Alvin pressured Drakris into secretly deploying the Dominator Overlord Titan and offered him control of a Forge World in exchange for joining his cause. Drakris pledged himself to Alvin as Forge Grand Sage of Transformers planet B_258 and accepted a dangerous mission supporting the Blood Angels and Dark Angels at Dragon Forest Star.

• Drakris accused Alvin of forcing him to deploy the Dominator Overlord, while Alvin argued that their deal had given him authority to use it.

• Drakris pledged obedience to His Highness Alvin and accepted the mission.

Alvin recognized Drakris’s defection as a path to Mechanicus technology and planned to use him to gain influence over Styx Eight. As the Lion El'Jonson took command of the battle, he coordinated the forces and ordered a plasma strike on the Iron Warriors’ position in Sector D-30.

• Aurelian ordered the Dominator Overlord’s Plasma Incinerator Cannon to charge while the Iron Warriors and an enemy Chaos Titan prepared to attack.

Angron led the World Eaters through a breach in the Imperial line and attacked the Dominator Overlord before advancing toward Lion El'Jonson's command Sanctum. The Lion revealed that he had lured Angron into a kill zone, where Alvin appeared with more than a hundred Chaos Battleships and sent them crashing down on the Chaos forces.

• Angron emerged with the World Eaters and exploited the breach left by the Knight Legion's charge, while a Chaos Titan engaged the Dominator Overlord.

• Vashtor recognized Alvin and asked what terms he would offer in exchange for betraying Chaos.

Alvin met Vashtor in his prison and negotiated over the damage he had caused at Nomad Port. Vashtor demanded a fragment of the Void Dragon, Magradros, leaving Alvin stunned by the Tech Daemon’s true price.

• Alvin studied Vashtor’s nature and ambitions, recalling that the Daemon sought the Key and that one fragment was hidden in the Rock Fortress.

• Alvin asked Vashtor for advance compensation, and Vashtor agreed to cause a one-day technical malfunction among the Khorne Legion on Dragon Forest Star.

• Alvin urged Guilliman to focus on routing the enemy and avoid escalating the war, arguing that Khorne must not be weakened too severely.
• Guilliman stopped the official recording and ordered Inquisitor Beckett to keep the conversation secret before allowing Alvin to continue.
• Alvin explained that the other Chaos Gods could exploit Khorne’s weakness, provoking a conflict that might draw in the Necrons and other alien forces.

• Abaddon questioned how Guilliman had amassed so many troops and ships after dividing his forces.

Abaddon realized Guilliman had assembled a vast fleet and could not be stopped by the Warp trap in the Idolater System. Guilliman’s forces destroyed the Black Legion’s blocking fleet in half an hour, leaving Abaddon furious as the Imperial Fleet advanced.

• Abaddon recognized that Guilliman’s fleet was powerful despite being only part of the Indomitable Crusade and feared what Guilliman could gather with more time.
