcerers sent more Chaos Spawn across the field.
  • Bishop Jensen ordered three thousand Ecclesiarchy zealots to attack the enemy flanks, then detonated their bombs packed with martyrs’ ashes and blessed Promethium, engulfing the Norsac warriors in holy fire.
  • William ordered the Iron Guard Assault Battalion to charge through the gaps as the Sisters of Battle and armoured vehicles attacked alongside them.
  • The defenders’ advance became bogged down in close combat, and within five minutes they had lost over half the Iron Guard soldiers, while vehicles were overturned or immobilized.
  • The Chaos army resumed its advance toward the middle city’s core, and Bishop Jensen picked up an officer’s Chainsword and joined the final wave of the charge.

Ch. 430No Ordinary Foe

Captain Keller led military police into the corrupted H4 Living Area, where they discovered the enemy had concealed a large-scale plague infestation. After fighting through a few Flesh Golems, the squad reached the central dormitory gate, which was kicked outward from within and crushed two engineers.

  • Keller found the lowest-deck living area filled with corpses and concluded that a high-ranking mole had falsified inspections and surveillance records.
  • Corpse piles merged into Plague Flesh Golems, and Keller ordered the military police to attack their joints with purifying bolt rounds and sacred flames.
  • The squad burned through the scattered monsters, but Keller suspected the enemy's main force was hiding ahead and ordered the soldiers to search ventilation ducts and maintenance shafts.
  • Keller's squad reached the rust-covered central dormitory gate, and two engineers began planting Melta Bombs to blast its lock.
  • A creature behind the gate kicked it outward, crushing both engineers beneath the massive steel door.

Ch. 431Plague Marines (Part One)

Phelps led twenty-one Plague Marines through a hidden Warp teleportation array onto the Gemstone, where they slaughtered Keller’s naval police squad. The Death Guard’s infiltration had been prepared for weeks, and Phelps revealed that corrupted workers had helped conceal their arrival.

  • Keller ordered the naval police to take cover and fire when the door opened onto twenty-two Plague Marines.
  • The squad’s sanctified ammunition and flamethrowers failed to stop the Death Guard, whose plague quickly weakened and killed the defenders.
  • A plague engineer killed Keller with a rusted warhammer, and the Plague Marines wiped out the three hundred naval police in under ten seconds.
  • Phelps said the Grandfather’s gaze had preceded the enemy’s bullets and explained that he had teleported onto the Gemstone with twenty-one elite Plague Marines.
  • Phelps revealed that Brevis’s undercity contacts had hidden plague spores and teleportation anchors in supply crates, while corrupted workers infected the H4 Living Area and concealed the invasion for five days.

Ch. 432Plague Marines (II)

Phelps planned to reach the Gemstone’s machine temple and corrupt its Machine Spirit, but the Imperial forces sealed off the lower decks. He sent zombies to draw their attention while he and the Plague Marines moved through maintenance shafts toward the defenders’ flank, where he spotted a heavily armed force as ideal prey.

  • Phelps learned that the bridge had sealed the lower decks and sent two naval garrison companies and Skitarii toward Zone H4.
  • Phelps ordered cultists to lead over a thousand Plague Zombies in a feint against the main passage.
  • Phelps and twenty-one Plague Marines climbed through maintenance ducts to flank the Imperial force.
  • Phelps spread the rust plague through the bulkheads and used the ship’s surveillance network to observe the defenders’ positions and weapons.
  • Phelps saw the mixed Adeptus Mechanicus and naval force, including tanks, walkers, and Kastelan Battle Robots, as perfect prey.

Ch. 433Plague Marines (III)

Phelps and the Death Guard used a zombie assault to distract the defenders before unleashing the Rust Plague inside their position. The plague turned the defenders’ machines against them, and the Death Guard slaughtered the mixed force in two minutes.

