The Imperium's ancient enemies, the Chaos Legions that have endured since the Horus Heresy, also poured forth from the Eye of Terror in a frenzy of rage and hatred, as the Great Rift opened its gaping maw. The servants of the Black Goat, the Prince of Slaanesh, the chosen of the one true god, Basileus Angron, the Crimson Angel and lord of the Blood Angels, Sanguinius, and Abaddon the Despoiler all hungered to devour the decrepit Imperium. Beyond these dark servants, the survivors of the ancient empire would also begin their path to the revival of the Aeldari, led by the not-yet-awakened God of the Dead and Goddess of Fertility. The green beasts, the Great Devourer, and the Necrons awakened from antiquity joined in the revelry of the Imperium's destruction.
But in this dark age, the Emperor's favored son, the great Roboute Guilliman, had recovered from the wounds of ten thousand years ago. The Supreme King of Caliban, transformed into a crystal sculpture, had also been awakened by his Supreme Queen. But no one knew whether this would be an era in which brothers united to restore the Imperium, or turned against each other and tore it apart. No one could say. May the Imperium endure, and humanity be reborn.
