Lok'Tar Ogar!

Ku'Zog Chieftain of the Blood Monger Clan
Orcs of the Blood Monger clan have developed growing white hair over the generations, due to their custom of consuming the blood of their slain on their sacred ritual after successful skirmishes, they return to camp with blood soaked hair and bring it back to be pooled on a cup made from the skull of the chief or leader of the defeated enemies.
