Givrillian
From Warhammer 40k - Lexicanum
Givrillian was a Sergeant of the Soul Drinkers Chapter, commanding the Tactical Squad designated Squad Givrillian.[1a]
Givrillian was one of the Space Marines who followed Sarpedon when he seized control of the Chapter and went renegade. He was blessed by the Architect of Fate in the process, becoming a mutant with six extra eyes.[1b] When the Chapter was guided by the Architect to a Daemon World ruled by the Daemon Prince Ve'meth, Givrillian was part of the Soul Drinkers strike force that made planetfall.[1c] He was killed in the battle against Ve'Meth itself.[1d]
