Chapter Summaries

Alex Kane returned to the Dawn Fleet as a military advisor and saw how the Primarchs’ command, resources, and organization had transformed the Astra Militarum, leaving him convinced they represented humanity’s hope. Meanwhile, Ramesses informed Terra of the coming threat, criticized its failing bureaucracy, and suggested testing a radical solution in Segmentum Obscurus.

• At Vigilus Spaceport, the Dawn Fleet organized arriving Astra Militarum soldiers, issued them equipment, and assigned them to a ninety-day training cycle before deployment.
• Alex Kane rejoined the 43rd Cadian Regiment, “Broken Sword,” and shared his battlefield experience as the regiment prepared for war alongside Astartes forces.

• Ramesses received a Terra official in place of Itu Hametallion, handed over the Wings of Dawn’s warning, and condemned Terra’s ineffective administration.
• When an Adeptus Custodes Shield-Captain objected to his suggestion of amputation, Ramesses proposed trying it in Segmentum Obscurus.

The Blood God’s roar unleashed a widespread Chaos assault across the Cadian Gate and the surrounding Sectors, as Imperial forces prepared to resist under the Primarch’s plans. The chapter ended with the Dawn Sector Government formally declaring war and demanding command over all forces in the war zone.

Forge World Cyprus fell under a devastating Chaos and Dark Mechanicum assault as Fabricator Magos Fabian Watts realized his earlier choices had left the planet exposed. After the Ramilles-class Star Fortress collapsed, he reached the Primarchs through a psychic channel and was promised that they were coming.

• Chaos forces and Space Hulks destroyed Mendi's Ramilles-class Star Fortress and devastated Forge World Cyprus.
• Fabian Watts regretted sheltering Mechanicus rebels and refusing the Primarchs' protection as traitors invaded the planet.
• Fabian tried to recover Ravenna's psychic technology from the captured Biologis, but discovered that the tubes attached to his head were Butcher's Nails.
• Fabian reached into the Warp to ask where Lord Romulus and the Primarchs were, and an unseen voice pulled his consciousness back from Chaos.
• The Primarchs' voice asked Fabian about the enemy forces, casualties, and how long Cyprus could hold; Fabian estimated ninety-seven days and asked whether reinforcements would arrive.
• The voice ordered Fabian to hold his ground and promised, "We are coming."

Kosolax tried to disengage from the battle at Forge World Cyprus while the Primarch’s forces closed in, but the phantom officer Lotara Sarrin took command of the Conqueror and ordered the fleet to hold formation. As the enemy arrived, Kosolax’s torment and fear intensified.

• Kosolax watched the Conqueror evade the Star Fortress’s macro-cannon fire while a renegade Battle Barge was crippled.
• Kosolax ordered the fleet to withdraw, maintain orbital bombardment, and prepare the ground forces to retreat from Forge World Cyprus.
• Kosolax reflected on how quickly the Primarch’s forces had crushed other traitor warlords and remembered the Great Crusade.
• Lotara Sarrin appeared on the command deck and ordered the captains to hold formation until reinforcements arrived, then sent Iron Warriors ships to cover the flank.
• Kosolax insisted that the fleet had to leave before the Primarch’s forces arrived, but the Conqueror’s living ship-control mass trembled as he realized they were already there.

Kosolax tried to withdraw his Chaos fleet as a Primarch approached, but the Butcher’s Nails and his followers’ greed forced him to assert control through violence. He destroyed a Night Lords cruiser and threatened to reclaim their battleship, leaving the fleet’s alliance intact but tense.

• Kosolax felt the Butcher’s Nails flare as he warned his followers over an open channel that they should retreat from the approaching golden radiance.
• The Conqueror turned away from the battlefield while Kosolax sent Skull-Hunter Sharok to claim his reward in the dueling pits.

• Kosolax returned to his throne as the Dark Mechanicum lingered, the World Eaters slaughtered, and the Emperor’s Children tortured mortals.

Kosolax withdrew his Chaos fleet as Sanguinius's forces overwhelmed the traitors, while Shaka repented after discovering that Angron had deceived him and charged toward the Blood Angels. Hal killed the mortally wounded Shaka, and Arthur and Ramesses turned their attention to Perturabo's plans and Fulgrim's ascension site.