  • Phelps ordered the cultists to drive the Plague Zombies toward the main entrance and draw the defenders’ attention.
  • The defenders focused on the frontal assault while dark green gas grenades fell from the ventilation ducts and spread the Rust Plague through their position.
  • The Rust Plague corrupted the Servitors, Combat Servitors, and vehicles, while infected Skitarii struggled to fight without their support.
  • Phelps led twenty-two Death Guard through the ventilation ducts and charged the Skitarii line as plague symptoms overwhelmed the defenders.
  • Phelps killed the Tech-Priest, and the Death Guard nearly wiped out the two-thousand-strong mixed force within two minutes.

Ch. 434Plague Marines (IV)

Phelps corrupted the position’s machines and led the Death Guard and Plague Zombies in routing nearly eight thousand Imperial Navy troops. After watching the massacre, Dominic concluded that the Death Guard were targeting the Mechanicus temple and ordered the Gemstone’s forces to regroup there for the battle ahead.

  • Phelps transformed battle robots, walkers, tanks, Servitors, and more than a thousand Plague Zombies into a plague force.
  • The Imperial Navy troops opened fire, but the plague machines and twenty-two Death Guard overwhelmed them, routing nearly eight thousand soldiers in minutes.
  • Phelps looked into a surveillance camera before the rust plague consumed it and cut the signal.
  • Dominic assessed the Death Guard’s tactics and the plague’s effects, then identified the Mechanicus temple as their likely target.
  • Dominic ordered the garrison to concentrate around the Mechanicus temple, keep Skitarii out of close combat, and assign Ministorum Priests to every combat detachment.

Ch. 435Plague Marine (V)

Rear Admiral Dominic fortified the plague-free middle decks of the Gemstone, while Phelps prepared a direct assault with reanimated naval corpses and corrupted vehicles. The undead army advanced toward the defenders’ mine-protected line as Phelps ordered it forward.

  • The Rust Plague consumed the Gemstone’s lower decks but stalled at the sacred, Machine Spirit-protected middle decks.
  • Rear Admiral Dominic ordered mobile forces to abandon lower-deck surveillance blind spots and establish defensive lines along the plague boundary.
  • Phelps sensed the defenses and chose to attack head-on through the narrow corridors rather than rely on stealth and ambushes.
  • Phelps raised more than eight thousand plague-corrupted corpses and gathered dozens of infected vehicles into an assault force.
  • The naval defenders prepared heavy weapons, blast walls, and sensor-triggered mines around their first defensive line.
  • Phelps ordered the undead and plague vehicles to advance despite the mines.

Ch. 436Plague Marines (VI)

Phelps and the Death Guard broke through Dominic’s defensive line, overcame its elite guards and Sisters of Battle, and reached the priests. The chapter ended as Phelps’s warriors began slaughtering the priests whose faith had protected the defenders from the Rust Plague.

  • The Death Guard charged the defensive line, smashing through its blast wall before the soldiers could mount an effective response.
  • Dominic’s Ventria elite trapped eleven Plague Marines in a coordinated electrified spear formation.
  • Phelps led the remaining Death Guard around the spear formation, targeting the priests behind the line.
  • The Sisters of Battle defended the priests, but Phelps’s chemical gas grenade slowed them and the Death Guard killed all twelve.
  • Phelps led ten warriors into the priests’ compartment and began slaughtering them.

Ch. 437Plague Marines (VII)

After the priests were slaughtered, the Rust Plague overwhelmed the Gemstone’s first defensive line, forcing Dominic to conclude that only a strike against the Plague Marines’ leaders could save the ship. Despite Karen’s warning about the danger, Dominic resolved to lead his bodyguards and the Sisters of Silence into battle to defend the Gemstone.

  • The plague army overran the first defensive line after the priests’ deaths ended the protection of their faith, and the soldiers fell back or became walking corpses.
  • Dominic received word that his carefully prepared defense had collapsed in less than half an hour and realized the plague would grow stronger as it spread.
  • Dominic decided he had to attack the Plague Marines and their leader himself, accompanied by the Celestial Lion Guard Squad and the Sisters of Silence.
  • Karen warned Dominic not to risk himself, recalling how the Ork warlord Ragnar had nearly killed him aboard the Gemstone.
  • Dominic explained that he could not allow the Gemstone to fall to Chaos, and Karen reluctantly accepted his resolve.

