View source for Bulrath, the Butcher

After Prigdenia fell in 65 YSK, the slaves who freed themselves split into two factions; the group that traveled for thirty years to eventually establish Thryddmalk, and a barbarous group that settled outside of the Rusted City. These barbarians lived a rough life there for nearly 200 years, before Bulrath the Butcher led them to war. 

Bulrath was an exceptionally large and cruel orc. He had been raised among the barbarians and trained in the arts of battle since he was born. It is said before he reached maturity, he was gifted a magical axe from Nelroth, which he earned in combat. This magical axe was called the Knight Cleaver, and in Bulrath's capable hands, it lived up to its name. He slayed nearly half of the Knights of Xarnath before meeting his end at the hands of the good king J'aramé Iron, who slew him at Godspire.
