Riven is one of the original four Specialists. Initially an uncooperative loner, he has since become a more amiable member of the team. He specializes in resourcefulness and stealth, and is a skilled fighter. Riven is the impulsive, competitive, realistic and goal-oriented member of the Specialists. He can be rather hot-headed, experiencing moments of envy and blind aggression; but he is also protective and caring. Riven has trouble expressing his emotions in a suitable manner, even when he is not putting up a cold front. This often leads to him clashing with Musa.
