Chapter Summaries

Oenomaus trained nomad children in the wasteland before taking his apprentice Spartacus to Mahe City. There, he reunited with the returned Gladiators and their families, who had gathered at KroBio.

• Oenomaus left with Spartacus, his young apprentice, and they rode toward Mahe City with a passing driver.
• Oenomaus and Spartacus passed Mahe City's Orbital Elevator and memorials, and Oenomaus paused in silence before the statue of the child killed during the uprising.
• Oenomaus entered KroBio and asked for Chromachi, who appeared with Qin Xa and the returned Gladiators.
• Oenomaus asked after Kleist and Theseus, then joyfully greeted his returned friends and their families.

Angron reunited with Qin Xa and the others at Chromachi’s mountain resort, where they discussed treating Aven 3’s engineered genetic disease and the Legion’s needs. Angron revealed that the World Eaters’ visit to Nu Star was also the start of a broad reform plan to make the 12th Legion more versatile and address its weaknesses.

• Chromachi welcomed Qin Xa to his brightly lit resort suite, where Brown, Quadrant, and the Olena Sisters joined him.
• Quadrant asked Chromachi to help cure the artificial genetic disease affecting Aven 3’s population, and Chromachi agreed after reviewing the information.
• Chromachi visited Angron and told him that samples had been collected for developing the proposed battlefield medical packs.
• Angron argued that medical packs would protect Legion warriors as the 12th Legion expanded beyond assault warfare, and he marked the proposal complete in his plan.
• Angron considered reforms including expanding the Legion’s Knight and armored forces, establishing rule in more star systems, and strengthening its void power.

At a reunion dinner, Chromachi explained that he and the other Gladiators who drank Angron’s blood had changed and might live far longer, though the cause remained uncertain. When Chromachi grieved over his missing daughter, Angron eased his pain and joined everyone’s hands, sharing their burdens and drawing them closer together.

• Chromachi told the gathered Gladiators that drinking Angron’s blood might explain why they seemed not to age, and Angron said the Legion Apothecaries had found no clear cause.
• Qin Xa suggested that Angron’s powerful wish for the Gladiators to survive, rather than his blood alone, might have caused the change.
• Chromachi admitted that he had sold himself into the Arena to get medicine for his daughter, but had never found her despite years of searching.
• Angron sensed Chromachi’s grief and absorbed some of his pain, giving him temporary relief.
• Angron led the gathering in holding hands and sharing their negative emotions, bringing Gladiators and guests into a closer bond.

After the banquet, Angron told Qin Xa he wanted to expand the 12th Legion and remake its organization before they left Nuceria. He also shared his fear that the Imperium’s suppressed tensions could lead to civil war, and Qin Xa urged him to prepare for the Imperial Council’s rise as the Emperor withdrew from the Great Crusade.

• Angron told Qin Xa he wanted to grow the 12th Legion to about two hundred thousand, and Qin Xa agreed the expansion was feasible.
• Angron explained that he feared the primarchs would stop cooperating and the Imperium could face civil war once the Emperor left the Great Crusade.
• Qin Xa said the Imperium’s contradictions were real but could take a long time to erupt, and Angron insisted the 12th Legion still needed more men and varied units.
• Angron proposed replacing important mortal bureaucrats with Space Marines, and Qin Xa warned him to do so quietly because the Emperor opposed Space Marines ruling.
• Qin Xa advised Angron to prepare for the Imperial Council to replace the War Council by giving up the 12th Legion’s War Council influence and cultivating allies on the Imperial Council.
• Angron accepted Qin Xa’s guidance on expanding the legion and its influence, then said their plans could proceed at the same time.

Kiel sent the 12th Legion’s companies to bring the surrounding worlds under the Primarch’s rule, while Captura’s 37th Armored Company waited for new recruits and upgraded equipment. Qin Xa personally arrived to show them their tanks and began hinting at a mission that left Captura alarmed.

