Chapter Summaries

Fabius Bile and Ezekiel discovered gaps in their memories after events on the planet, while Ezekiel concealed his confusion and the bodies of two Fallen Angels. The Dark Angels executed Elson Nakir, and Arthur and Romulus turned their attention to dealing with the Hive Fleet.

• Fabius Bile woke from his incubation chamber, learned from Melusine that he had already gone on an operation, and realized he could not remember it.
• Ezekiel reviewed the Consecrators’ records, discovered that two Fallen Angels had been killed, and hid the fact that his memories of the planet were blank from Nakir.
• The Round Table Council found Elson Nakir guilty of killing Dark Angels and Calibanite Knights, stripped him of command, and Gareth executed him.
• Gareth realized that Arthur’s plan would bring new recruits into the Legion and let them learn its history without inheriting the old hatred.
• Arthur told Romulus that he had matters under control, and they agreed to focus on the Hive Fleet.

The Imperial forces converged on Bormina for a decisive defense against the Tyranid Hive Fleet after five years of grinding battle. When Titus killed a Zoanthrope threatening the line, Calgar warned him that his fighting style did not conform to the Codex Astartes.

• Romulus and the expeditionary forces drove the Hive Fleet toward Bormina as fleets gathered to destroy its Hive Ships.
• The five-year battle scarred Bormina with ash storms and lava defenses as the Ultramarines and their allies held the planet.
• A Zoanthrope’s psychic beam shattered the defenders’ line and killed an Ultramarine Librarian and other soldiers.
• Thor Invictus identified the Zoanthrope, ordered the troops to spread out, and requested support from the Chief Librarian.
• Titus killed the Zoanthrope with a Neural Shredder, and Calgar warned him that his fighting style violated the Codex Astartes.

Titus put away the Neural Shredder after Calgar reminded him to follow the Codex Astartes, while Romulus and Calgar discussed the coming political fallout from the war. Ramesses then detonated an overloaded Warp Engine, sending the Tyranid fleet crashing into Vashtorr’s Soul Forge.

• Calgar reminded Titus to follow the Codex Astartes, and Romulus offered an apology that let Titus and the nearby Codex Guard avoid a confrontation.
• Romulus told Calgar that the Tyranid fleet’s attack was faltering, and Calgar revealed that a Terra Investigation Team had arrived before the planned victory celebration on Macragge.
• Romulus said the Expeditionary Fleet had pacified the Eastern Fringe and would hand control to the Ultramarines’ successor Chapters, while Calgar worried that Romulus’s political measures would cause future conflict.
• Ramesses overloaded a battleship-grade Warp Engine inside a Hive Ship while Arthur and Karna fought Norn Assimilators, then teleported away with them.
• The Warp Engine’s explosion tore open a rift that swept Tyranid Hive Ships into Vashtorr’s Soul Forge, where they devoured his war machines and drew an angry accusation against Tzeentch.

After the Behemoth Hive Fleet was destroyed, Romulus oversaw the reclaimed Sectors’ defenses and reconstruction before returning to Macragge with the victorious forces. The Primarchs were welcomed home at a memorial ceremony, and Romulus declared the war over for now.

• Calgar awoke from his coma aboard the Samothrace as it carried him back to Macragge, while the swarm’s loss of unified command left it driven by instinct.
• Romulus ordered the local Chapters to consolidate their defensive lines and left further expansion to Calgar as Imperial forces continued hunting the remaining Tyranids.
• The cleanup operation lasted more than four months, and the Behemoth Hive Fleet was destroyed after all major hive nodes were eliminated.
• Romulus reviewed the reclaimed planets as Ultramarines successor Chapters restored defenses, trained PDF forces, and rebuilt infrastructure across the Sectors.
• Macragge’s Honour returned the sleeping Guilliman to Macragge, where the Primarchs and forces were greeted with a victory celebration and a memorial to the fallen.
• Romulus watched the memorial’s projections of the dead, closed his eyes, and reflected that the war was over for now.

