Skullrage

The oldest records of the Empire recall a warband bearing this name, whose helmet were crowned with Khorne's skull rune. The tales told that the Skullrage fought alongside Morkar, the first Everchosen, and for once the tales were true. In the long centuries since, the brutal knights had continued Morkar's battle, refusing to bend their knee to any of the pretenders that came in their master's wake. Only when Archaon rose did the knights of the Skullrage pledge themselves to another's cause, having seen the glory that the thirteenth Everchosen would bring.