• Kiel ordered every company to conquer nearby worlds independently while following the Thirty-One Rule and calling for aid against targets beyond their strength.
• Kiel told Captura to wait for Nuceria Prime’s people, who would upgrade the 37th Company’s equipment and assign it enough recruits to form at least two hundred tank crews.
• Captura inspected the 37th Company’s recruits and kept silent when Kharn teased him and brought the second batch’s champion gladiators to the Eighth Company.
• Qin Xa led the 37th Company through the White Knight’s maintenance bay and showed Captura its new anti-gravity tanks and upgraded crimson Shadowsword, Fairblade.
• When Captura asked why Qin Xa had come personally, Qin Xa smiled, and Captura realized the Guide seemed to be proposing something inappropriate.

Qin Xa led the 37th Armored Company in Fairblade to conquer a steel-covered world, enjoying his first chance to command a Shadowsword Tank. After the locals surrendered and called him a butcher, a Gunship bearing the emblem of the 13th Legion arrived.

• Qin Xa toured Fairblade and commanded it as the 37th Armored Company advanced toward the planet’s largest city.

• A Gunship marked with the Roman numeral thirteen descended from a warship that did not belong to the 12th Legion.

Qin Xa’s forces claimed a world for the 12th Legion while the Ultramarines’ Nemesis Chapter arrived and massacred civilians. Qin Xa forced the Nemesis officer to concede the world and began gathering the local leaders, while the 12th Legion’s shortage of warships remained clear.

• Qin Xa recognized the arriving Space Marines as the Ultramarines’ Twenty-Second Chapter, the Nemesis Chapter, after they began killing civilians.
• Qin Xa raised a Psychic Barrier to protect the civilians, and the Nemesis officer claimed the world for the Thirteenth Legion’s Fifth Company.
• Qin Xa rejected the Nemesis claim and insisted that the 12th Legion could not surrender the world, while Captura threatened the Ultramarines with the armored force’s weapons.
• Qin Xa taunted the Nemesis officer until the officer agreed to leave the world to the 12th Legion, though he maintained that the Thirteenth Legion’s claim was justified.
• Qin Xa ordered the local leaders to gather representatives from the other cities, and a Space Marine remarked that the Nemesis had a warship despite being only one chapter.

• A Space Marine reported that the Thirteenth Legion’s flagship had appeared at the system’s Mandeville Point, and Qin Xa, Angron, and the Archon left to greet it.

Roboute Guilliman arrived on Nuceria and met Angron and Qin Xa, then privately decided to offer Angron a steel planet while hoping to build goodwill and share the pressure facing Ultramar.

Guilliman discussed Nuceria’s violent past and the need for education with Angron and Qin Xa, then tried to lighten the mood by inviting them to play an ancient real-time strategy game. The three entered the virtual war game, but the chapter ended while it was still loading.

• Guilliman, Angron, and Qin Xa discussed the Arena, Nuceria’s history, and the brutal destruction of the High-Riders and Praetorian Guard.
• Guilliman argued that Nuceria’s ancient power structure had prevented negotiation, while Angron and Qin Xa agreed that education was needed to change its citizens’ habits.

• Angron explained that Nuceria used similar devices to treat mental illness, though excessive use could cause reality disintegration.
• Guilliman, Angron, and Qin Xa entered the customizable war game, and its loading bar began to fill.

Angron, Guilliman, and Qin Xa began a simulated fleet battle, with Qin Xa’s psychic power affecting the force-generation device and Angron sensing Guilliman’s thoughts. Angron abandoned strategic counterplay and ordered a direct charge at Guilliman’s fleet, leaving Guilliman to prepare for the assault.

• The device generated the Legions’ forces, and Qin Xa used his psychic power to spawn and then dismiss a vast number of White Knight Librarians.
• The game announced the players, then placed their fleets near the Mandeville Point, where Angron saw that Guilliman’s fleet greatly outnumbered the 12th Legion’s.
• Angron sensed Guilliman’s plans and used that intelligence to destroy a Frigate Guilliman had sent toward an asteroid belt.
• Guilliman tried to mask his thoughts with misleading ideas, but Angron realized he should stop matching Guilliman’s strategic strength and instead use the 12th Legion’s assault doctrine.
• Angron ordered all ships to charge, and Guilliman began preparing for the incoming attack.