After the war in Ultramar, most allied forces departed for other conflicts, while Terra’s delegation remained to negotiate with Romulus about the region’s political order and the Imperium’s future. Romulus entered the meeting alone, empowered to speak for the other three Primarchs, as the delegation prepared to begin talks.

• Imperial fleets, the Maelstrom Guards, the Black Templars, and the Expeditionary Fleet departed Ultramar, leaving only resident representatives from the reinforcing Chapters.
• Romulus reconsidered the waiting Terra delegation and headed to the Fortress of Hera, where the Lucifer Blacks had taken over security.
• Romulus met the delegation, including Adeptus Custodes inspector Navar-Dalen, who asked where the other three Primarchs were.
• Romulus said the other Primarchs had no role in political affairs and that he was responsible for the negotiations, prompting the delegation to recognize their trust in him.
• The delegation cleared the conference hall for Romulus, and Itu Hametallion watched him enter with a complicated expression.

Romulus negotiated with the High Lords over Imperial Tithes and administrative control in Sectors governed by the Wings of Dawn, arguing that the Imperium wasted most of its tax revenue. The council accepted a limited arrangement backed by the Adeptus Custodes, and the representatives began discussing its specific terms.

• Itu Hametallion cited Lufgt Huron's tax refusal and the High Lords' past rejection of his request to conquer the Maelstrom.
• Romulus declared that Imperial Tithes were mandatory but showed figures indicating that the Ultima Segmentum used less than five percent of its tax revenue effectively.
• Romulus proposed directing taxes from Wings of Dawn Sectors to needy Imperial worlds, with Terra retaining inspection rights and counterpart Sectors chosen from Segmentum Obscurus.
• Romulus asked Navar-Dalen to have the Adeptus Custodes coordinate with the Department of the Interior, and Navar-Dalen assigned himself, Valerian, and one Eye of the Emperor.
• Amotarion requested a specific proposal, and the High Lords began discussing terms for Ultramar and the Maelstrom region.

Romulus and Ramesses advanced plans to resurrect Guilliman, rebuild Ultramar’s military, and establish the Wings of Dawn while visiting Macragge. Romulus urged young people to keep studying before taking on greater responsibilities, and the gathered delegates began considering how to work with the Primarchs.

• Cawl said the Armor of Fate could not preserve Guilliman’s fading soul, while Ramesses outlined a plan to use Ynnead’s power to kill and resurrect him.
• Romulus received the completed plan for restoring Ultramar’s military and discussed securing Ultramar, the Maelstrom, and another backup region with the Invincible Iron Guard.
• Romulus encouraged Sirin and the other young people to study until they were ready to serve humanity’s future.
• Ramesses revealed the Wings of Dawn insignia, and Romulus pointed out that it borrowed elements from several Legions while omitting the Ultramarines.
• Eos Rediella lamented that the Primarchs were not separating, while Amotarion decided to explain his ideas to the representatives of each Chapter.

Calgar rejected Amotarion’s proposal to have Romulus oversee Greater Ultramar, citing Guilliman’s enduring authority over the region. After Amotarion withdrew the proposal, Arthur returned a fallen Ultramarines Apothecary’s Gene-seed to Calgar and confirmed he would handle military affairs alongside Romulus.

• Amotarion asked Calgar whether he would support Romulus overseeing Greater Ultramar, but Calgar refused because Ultramar remained Guilliman’s domain.
• Amotarion decided to apologize in person and abandon the proposal after several Astartes Chapters had refused similar overtures.
• Calgar learned that Arthur’s apparent Ultramar civil servant companion was a Callidus Assassin, and that Terra and the Wings of Dawn had reached a broad consensus.
• Arthur gave Calgar the Gene-seed of the Ultramarines Apothecary who had died fighting alongside him, and Calgar promised to honor the warrior’s legacy.
• Arthur told Calgar that he would handle military affairs in parallel with Romulus, and Calgar recognized him as the Warmaster.

