Arc 37The Fall of Prospero
Lorgar raced to Prospero to stop Magnus’s Grand Spell, only to find himself caught in Tzeentch’s schemes and drawn into a battle that helped destroy much of the Webway. As Lorgar was taken to Colchis to recover, Horus began purging prisoners aboard the Vengeful Spirit, and Abaddon led a breakout.
- Lorgar learned that Horus was gathering rebel Primarchs, then fought through Sothaviel’s time-bending Labyrinth and reached Prospero after three weeks had passed.
- Lorgar confronted Magnus atop Prospero’s Pyramid, but Tzeentch’s illusion and manipulation delayed him while Magnus’s Grand Spell disrupted the Imperium’s Warp routes.
- Lorgar joined the fighting on Prospero, killed Thousand Sons defenders, and pursued Magnus’s soul toward the Webway gate to Terra.
- The Emperor empowered Lorgar to oppose Magnus and Tzeentch, but Alpharius’s use of the Tyrant Star distracted the Emperor and helped Tzeentch overwhelm them.
- Lorgar fell gravely wounded as the Tyrant Star’s power broke through the Emperor’s Webway barrier, destroying passages though most personnel had been evacuated and roughly half the Webway remained intact.
- Angron and Curze found Lorgar on Prospero, and Curze followed the Emperor’s instruction to take him to Colchis.
- Horus ordered the Cleansing Plan aboard the Vengeful Spirit, targeting the Word Bearers and imprisoned warriors who had questioned him.
- Abaddon, Torgaddon, and Loken broke the prisoners out of the Brig, and Kaebo warned Abaddon that Horus had betrayed the Imperium and begun a purge.
