Mephiston

A figure of awe and reverence among the Blood Angels, Chief Librarian Mephiston carries the will and power of one who has to overcome what no other Blood Angel has. Mephiston has battled through near-death to surmount the Black Rage, the curse that has afflicted the Blood Angels and their successors for millennia. By crossing the Rubicon Primaris, Mephiston has not only demonstrated the Chapter's embrace of their new battle-brothers, but has become more powerful than ever before.