Huron discussed plans to develop the Maelstrom into a centrally coordinated defensive and industrial region, while trying to recruit Chapter representatives and build influence. As Arthur reviewed plans to reduce dependence on the Adeptus Mechanicus, he considered Guilliman’s substantial power and ambitions.

• Huron invited Torcilla to support the Maelstrom’s new military project, but Torcilla initially cited his Chapter’s duty to protect Sotha.
• Huron offered Torcilla a share in future equipment trade, and Torcilla agreed to consider supporting the project.
• Torcilla questioned whether the plans would proceed without the Adeptus Mechanicus, and Huron said the Primarchs would likely help free the project from its control.
• Arthur reviewed the Icarus Protocol and anti-Adeptus Mechanicus records, then surveyed the Chapter representatives and noted the Ultramarines’ overwhelming presence.
• Arthur reflected that Guilliman had already achieved his desire for power.

Arthur and Karna discussed the pressure of guiding the Imperium’s faithful and the conflict between the Imperium, the Ecclesiarchy, and Forge World Talentus. Talentus had forced the Imperium to concede restoration work in the Damocles Gulf, while the Wings of Dawn remained confident that their independence from the Adeptus Mechanicus would protect them from retaliation.

• Karna escaped his church duties and joined Arthur, who was studying records about the Icarus Protocol.
• Karna reflected on the enormous hopes Imperials placed in the Primarchs and on the need to direct their faith away from Chaos.
• Karna told Arthur that an Ecclesiarchy representative had approached him about the conflict with Talentus.
• Arthur explained that Talentus’s exploration fleet had tried to seize STCs, then vanished after its Magos died, prompting Talentus to complain and pressure other Imperial departments.
• The Imperium yielded to Talentus by assigning it restoration work in the damaged Damocles Gulf.
• Arthur concluded that the Adeptus Mechanicus could not easily threaten the Wings of Dawn because they had independent technology, production capacity, and military strength.

Arthur and the other Primarchs prepared to establish the Wings of Dawn in the Dawn Sector, break the Adeptus Mechanicus’s monopoly, and bring specialized training and production under their control. As new training began and Cawl developed an experimental engine, the Wings of Dawn’s effort to build a new order moved from planning toward implementation.

• Arthur and Karna agreed that the Wings of Dawn needed to break monopolies, and Arthur confirmed the Dawn Sector as their foothold while anticipating conflict with the Adeptus Mechanicus.
• Karna reviewed Arthur’s contingency plans and worried they were preparing for a war, while Arthur presented a framework for training Librarians, Apothecaries, Techmarines, and other specialists.
• Arthur invited the Chapters to discuss the training framework, which aimed to sever the Space Marines’ dependence on the Adeptus Mechanicus and place them under centralized management.
• Huron examined the plans and recognized the Primarchs’ attempt to centralize power and create a new path beyond the existing monopolies.
• Lohoc and Cawl inspected an experimental engine as Cawl continued developing it, while selected Space Marines and technical workers began specialized training across the fleet.

Romulus investigated corruption across the Dawn Sector while the Dawn Fleet fought raiders and avoided imposing direct rule, leaving local nobles uncertain about his intentions. As most nobles indulged in tax-free extravagance, a few recognized the warnings in his political advice and began preparing for a coming crackdown.

• The Dawn Fleet entered the Dawn Sector and spent six months answering distress calls, while Romulus offered local leaders advice without issuing compulsory orders and Karna spread the Dawn Church’s teachings.
• Reports from Alpha Legion and Dark Angels agents revealed widespread corruption, privatized defense forces, and exploitation across the Sector’s worlds.
• Romulus reviewed the reports above Astogius and condemned a ruling order dominated by nobles and family ties.
• The High Lords accepted the Primarchs’ focus on local problems, while the tax exemption encouraged the Sector’s nobles to spend more lavishly.
• A few perceptive nobles began selling non-core assets, tightening family discipline, and donating wealth to the Ecclesiarchy in anticipation of trouble.