• Kosolax watched Sanguinius's fleet arrive and crush the disorganized Chaos forces, then ordered his fleet to retreat into the Warp.
• Shaka admitted to Kosolax that he regretted his betrayal, and Kosolax rejected his apology and abandoned him.
• Sanguinius's light revealed to Shaka that the angel who had guided him was Angron, who had deceived him; Shaka then ran toward the battlefield and was killed by Hal's forces.
• Hal found the dying Shaka and delivered the final blow, while Ramesses ended his psychic projection and discussed the battle with Arthur.
• Ramesses proposed investigating the site where Fulgrim had sacrificed Perturabo's power, and Arthur agreed while assigning Luo to accompany him.

Arthur explained that Chaos fleets were regrouping to target Romulus, whose work kept the Dawn Sector and its war effort functioning, and asked Ramesses to protect him. After the planet’s defenders reclaimed key areas, Karna reunited with Romulus and witnessed a corrupted War Hound Titan restored.

• Arthur showed Ramesses that Chaos fleets were avoiding other major Imperial forces and trying to locate Romulus, whom they considered an easy target.
• Arthur explained that Romulus managed the Dawn Sector’s vast administrative and logistical systems, so a decapitation strike against him could bring those operations to a halt.
• Arthur asked Ramesses to remain with Romulus for protection, and Ramesses agreed.
• The defenders recovered the spaceport, the planet’s eastern region, and the western cargo district as Imperial forces cleared the ruins.
• Karna watched the corrupted War Hound Titan’s flesh and spikes burn away, revealing its restored armor and awakening Machine Spirit.
• Karna entered Romulus’s office and saw a Tech-Magos standing respectfully before the blue giant.

After the Chaos invasion devastated Forge World Cyprus-Mendi, Romulus negotiated its reconstruction and exposed the Fabricator General’s allies as would-be usurpers. Fabian Watts accepted a reduced role in rebuilding the planet, while Dawn Sector forces and their partners prepared to oversee its security and production.

• The surviving Blood Angels joined the rescue effort as the battered Forge World struggled to supply its remaining defenders.
• Romulus asked Fabian Watts how long recovery would take, and Watts estimated sixty years with the population left.
• Romulus showed Watts evidence that his allies planned to eliminate him and claim his inheritance.
• Romulus assigned Watts a role in reconstruction alongside Huangquan-8, Agripinaa, and Dawn Sector technocrats, with a six-year target and Dawn Sector heavy-vehicle production licenses.
• Romulus arranged security by the White Consuls and Wings of Dawn and directed that trapped civilian port workers be used for reconstruction.
• Watts accepted Romulus’s terms without objection and agreed to take responsibility for the assigned work.

Forge Director Fabian Watts negotiated with the Tech-Magos to secure his future role in Cyprus under the Dawn Sector government, while Romulus and Arthur discussed the stalled war and arranged a Dark Angels force. Romulus decided to go to Cadia, putting Drakus’s familiar role at risk.

• Fabian Watts gave the Tech-Magos the encrypted Wings of Dawn access key and demanded payment for helping the Primarch establish control over Cyprus.
• The Tech-Magos agreed to the deal, and Fabian returned to the Mechanicus Ark’s bridge to begin planning the Forge World’s reconstruction.

• Arthur agreed to send Azrael’s Dark Angels, while Romulus and Arthur planned defenses and discussed how to counter Chaos raids.
• Garro and Drakus discussed Chaos’s inability to unite its forces, and Romulus decided that they would go to Cadia.

Romulus told Arthur that Ulthwé Craftworld had offered coordinates and intelligence in exchange for the Primarchs releasing Aeldari souls by killing their kin. Arthur learned that the deal concerned the search for Idris, then asked why Romulus still insisted on going to Cadia.

• Romulus showed Arthur a beacon and explained that Idris, an Aeldari colony world deep within the Eye of Terror, had been located.
• Romulus said Ulthwé Craftworld had approached him after its Farseers investigated the Primarchs and their ability to permanently destroy Daemons.
• Romulus explained that Ulthwé offered known Eye of Terror coordinates and intelligence support in exchange for the release of Aeldari souls who had died over the past thousand years.
• Arthur accepted the explanation and asked what the arrangement had to do with Romulus insisting on going to Cadia.

Romulus assessed the enormous Chaos invasion and recognized that his death could collapse the Imperium’s wartime defenses. He chose to reveal his position alongside Cadia, drawing Chaos’s attack toward himself in hopes of easing pressure elsewhere.

