Rachef

Leader of Rienka. When Keimos is defeated by Izark, Rachef brings Keimos to safety and grants Keimos power, enough to be considered Izark's equal. He has an incredibly dark childhood. He greatly resented his mother and purposefully killed her by pushing her off a flight of stairs. Witnesses to the event believe that it was an accident. Tazasheena reminds him of his mother and therefore, Rachef dislikes her, as well.
