Arc 37The Void Dragon Conquest
The clone primarchs returned to the Imperium, Guilliman destroyed the Cabal and recovered its artificial Perpetual technology, and Lox subdued the Void Dragon’s essence on Mars. The Imperium celebrated its new alliances, but the effort to gather the remaining C’tan shards threatened to draw humanity into conflict with Imotekh’s Sautekh Dynasty.
- Rylanor sacrificed himself to destroy Fulgrim on Isstvan III, and Clone Fulgrim embraced loyalty, defeated his original self, and helped the clone primarchs banish him with the God-Emperor’s power.
- The clone primarchs returned to Terra, where Clone Horus accepted Horus’s surviving soul fragment and Guilliman gathered a force to rescue Lady Yottun and seize the Cabal’s immortality research.
- Guilliman’s seers manipulated the Cabal’s visions to lure its hive ship to Kassa Octavius III, where the Imperial forces attacked and John Grammaticus and Damon Prytanis returned to humanity’s side.
- Guilliman secured the artificial Perpetual technology, but Omegon escaped with hidden Cabal assets after killing Youhai and Slau Dha.
- Neoth and Lox persuaded Szarekh to support using C’tan power to reinforce reality, and Lox prepared to seize control of Mag'ladroth beneath Mars.
- With Dantioch’s aid and the Blackstone array amplifying his power, Lox erased the Void Dragon’s will while preserving its essence, then returned to Terra with the purified fragment.
- The Emperor hosted a celebration where Tarasha Euten reunited with Guilliman and his clone, and Szarekh agreed to transfer other Mag'ladroth shards in exchange for Lox’s records.
- Trazyn warned Guilliman that the largest remaining shard belonged to Imotekh’s Sautekh Dynasty near the Five Hundred Worlds, and Lox accused Szarekh of leaving humanity to confront Imotekh.
