Mokkan was a Marlfox, the eldest son of Silth and the brother of Lantur, Ziral, Gelltor, Predak, Vannan, and Ascrod. As he was known to be the cleverest of his siblings, he unofficially appointed himself their leader (as such, Redwall Friend & Foe counts him as the primary villain of Marlfox), though he was often paired with Ziral during raids. Mokkan also planned many of the attacks on Redwall Abbey and successfully stole the tapestry of Martin the Warrior.
