William Charles Hil'neer, commonly known as Warley, was the student of the elder summoner Harrad U'niviel. He was often frustrated by Harrad's eccentricity but did his best to serve his master in the Magicracy of Alent. He turned out to be the mysterious mage killer and blackmailed the Anti Mage Police into helping him. He was eventually defeated by Harrad and Omaroch d'Zarnagon in Alent.