Ch. 438Plague Marines (VIII)

Dominic prepared the Gemstone’s last defenses as Phelps’s plague army grew and reached the machine temple. When the Death Guard charged the final defensive line, Dominic and the Celestial Lions Terminator Squad appeared alongside the Sisters of Silence to face them.

  • Dominic ordered Karen to ready the household guard and Celestial Lions equipment, and told the rear defenses to delay the enemy at any cost.
  • Phelps’s plague army swelled to thirty thousand zombies, gained corrupted vehicles and daemons, and broke through successive defensive lines.
  • Phelps led the army to the machine temple, where Imperial vehicles and Tech-Priests held the final position.
  • The defenders’ fire pinned the zombies, and their defenses suppressed the plague’s effects, prompting Phelps to lead twenty-two Plague Marines in a direct charge.
  • Dominic and six other Celestial Lions Terminators dropped from the ceiling with seven Sisters of Silence, blocking the Plague Marines’ advance.

Ch. 439We are the Death Guard (Part One)

The Sisters of Silence suppressed the Death Guard’s Warp-powered plague, restoring the warriors’ memories and showing them what they had become. Nineteen killed themselves, while two survivors attacked Phelps for leading them into corruption.

  • Phelps recognized the Sisters of Silence as Blanks and realized their null fields were weakening the Death Guard.
  • The Sisters expanded their null fields, cutting the Plague Marines off from Nurgle and restoring their memories of the Emperor’s Death Guard and the Legion’s fall.
  • The Death Guard remembered their past and blamed Phelps, while he insisted that Nurgle’s gifts were their source of strength.
  • Nineteen Plague Marines killed themselves rather than continue living as Nurgle’s servants.
  • The two remaining warriors charged Phelps with a Power Axe and a Power Hammer, intent on killing him.

Ch. 440We are the Death Guard (II)

The Sisters of Silence’s null field weakened the Death Guard, causing nineteen to kill themselves and leaving Phelps fighting Barlow and Coren. Dominic and the Celestial Lions exploited the opening, and Dominic beheaded Phelps, leaving the passage clear of the immediate threat.

  • The null field stripped away the Death Guard’s plague blessings, leaving Barlow and Coren too weakened to fight effectively against Phelps.
  • Phelps urged Barlow and Coren to accept Nurgle’s gifts again, but they rejected him and continued fighting.
  • Dominic recognized that the Sisters of Silence had created a rare tactical opportunity and ordered them to hold their position.
  • Dominic directed the Celestial Lions Terminators to fire precise bursts at Phelps while Barlow and Coren pinned him in place.
  • Dominic charged Phelps and cut through his pauldron and neck, beheading him.

Ch. 441We Are the Death Guard (III)

After the Sisters of Silence neutralized the Death Guard’s corruption, Barlow and Coren surrendered and told Dominic why Phelps had come to Brevis. Their account pointed Dominic toward a hidden fragment guarded by the St. Garus Family, which he suspected was an STC.

  • Phelps exploded in a burst of plague-ridden flesh, but the Sisters of Silence’s null field stripped away its Warp corruption.
  • Barlow and Coren lowered their weapons and explained that they had once fought loyally for the Emperor before the plague and their Legion’s fall.
  • Dominic asked why the Death Guard had come to Brevis, and Coren said Phelps planned to corrupt the St. Garus Knight House into a Rust Hounds warband.
  • Barlow revealed that Phelps was also searching for a spell fragment of the Great Conspirator, said to have fallen on Brevis and been guarded by a family for generations.
  • Dominic connected the guarded fragment to the St. Garus Family and suspected that it was an STC.

Ch. 442The tenacious maggot (part one)

Dominic learned that the St. Garus Family's STC contained a fragment of Tzeentch's sorcery and that a powerful traitor on Brevis had aided Phelps. After Barlow and Coren died, Phelps's hidden plague seed infiltrated the Gemstone's machine spirit throne through a Tech-Priest's robe.