Romulus planned to dismantle the Dawn Sector’s tyrannical noble administration without triggering a devastating civil war, using intelligence, Ecclesiarchy networks, mortal agents, and Astartes strikes. He prepared to assess Astogius while Ramesses worked on an astropathic system that could rapidly connect the Sector’s worlds.

• Romulus showed Karna evidence that Imperial taxation rewarded cruel rulers and described the planned strategy for isolating and eliminating the nobles before they could mobilize the populace.
• Romulus and Karna agreed that the Dawn Sector’s nobles had to be killed, while Romulus argued that sweeping reforms were impossible under the Imperium’s system.
• Romulus cited failed reforms in the Damocles Gulf and the misery of a model tithe world to explain how the Imperium punished reform and rewarded tyranny.
• Romulus contacted Ramesses, who reported that the Dark Angels’ encrypted astropathic channel could deliver orders across a Sector in three minutes when local staff were in place.
• Romulus ended the call and looked toward Astogius, hoping the Cardinal World would prove worthy of his attention.

Romulus and Karna arrived on Astogius, where Archbishop Jorge welcomed them with a grand but restrained reception. During an inspection tour, Romulus learned that Jorge was a moderate reformist trying to navigate the planet’s divided factions.

• The Ecclesiarchy welcomed Romulus and Karna to Astogius with a candlelit reception attended by millions of pilgrims.
• Navar-Dalen complained that the welcome exceeded the Emperor’s recorded ceremonies, and Karna joked that the Emperor had once performed his own miracles.
• Archbishop Jorge greeted Romulus and Karna, then led them on a brief tour instead of holding an elaborate ceremony.
• Karna went to the Cathedral of Dawn for a banquet and transfer of power while Jorge accompanied Romulus on a planetary inspection tour.
• Jorge explained that he supported justification by works and believed the Emperor could protect people who did not believe in His divinity; Romulus asked him to continue.

Romulus inspected Astogius and approved Archbishop Jorge Francisco’s efforts to improve the planet’s industry and food distribution. His tentative confidence in the church collapsed when he discovered believers were burned to produce consecrated oil, so he ordered the practice ended and prepared to clean up the planet.

• Jorge briefed Romulus on Astogius’s production, food supply, and plans inspired by Macragge, while Romulus promised technical support and considered the planet as a possible Sector capital.
• Romulus saw elderly believers burn themselves in a plaza and learned from Jorge that their remains were processed into consecrated oil for church rituals and tithes.
• Romulus contacted Karna, who explained that the sacrifice was unnecessary because the Blood Angels could supply Sanguinius’s blood and that he had already ordered a cleanup.
• Romulus told Jorge that consecrated-oil sacrifices were a bad custom that had to end, then prepared to begin cleaning up Astogius.

Raphael and Sirin uncovered a Chaos ritual hidden within Chahake Cathedral and launched an assault to stop Bishop Jephthah. The battle spread into a slaughterhouse beneath the cathedral, where Raphael and the Purifier Squad faced a powerful Psyker and an unexplored Demon portal.

• Raphael and Sirin suspected a Demon was behind Bishop Jephthah’s disappearance and confirmed that reinforcements were ready to intervene.
• Jephthah began his final ritual, but Sirin opened a gateway to the storm above and lightning shattered the cathedral’s stained glass, freeing the guests from the drugged incense.
• A Stasis Bomb froze the chaos as Imperial forces attacked the heretics below the cathedral, while a powerful Psyker killed two Sisters of Battle with Warp lightning.
• Raphael crushed Jephthah’s head and used fragments of its soul to locate the enemy, then Sirin opened a gateway for the troops despite being unable to penetrate the Demon portal.
• Raphael led the Purifier Squad into a chamber transformed into a slaughterhouse and raised his Holy Sword, calling, “For humanity!”

