From Warhammer 40k - Lexicanum
Ravenwing Champions are the Company Champion of the Dark Angels Chapter's Ravenwing Company.
Those chosen to become the Ravenwing's Champion, are gifted a deadly Blade of Caliban - an ancient power sword as old as the Chapter itself. Wielding this weapon, the Ravenwing Champions are called upon to defend the 2nd Company's honor during ritual combat, and tasked with cutting down their most formidable opponents.