• Romulus studied Eldrad Ulthran’s intelligence and learned that over a thousand Chaos warbands might join Perturabo’s invasion.
• Romulus and the others identified Cadia as the highest-priority defensive position, with the Dawn placed immediately after it.
• Romulus concluded that Chaos’s major forces were hunting him because killing him could cripple the Imperium’s defenses and remove its greatest obstacle.
• Romulus weighed whether the Imperium was ready to face a concentrated strike but decided against waiting for better conditions.
• Romulus chose to reveal his position and overlap it with Cadia, drawing the enemy toward him while potentially relieving pressure elsewhere.

Romulus agreed to lead a bait operation with Arthur, Ramesses, and the Angel supporting him, while Drakus prepared to rebuild the Invincible Iron Guard. The chapter ended with Fulgrim watching Angron and Perturabo continue their ancient struggle on Midgard.

• Arthur told Drakus to begin rehabilitating the Invincible Iron Guard and seek more warriors from the Emperor.
• Arthur reassured Drakus that Romulus would have reliable companions and would not face the enemy alone.
• Romulus, Arthur, Ramesses, and the Angel agreed to the Bait Plan, leaving Romulus to arrange its execution.
• Garro noticed Drakus's concealed grin as the others dispersed to carry out the plan.
• On Midgard, Fulgrim taunted Angron and Perturabo as their battle continued beneath clashing Warp Storms.

Angron fought Perturabo on Midgard as the Lord of Iron used the Iron Circle Automata to chain and batter him. Angron's hatred turned toward the Emperor and the mysterious beings near the Conqueror, and he vowed to enter Realspace and confront his brothers, even if they killed him.

• Angron recalled Lorgar's claim that the Butcher's Nails could be endured and turned into strength, but dismissed it as a lie.
• Perturabo attacked Angron with the Iron Circle Automata, then used chains and barbs to restrain him and strike him with Forgebreaker.
• Angron broke into the air with several automata dragged along, and his sight of the Conqueror and nearby shadows stirred jealousy and hatred for the sons who had found release.
• Angron remembered the Emperor's role in his torment and imagined him as he clashed weapons with Perturabo.
• Angron resolved to wield the whip his brothers had built, enter Realspace, and either destroy them or be slain by them.

Perturabo realized that Angron and Fulgrim were slaves to their Chaos Gods and walked away from his stalemate with Angron. Ladis found the disciplined World Eaters and learned they were expected to swear loyalty to Kosolax and the Oathbreakers, while Angron remained trapped by Khorne’s will.

• Perturabo and Angron fought to a stalemate as Fulgrim refused to intervene, claiming Slaanesh would not let him leave his role.
• Perturabo recalled Dorn’s lesson about walking away and released Angron, then realized he had broken free of their pointless struggle.
• Ladis crossed the chaotic arena with only three squad members remaining and found disciplined World Eaters gathered near their gunships.
• Ladis asked where Angron was, and a captain told him Angron was dueling Perturabo and that the World Eaters would swear a blood oath to Kosolax and the Oathbreakers.
• Fulgrim mocked Angron’s helplessness as Perturabo recognized that the Chaos Gods controlled his brothers and abandoned the duel.
• Perturabo returned toward the Iron Blood while Angron struggled against Khorne’s restraint, unable to kill himself or escape his role as a slave.

Terra learned that Romulus had withheld the Segmentum Obscurus’s tithes, but the Primarch’s evacuation and attrition strategy in the Scarus Sector persuaded the High Lords to abandon their impeachment proposal. Navar-Dalen relayed Romulus’s orders to the Navy as the Imperium prepared to abandon a planet and disrupt Chaos’s supply lines.

• Terra discovered that the Wings of Dawn had cut off the Segmentum Obscurus’s tithes, and the Scarus Sector began facing a major Chaos offensive.
• Romulus evacuated civilians, fortified key worlds, and used the Scarus fleet and resistance forces to slow Chaos while redirecting population and supplies to the front.
• After the Adeptus Custodes commander reported the strategy’s progress, Terra quietly put away its impeachment proposal against the Primarch.
• Navar-Dalen relayed Romulus’s orders to Scarus’s naval officers to abandon a planet and use the fleet to cut off enemy supply lines.
• A staff officer reported sightings of Chaos fleets along Malqir’s route and said the enemy appeared to be organizing a supporting offensive.

Frix’s Iron Warriors razed a fortified planet but found its population had been evacuated, leaving them with little to gain from the devastation. As Imperial forces converged and Chaos allies began to desert, Frix and Honsou recognized that the Scarus campaign could not continue as planned.