  • Barlow and Coren warned Dominic about Phelps's highly placed accomplice on Brevis and the possibility of hidden plague vessels, then killed themselves rather than remain corrupted.
  • Dominic ordered the entire ship searched and decontaminated, and warned Kerry Von that Brevis had a traitor and the St. Garus Family's STC was tainted.
  • Phelps's tiny plague seed survived the explosion and hid in the robe of a low-ranking Tech-Priest who entered the machine temple.
  • The machine spirit throne struck the acolyte with lightning, killing him and carrying the plague seed into its power circuit.

Ch. 443The Tenacious Maggot (Part Two)

Phelps used the Machine Spirit’s lightning to carry the Rust Plague into the Gemstone’s core, leaving the ship’s systems failing and the Machine Spirit steadily corrupted. Dominic and the priests’ massive purification ritual barely slowed the spread, and the Machine Spirit remained in danger of falling completely within twelve hours.

  • Phelps sent the Rust Plague through the Machine Spirit’s energy circuits, where it spread toward the throne’s core and corrupted the ship’s systems.
  • Dominic received an urgent report and rushed to the machine temple, finding the throne covered in rust and dark green mold.
  • The senior priest told Dominic that the plague had entered through the Machine Spirit’s lightning and could not be stopped by the purification methods already tried.
  • Dominic ordered every priest and sacred resource assembled for the highest-level purification ritual.
  • Nearly a hundred Tech-Priests and Ministorum Priests performed the ritual for three hours, but the Machine Spirit’s purity recovered by less than one percent and the rust continued spreading.

Ch. 444She came

As the Gemstone's Machine Spirit succumbed to the rust plague, Sorine brought Lynn's plan to save it through Dominic's bond with the ship. Dominic introduced her to the machine temple, where she prepared to act despite not knowing exactly how Lynn would carry out the domination ritual.

  • Dominic noticed Sorine's silver-red glow and followed her into a maintenance passage, where she told him she needed his cooperation to save the Gemstone.
  • Lynn's system detected the infected Machine Spirit and revealed that remote domination required an intermediary whose soul was deeply bound to it.
  • Lynn identified Dominic as the ideal intermediary and told Sorine to have him make close contact with the Machine Spirit throne so his soul could serve as an anchor.
  • Sorine entered the machine temple with Dominic and faced the tech-priests and Bishop Venka as Dominic declared that she could save the Gemstone.
  • Sorine trusted Lynn's plan despite doubting that Dominic's contact with the throne could reverse the Machine Spirit's infection.

Ch. 445Facing the Plague

Dominic ordered everyone out of the Machine God's temple and entered the Gemstone's Machine Spirit core to confront the Rust Plague. He discovered Phelps had merged his remnant soul with the plague and was attacking the Machine Spirit, then faced Phelps as moths surged toward him.

  • Dominic dismissed Bishop Venka, the high priest, and the others, then approached the Machine Spirit's throne while Sorine remained behind.
  • Dominic endured the throne's electrical arcs, sat on it, and entered the Gemstone's consciousness.
  • Dominic saw the Machine Spirit's steel wasteland being consumed by the Rust Plague and recognized Phelps's grotesque moth-shaped form attacking it.
  • Phelps mocked Dominic for entering the core and sent a swarm of moths rushing at him.

Ch. 446Switching Players! (Part One)

Lynn took control of Dominic’s consciousness through Sorine and struck back at Phelps in the Machine Spirit’s world. His attack devastated the plague moths but also damaged the Gemstone’s Machine Spirit, forcing Lynn to rein in his power.

  • Sorine reached Dominic’s forehead and became the intermediary soul anchor that let Lynn access the Machine Spirit’s consciousness.
  • Lynn accepted the system’s offer to take control of Dominic’s consciousness and manifested as a powerful phantom in the Machine Spirit’s world.
  • Lynn formed a bone-white greatsword and struck Phelps, erasing a third of the plague moth swarm.
  • Lynn’s attack tore through the Machine Spirit’s metallic foundation and sent its lightning and energy into disarray.
  • Lynn recognized that further damage could cripple the Gemstone and leave it vulnerable to Chaos, so he decided to hold back.