The Twelfth Legion’s assault broke through the Thirteenth Legion’s defenses, and Angron led the fight to Guilliman aboard the Macragge’s Glory. Angron and Qin Xa won the battle, while Guilliman’s defeat left the virtual conflict at an end.

• Guilliman ordered the Thirteenth Legion fleet to concentrate fire on the Resolute Determination, but an ancient Void Shield protected it as the Twelfth Legion closed in.

Angron, Qin Xa, and Guilliman played repeated fleet battles, until Guilliman adapted his strategy and defeated Angron and Qin Xa. Afterward, Guilliman urged Angron to rely on his ability to unite his brothers rather than trying to master every skill himself, though Qin Xa doubted Angron would follow that advice.

• Angron and Qin Xa challenged Guilliman in repeated war games, while Angron struggled with the simulated deaths of the Gladiators.
• Guilliman adjusted his defenses across several matches, and Angron recognized that the 12th Legion lacked the resources to carry out many tactics he wanted to use.
• Guilliman delayed the battle, encircled the 12th Legion, and used attacks on the Resolute Determination and a trap aboard the Macragge's Honour to eliminate Qin Xa and Angron.
• Guilliman won the final match, and Angron praised his strategic skill.
• Guilliman told Angron that his gift was uniting exceptional people and that he should seek help from brothers such as Perturabo instead of forcing himself to master everything.

Guilliman and Angron discussed the Imperial War Council, the 12th Legion’s limited investment in it, and the possibility that a future institution might pressure their worlds. They agreed that Ultramar and Nuceria would cooperate, and the chapter ended with the three men raising a toast to their alliance.

• Guilliman asked Angron whether the 12th Legion had chosen a representative for the Imperial War Council, and Angron said Kiel had arranged one at random.
• Angron explained that his adoptive father expected the War Council to be replaced, and Qin Xa argued that its unclear purpose made it seem temporary.
• Guilliman agreed that the War Council’s role was vague and urged Angron to stand with him if a successor institution threatened Ultramar and Nuceria.

• Guilliman offered the 12th Legion ships, weapons, and equipment, but Angron declined the aid.
• Guilliman, Angron, and Qin Xa clinked their goblets in a toast.

Angron considered how to secure enough warships for the expanding World Eaters Legion after Nuceria Prime reported its limited production. Kiel proposed seizing a passing Mechanicus fleet, but Angron rejected the plan and insisted on a fair exchange for supplies while promising to find another way to obtain ships.

• A Nuceria Prime representative reported that the planet had built twelve transport vessels and seven Cruisers and would continue producing weapons and equipment according to Angron’s plan.
• Angron and Kiel discussed the Legion’s urgent need for more warships and the Mechanicus’ fragmented factions and difficult relationship with the 12th Legion.
• Kiel advised against trading technology with the Mechanicus and proposed taking the fleet passing through the Nuceria system, which was carrying ships to the Luna Wolves.
• Angron rejected Kiel’s plan and ordered that the Mechanicus fleet receive supplies only in exchange for equivalent payment, not be seized.
• Angron told Kiel that he would find another way to obtain warships and explained how his adoptive father and Oenomaus had taught him to act morally.

Qin Xa ordered Kiel to watch the Mechanicus fleet, trade with it if possible, and seize it if evidence of espionage emerged. After Kiel arrested the fleet on suspicion of infiltration and an assassination attempt, he learned that its leader was Kelbo Hal, the Fabricator-General of Mars, leaving the confrontation poised for escalation.

• Qin Xa told Kiel to offer the Mechanicus supplies and useful technology in exchange for ships, but to arrest the fleet if it committed espionage.
• The Mechanicus fleet arrived at Nuceria Prime, resupplied without incident, rejected nonessential trade, and prepared to depart.
• Qin Xa ordered Kiel to execute Plan Two, and Brown revealed more than twenty disguised mechanical infiltrators before Qin Xa ordered that the fleet not leave the system.
• Kiel and his Space Marines teleported onto the lead ship, accused its crew of espionage and an attempt to assassinate the primarch's adoptive father, and forced the fleet to halt.
• Kelbo Hal, the Fabricator-General of Mars, invoked Article Twenty-Two of the Olympia Compact and warned Kiel that the larger Martian fleet could destroy the 12th Legion's warships.

