Angron defeated Fulgrim in battle as Horus and Ferrus Manus prepared for the assault on Terra, while the Iron Hands ravaged Ultramar. Nur’s virus crippled the Iron Hands’ mechanical network and opened the way for Guilliman, Sanguinius, and Lion El'Jonson to attack, as Ferrus Manus prepared to face them.

• Angron shrugged off Fulgrim’s poison and anesthetic, battered him, and crushed his skull before ordering Skolzne to hunt down the retreating Emperor’s Children.
• Horus ordered Ferrus Manus to leave Ultramar and join the assault on Terra, while Ferrus left Shadrak Meduson in charge of the Pharos and a mechanical duplicate.
• The Iron Hands destroyed Ultramarines fleets and conquered most of the Five Hundred Worlds, forcing Marius Gage to defend Macragge with dwindling forces.
• Charlie’s squad escaped the ruins of Constantine Satellite with a captured drone, and Nur proposed using a virus to disrupt the Iron Hands’ constructs.
• Nur joined Valentus Dolor’s boarding party and infiltrated the Node Warship while Gage committed his remaining fleet to Macragge’s defense.
• Valentus fought Talosis as Nur reached the Node Warship’s control room and uploaded the virus, which spread through the fleet’s network even after Talosis killed him.
• The virus disabled the Iron Hands’ drones and constructs, and the fleets of Guilliman, Sanguinius, and Lion El'Jonson broke through the enemy defenses.
• Ferrus Manus activated Clone No. 1, ordered Fulgrim to keep holding Angron off, and boarded an assault barge to confront the three Primarchs.

Guilliman rallied the surviving loyalist forces in Ultramar as Sanguinius and Angron defeated Ferrus Manus, who was then transformed by Zahurash. The loyalists regrouped at the Fortress of Hera and prepared to continue the war without Lorgar's forces, while Lion pursued the White Scars and Guilliman named the campaign the shadow crusade.

• Guilliman learned that the Iron Hands had invaded Ultramar and ordered his fleet to relieve Macragge, while Lion El'Jonson offered to pursue Ferrus Manus with Sanguinius.
• Jaghatai Khan lured Lion El'Jonson into pursuing the White Scars, while Sanguinius remained to face Ferrus Manus's enormous war machine.
• Guilliman retook Macragge, found Lady Euten alive beneath the Fortress of Hera, and returned to the front.
• Sanguinius fought Ferrus Manus's replicas, then drew the second replica to a death world where Angron arrived and joined the battle.
• Angron and Sanguinius defeated Ferrus Manus, and Angron agreed to fight alongside Sanguinius in Ultramar while he waited to learn Lorgar's condition.
• Zahurash confronted Ferrus Manus beneath the Sotha Beacon, destroyed his mechanical backpack, and rebuilt it with silver light and reality-warping power.
• Vashtorr withdrew from intervening in Ferrus Manus's transformation and turned his attention to other potential targets, including Vulkan and Corax.
• Guilliman, Sanguinius, Angron, and Lion El'Jonson regrouped at the Fortress of Hera, then Guilliman sent Sanguinius to Konor, Angron to Nuceria, and named the campaign the shadow crusade.

Lorgar’s crusade and Mortarion’s Death Guard converged on Bakka as the Loyalists fought off Horus’s fleet. Corax’s bargain with Vashtorr brought a corrupted Raven Guard Legion into the war, and the arc ended with Lorgar confronting Be’lakor as Corax attacked him.

• Jaghatai failed to uncover Lion El'Jonson's defenses, then joined Fulgrim and Ferrus Manus at the Pharos to receive new tasks.
• Word Bearers forces and allied soldiers fought daemons on Pagnis as Lorgar’s crusade liberated worlds and gathered fleets.
• Lorgar ordered the Chapters in Segmentum Tempestus to defend Bakka, while Mortarion accepted Horus’s order to attack it despite his doubts and lack of warships.
• Amg led his Orks through the Webway and emerged on the War of the Webway battlefield, where he rallied them against the daemons.
• Biberus and the 616 Chapter reached Bakka and pledged to defend it, while Corax accepted Vashtorr’s offer to resurrect the Raven Guard in exchange for the Word Bearers’ Blackstone Fortress.
• Corax used the Host of the Departed to raise a grotesque, daemon-infused Raven Guard Legion and joined Mortarion’s advance on Bakka, while Horus’s forces sacrificed billions to disrupt the Loyalist fleet.
• Cestus and the 616 Chapter helped defend Bakka as the Traitor fleet attacked, and Harald led a Space Wolves assault aboard the Herald of Destruction before Corax killed him.
• The Word Bearers arrived to strike the Traitor fleet’s flank as Corax’s warriors attacked the fortress, and Lorgar confronted Be’lakor aboard the Shadow of the Emperor, and Corax attacked Lorgar from behind.

Lorgar defeated Corax at Bakka as Mortarion’s shifting loyalties and Horus’s wider campaign reshaped the war. Meanwhile, Zorge’s stolen intelligence revealed Gungnir’s planet-destroying power, setting Abaddon, Omega, and Leman Russ on a collision course over the weapon. The arc ended as the Space Wolves prepared to board Gungnir.

• Lorgar battered Corax through the Shadow of the Emperor and banished him to the Warp after their battle on a volcanic planet, while Mortarion arrived at Bakka, killed Naberius and Storas, then withdrew after settling his debt to Lorgar.
• Lorgar ordered the Word Bearers to avoid the Death Guard and began conscripting the Millennium Worlds, while Horus used Bakka as a feint for a fleet strike elsewhere.
• Corax regenerated in the Warp and claimed Lorgar as his prey, while Ferrus Manus offered to deal with Lorgar and questioned Corax’s ability to defeat him alone.
• Zorge infiltrated Gungnir, stole its plans, and escaped aboard a waste transport, but his infected wound weakened him before a Word Bearers fleet found his ship.
• Abaddon consumed Zorge’s brain and learned Gungnir’s location, prompting Lorgar to send him reinforcements and call on Leman Russ to reach the weapon.
• Alpharius assigned Omega to defend Gungnir under the guise of a Loyalist Primarch, while Utio test-fired the weapon and destroyed a Forge World and nearby planets with its black sphere.
• Utio chose Holy Terra as Gungnir’s next target, so Omega and Abaddon moved against each other as Abaddon’s forces prepared to board the weapon.
• Omega fought Abaddon aboard his flagship and revealed a face identical to Alpharius’s, then turned toward the arriving Space Wolves as Abaddon ordered his companions to support Leman Russ’s boarding assault.
