Arc 8Horus’s Last Stand and Ember’s Rise
Horus saved Vigilus, defeated Abaddon, and died from an assassin’s spear, leaving Guilliman with his technology and Fulgrim as Warmaster of Imperium Nihilus. Reborn as an Avatar of Khaine, Liu Zhipeng saved Biel-Tan and led the Ember Guard toward Iyanden as the Tyranids overwhelmed it.
- Horus defeated Angron and Mortarion, then led his fleet to Vigilus and rallied its defenders against Orks, Chaos, Genestealers, and Drukhari.
- Horus destroyed the Crawling Patriarch and Kroodaka, while his allies routed the Drukhari and drove back the other threats to Vigilus.
- Horus accepted Abaddon’s challenge, killed him, and then was fatally wounded by a hidden Cabal assassin’s spear.
- Horus entrusted Cawl with a technology chip, sent his loyal warriors to Calgar, and disintegrated, and Perturabo later killed Katavonus as the Black Legion withdrew.
- Guilliman gave Fulgrim the task of serving as Warmaster of Imperium Nihilus, while Liu Zhipeng’s sixth life ended and his seventh began on Biel-Tan.
- Liu Zhipeng took control of the Avatar of Khaine, became Ember, saved Biel-Tan from Slaanesh’s daemons, and formed the Ember Guard from its awakened spirits.
- Ember proposed uniting the Aeldari and working with humanity, then led the Ember Guard through the Webway toward Tyranid-overrun Iyanden.
- A Tyranid Hive Tyrant killed Iyanden’s Avatar of Khaine, and Khaelmon ordered the Heart of Fire activated despite warnings that it would destroy the Craftworld and its Infinity Circuit.
