Champion Sunstriker

Champion Sunstriker was one of the four Blood Knights, along with Champion Bloodwrath, Champion Lightrend, and Champion Swiftblade 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).

He may have been related to Julia Sunstriker, Jesthenis Sunstriker, Dathris Sunstriker, Elisara Sunstriker, and Elathriel Sunstriker.