Angron and Kiel confronted Fabricator-General Kelbo Hal over the Mechanicus's attack on Nuceria and demanded that he submit to an investigation. Kelbo accepted arrest while framing it as humiliation, and the Mechanicus personnel photographed the event as Kharn imagined the news spreading.

• Kiel accused the Mechanicus of attempting to assassinate Angron's foster father and prepared to attack after the Magos dismissed his charges.
• Angron and Qin Xa arrived, and Qin Xa showed evidence that the Mechanicus automata had attacked him and killed a sailor aboard the White Knight.
• Angron rejected the Magos's defense and demanded that Kelbo and the Mechanicus personnel submit to detention and interrogation or face a fight.
• Kelbo stepped out from among the automata and submitted to arrest, telling his followers to endure the humiliation.
• Kiel shackled Kelbo as Mechanicus personnel took photographs and Kharn imagined the arrest becoming news.

Qin Xa reflected on the coming conflict after Kelbo’s arrest and brought Quadrant to meet his former mentor. The meeting revealed that Quadrant had once been a gifted apprentice named Ilka, while Kelbo claimed Angron’s perception could not fully see him.

• Qin Xa told Angron that he had sought the Mechanicus warships, but argued that their fleet’s infiltration justified arresting Kelbo.
• Angron warned Qin Xa that his gift seemed unable to perceive Kelbo completely, while Qin Xa agreed to take Quadrant to visit him.
• At the security headquarters, Zeth and Cain respectfully performed the Gear Rite for Quadrant and confirmed that Kelbo was inside.
• Quadrant entered the interrogation room, and Kelbo identified him as Ilka, his former apprentice, and criticized his choices and augmentations.

Qin Xa confronted Kelbo over his treatment of Quadrant, whose memories revealed both the cruelty and kindness in their past. Qin Xa realized Kelbo had come to Nuceria seeking a private conversation to win over the 12th Legion, and Kelbo proposed bringing Angron into negotiations.

• Qin Xa rebuked Kelbo for insulting Quadrant and reminded him that he was a prisoner, while Quadrant explained that Kelbo's signed order had led him to believe he was exiled.
• Quadrant recalled his childhood in a Martian factory, where Kelbo discovered his handmade breathing filter and took him away to provide education and a better life.
• Quadrant remembered both his gratitude toward Kelbo and his hatred of the crude surgery Kelbo later performed on him, while Kelbo continued to insult him.
• Qin Xa struck Kelbo after Kelbo recounted defending Quadrant, and Kelbo admitted he had mainly been venting his resentment toward his apprentice.
• Qin Xa deduced that Kelbo had come to Nuceria to persuade the 12th Legion to join the Mechanicus, and Kelbo asked to negotiate with Qin Xa and Angron.

Qin Xa and Kelbo Hal argued over whether the Emperor was a fraudulent prophet, with Qin Xa explaining why he would oppose the Emperor in some matters but still cooperate to avert humanity’s destruction. Kelbo remained unconvinced, trusting his Golden Age artifacts’ visions of a future under the Emperor’s tyranny over Qin Xa’s account of the coming crisis.

• Kelbo Hal told Qin Xa a story that retold the Emperor’s arrival on Mars and asked whether its prophet was a fraud.
• Qin Xa said people facing an impending catastrophe might believe the prophet or cooperate with him until the crisis was resolved, while most people might not even know the danger existed.
• Kelbo dismissed the crisis as a threat the prophet used to make people submit, and Qin Xa abandoned any attempt to persuade him.
• Qin Xa admitted he would cooperate with the Emperor to avert humanity’s destruction while opposing him on other matters, and said his fear came from witnessing future horrors.
• Kelbo considered whether Qin Xa came from the future, then rejected the idea and trusted his artifacts’ visions of the Emperor’s tyranny instead.
