Mortilus

Mortilus the Traitor; Mortilus the backstabber. Mortilus was created by the universe in response to The One's needs. Although he fought on the side of Paladin in the war against the Dark One, at the end he turned against his leader and stabbed him in the back, releasing the Dark One in the process. Unlike the others that sided with the Dark One, the fate of Mortilus was unclear, although history believes that The One banished him to some distant pit where he would burn forever as vengeance for his son.
