The offspring of the demon released by the Heirs of Menonias, Ákrah are dangerous beings that had been used by Menonias as thieves, assassins, and spies in the years leading up to and during the wars for which he became the namesake.  His heir, Traddeon, took up his father's habit of using Ákrah for the same purposes.  In Book I:  The Heirs of Menonias, an Ákrah was used to spy on the Chosen Warriors (Amara, Asher, and Gavin) and when it had an opportunity, it attempted to kill Asher because the Cadásur were the mortal enemies of the creature's mother.
