Arc 48Gungnir’s Black Sphere
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.
