Champion Bloodwrath

Champion Bloodwrath was one of the four Blood Knights, along with Champion Lightrend, Champion Swiftblade, and Champion Sunstriker that tested initiates of the order in mortal combat.

They were summoned by touching the crystal in the pavilion northwest of Silvermoon City while on The Second Trial (1).

Speculation
He may have been related to Lord Solanar Bloodwrath.