Raphael, Sirin, and Titus disrupted a Chaos ritual, killed the Bishop, and stopped a Greater Demon from entering Realspace. After the church was evacuated and the mission was reported complete, Romulus assigned Raphael and Sirin to focus on the Chahake district.

• Raphael hurled an Antioch Orb into the heretics, disrupting the ritual and destabilizing the Warp portal.
• Sirin teleported Titus and his squad into the church, where they helped break the heretics' defensive line.
• The Chaos Sorcerers sacrificed themselves to summon a Greater Demon, but Titus killed the final Sorcerer and seized the crystal sword.
• Raphael gave Titus his last Antioch Orb, and Titus dragged a Bloodthirster from the portal before Raphael made it a Daemonhost and destroyed the portal with the grenade.
• Sirin and the Sisters of Battle restored order in the upper church, where an attendant discovered that the Bishop had been killed.
• Raphael and Sirin reported the completed mission to Romulus, who assigned them to the Chahake district.

Romulus reviewed the Dawn Sector’s reforms and preparations while considering how to handle resistance movements and their representatives. When the representatives arrived, they were overwhelmed by his presence and struggled to speak.

• Romulus reviewed planetary reports and kept the foreign nobles from fleeing before their backgrounds had been investigated.
• Sirin and Raphael departed to govern a city that was expected to become the Dawn Sector’s capital.
• Arthur told Romulus that resistance groups led by Bavaria Recruitment World had begun openly opposing their planetary governments, and that one faction leader had arrived.
• Romulus agreed to meet the resistance representatives where he was, and Arthur agreed to teach him beforehand.
• A Watson Planetary Defense Force general led several representatives into Romulus’s office, where they saluted and lost their prepared words under his gaze.

Romulus rejected the nobles’ proposed reforms for turning recruitment worlds into militarized societies and continued organizing practical changes across the Dawn Sector. After he departed to investigate a possible lost world, the chapter showed the Church of Dawn’s aid and registration work for Void-born pilgrims and Archbishop Jorge’s refusal of an extravagant appointment ceremony.

• Romulus dismissed the general’s proposal to transform recruitment worlds, including Watson, according to the Death Korps of Krieg model, and told Arthur that people needed to be taught how to live.
• Arthur established the Watch Order, where Dark Angels trained radical Space Marines from other Chapters in vehicles, equipment, and Legion-era tactics.
• Zabriel reported an ancient Adeptus Mechanicus transmission from Pathfinder III requesting aid, and Romulus ordered a fleet, the Carcharodons, and Karna to accompany the response.
• A Void-born dockworker was directed into a separate line, received food and water after inspection, and was told he could travel on pilgrimage to the surface.
• Archbishop Jorge refused his appointment ceremony and directed the resources meant for it toward visiting pilgrims.

Romulus oversaw the resettlement of surplus pilgrims onto thirteen colonial worlds and reviewed Terra’s unhelpful response while the High Lords and other authorities struggled to purge corruption from the Throne World. As the Dawn Fleet neared the distress signal’s source, Aurora reported that Warp influence was fading, prompting the fleet to prepare for an early transition into Realspace.

• Romulus’s administration began developing thirteen neglected worlds with settlers and teams of technical personnel, Astartes, and mortals.
• A Department of the Interior official processed planetary reports for the Primarch Administrative Council and Terra.
• Romulus read the High Lords’ formulaic reply and reflected on how the Adeptus Custodes’ investigation had uncovered Chaos relics, cults, Genestealers, and other threats on Terra.
• Aurora told Romulus that Warp influence was rapidly fading near their destination and recommended entering Realspace early.
• Romulus approved Aurora’s recommendation and wondered what could be stabilizing reality around the planet.
