Vyrokan
From Warhammer 40k - Lexicanum
Vyrokan the Sullied is a winged Daemon Prince of Tzeentch.[1b]
History
He led his forces of Daemon Engines, Cultists, Plague Marines and a significant number of the Thousand Sons in attacking the Imperium city Valmar Magna and reduced it to ruins. However a Dark Angels task force, led by the Chief Librarian Ezekiel and aided by the Freeblade Knight Gerantius appeared and fought Vyrokan to reclaim the city. In the fierce battle that followed, the Daemon Prince's forces inflicted significant losses to the Dark Angels, but they were defeated and Vyrokan was banished back to the Warp.[1a]