• Frix destroyed the planet’s surface defenses, and the Iron Warriors besieged its fortified cities while their defenders resisted fiercely.
• After a week of bombardment failed to break the resistance, Iron Warriors commanders ordered orbital strikes that reduced the continent to ruins.
• Frix found the cities empty of civilians and counted losses of a fifth of his forces, while salvaging war machines from the wreckage.
• Frix considered how Romulus’s evacuation of the population had denied the Iron Warriors resources and made their victories difficult to hold.
• Honsou joined Frix and agreed that the campaign could not continue as Imperial forces gathered and Chaos followers began deserting.

Frix joined Perturabo’s fleet after it captured an Imperial battleship, but the Iron Warriors remained trapped by the Imperium’s tightening campaign. He reported that the Dawn Sector Government had won over key Mechanicus forces and gained control of Forge Worlds, undermining Perturabo’s strategy.

• Frix’s fleet emerged from the Warp and approached the Iron Blood, where he saw the captured Retribution-class Battleship and wreckage from an Imperial splinter fleet.
• Frix judged the battle a strategic failure as the Scarus Sector fleet squeezed the Chaos forces and deployed Astra Militarum troops across occupied planets.
• Frix ordered his units back to their posts and brought Honsou with him to report to Perturabo.
• Perturabo continued coordinating the wider war from his throne as Frix delivered a data disk.
• Perturabo learned that the Dawn Sector Government had persuaded Mechanicus forces to accept a new Omnissiah faith, brought Forge Worlds under its control, and commissioned two Retribution-class Battleships.

Perturabo learned that the Wings of Dawn had consolidated the Imperium’s religious, political, and military power, while Chaos forces under his command splintered and his campaign stalled. After hearing that Fulgrim was trapped in a deadly reenactment of the Unification Wars, Perturabo ordered Frix, Falk, and Kosolax to stay as a strange presence diminished everyone else in the room.

• Perturabo reviewed the Wings of Dawn’s control over Imperial religion, administration, military command, and resources, and bitterly compared its support from the Emperor to what he had once received.
• Perturabo asked about the Chaos warbands, and Barban Falk reported that all but Kosolax’s Oath-Breakers had splintered or acted independently.
• Frix reported that the Iron Warriors were stalled in the Scarus Sector while the Space Wolves and Black Templars attacked Chaos forces around the Eye of Terror and the Dawn Fleet gathered near Cadia.
• Barban Falk revealed that Fulgrim and the Emperor’s Children had discovered an illusion-making relic on Planet X-2179 and were reenacting the Unification Wars amid a planetwide drug-fueled carnival.
• A strange pressure filled the room as presences faded, and Perturabo ordered Frix, Falk, and Kosolax to stay.

Perturabo raged at Fulgrim for disobeying his orders and at Chaos warbands for undermining his campaign, then declared that everything was over. Kosolax challenged him to continue the war, saying he would leave if Perturabo retreated, and Perturabo responded with a sneer.

• Charag brought Perturabo the deployment report, and Frix reviewed its account of forces pursuing their own agendas instead of the campaign.
• Perturabo condemned Fulgrim for ignoring his order and watched a vision of Fulgrim celebrated by a maddened crowd on a poisoned planet.
• Perturabo denounced the Chaos Gods and their followers for obstructing his command, then said that it was all over.
• Kosolax told Perturabo that the war was one of glory and that he would leave if Perturabo chose to retreat.
• Perturabo sneered at Kosolax and met his angry gaze.

Perturabo rejected Kosolax’s call to attack, choosing to preserve the Iron Warriors and wait for a better opportunity. Meanwhile, sabotage crippled the Calixis Sector Fleet, and Inquisitor Aglaia’s investigation pointed to Chaos as Romulus’s security tightened.

• Kosolax urged Perturabo to join the campaign while the enemy was vulnerable, but Perturabo ordered the Iron Warriors to retreat and conserve their forces.
• A newly commissioned Retribution-class Battleship exploded at the Mandeville Point, destroying five warships, damaging twenty-three others, and inflicting further losses on allied troops and Knights.
• Inquisitor Aglaia investigated the wreckage with a Kill Team and Grey Knights officer Diego, who reported traces of the Khorne Demon Saruum.
• A Silent Envoy stopped Aglaia’s party and collected blood samples after her psychic seal failed.
• Adeptus Custodes Shield-Captain Marcus and Drakus recognized the threat to Romulus, and Drakus imposed a lockdown on the Dawn and barred further large offline fan meetings.
