Predak was a Marlfox, the daughter of Silth, and the sister of Mokkan, Lantur, Ziral, Gelltor, Vannan, and Ascrod. She was often paired with Gelltor during raids. Like all the Marlfoxes, she had pale eyes and silver-white mottled fur. She wore a cloak of green and brown.
Predak took part in trying to take over Redwall Abbey and was the sixth Marlfox to die. While trying to escape the final battle, Borrakul, seeking revenge for the death of his brother, Elachim, cornered her on the Abbey battlements and grabbed her by the neck.
When Skipper asked Borrakul about what had happened between the two, the latter looked over the wall and nonchalantly said she had "vanished", indicating that he had tossed Predak down to her death.
