Mendox Cataclysm
From Warhammer 40k - Lexicanum
The Mendox Cataclysm was a war between the Imperium and the forces of Khorne, which spread across entire star systems. During the Thirteenth Black Crusade though, the forces of Khorne were victorious after they destroyed eighty-eight of the Imperium's worlds at once.[1]
Upon completion of this genocidal ritual, the Blood God's champions were assailed with visions of their patron raging against Roboute Guilliman's return. They then waged battle against one another to earn the right to hunt down the Primarch.[1]