Ch. 447A change of opponent (II)

Lynn and the Machine Spirit joined forces to destroy Phelps’s plague swarm and leave him nearly defeated. As Phelps questioned what Lynn was, Lynn wondered whether the system was an interface to his own Warp power, then pushed the fear aside for now.

  • Lynn refined his purple sword power and precisely cut through Phelps’s plague moths without harming the Machine Spirit’s core essence.
  • The Machine Spirit recognized the moths as its enemy and targeted them with lightning, helping Lynn weaken Phelps.
  • Phelps tried to rush Lynn and accused him of being the False Emperor’s lapdog, but Lynn’s sword strikes kept the moths at bay.
  • Lynn and the Machine Spirit wiped out the swarm, causing the corruption across the world to recede and exposing Phelps’s weakened consciousness.
  • Phelps asked whether Lynn was a newly born Warp god, prompting Lynn to suspect that the system embodied his own Warp authority.
  • Lynn suppressed his fears and reassured himself that his will remained intact and that he could focus on protecting Brevis and living with his beloved.

Ch. 448Lynn Tamed the Rampaging Machine Spirit with One Hand

Lynn destroyed Phelps and the Rust Plague, then subdued Gemstone's Machine Spirit when it attacked him and Dominic. Dominic awoke in the Machine God's temple to find the throne restored and the Machine Spirit stabilized.

  • The Machine Spirit's lightning destroyed Phelps and vaporized the last Rust Plague spores beneath the wasteland.
  • The confused Machine Spirit attacked Dominic and Lynn, but Lynn blocked its lightning and restrained its flood-dragon form.
  • Lynn completed his domination of Gemstone's Machine Spirit and ordered it to obey Dominic and the others.
  • Lynn withdrew from the Machine Spirit world as the subdued flood dragon watched him depart.
  • Dominic awoke in the temple as the Machine Spirit throne renewed itself, and Sorine sensed the Machine Spirit had become stronger and more docile.

Ch. 449Must Have Been Hearing Things

Dominic awoke after the Machine Spirit was restored, though he could not explain how he had survived the encounter. He suspected Kerry Von’s voice had reached him, then collapsed after ordering the sweep of the lower decks to continue.

  • The tech-priests and clergy entered the machine temple and found the Machine Spirit restored, with Dominic unconscious on its throne.
  • Bishop Venka crossed the cordon and helped the others carry Dominic away without the throne’s electrical arcs attacking them.
  • Dominic regained consciousness, heard that the Machine Spirit was fine, and recalled a voice that sounded like Kerry Von’s.
  • Dominic told the gathered clergy that a light had driven away the plague, and they credited the Emperor and the Machine God.
  • Dominic collapsed from exhaustion after ordering Karen not to stop the comprehensive sweep of the lower decks.

Ch. 450A new enemy

Dominic and Isolde prepared to sacrifice Midtown to stop the Thousand Sons, while Lynn recognized that Luna’s collapsing Warp gate was no longer the main threat. As Lynn moved to reinforce Midtown, Chaos Undivided cultists surrounded Saint Garus Castle and cut off every escape route.

  • Dominic learned that the Thousand Sons had attacked Midtown and that the defenders were suffering heavy casualties.
  • Dominic offered the Tithe Fleet’s orbital fire support, and Isolde agreed to evacuate the core area and send bombardment coordinates.
  • Lynn mocked Luna for believing her Gate of Calamity meant victory, knowing her ritual had enabled Atia and the Thousand Sons to arrive.
  • Rena told Lynn that the Warp gate would close within an hour and that the remaining daemons could be defeated, so Lynn ordered a withdrawal toward Midtown.
  • Rena reported that cultists marked by all four gods had blockaded Saint Garus Castle, and Lynn identified them as Chaos Undivided.
