Klief
From Warhammer 40k - Lexicanum
Klief was the General of the Volscani Cataphracts when they turned upon the Imperium in the Battle of Tyrok Fields. However, despite the ferocity of their surprise attack, the Imperial forces rallied under the command of General Creed and Klief and the traitorous Volscani Cataphracts were killed.[1]
