The Murkblood tribe is a tribe of hostile Broken draenei located in the Underbog and Nagrand. Their presence in Coilfang Reservoir along with the naga suggests they are either allies or slaves of Vashj. They are enemies of the Mag'har and the Kurenai. Killing them will yield 2 or 10 Mag'har reputation for Horde players and 2 or 10 Kurenai reputation for Alliance players. They are hostile to both the Alliance and Horde. They are led by Swamplord Musel'ek who rules from the Underbog in Coilfang Reservoir.
