The Krell sorceress is an alien resident of a Krell who has placed Princess Malocoti under a spell, trapping her in the form of a giant red dragon. Under this spell, Malocoti cannot attack the sorceress, but also cannot speak to tell anyone who she is.
She remains with Malocoti at the tower on Krell until the Paladins arrive and Lance recognizes the dragon's enraged behavior to be the same as Allura's when she is angry with him. The Paladins realize they have mistaken the sorceress as the princess and battle her. Malocoti is freed from the spell when the sorceress is defeated. The exact fate of the sorceress afterward is unknown.
