Brother Carfin was a member of the Synod of Stygg, a group of mages, witches, and warlocks opposed to the rule of the Lady in the Lands of Fist. He was described as a skeletally tall narrow-limbed man with pale skin and long black hair. He lived in a cave, to which he referred as his "subterranean domicile" and claimed he was not technically a eunuch. Carfin wore a dark shirt, vest, and trousers, each notable for their patchwork of mending. Carfin was a mage of Rashan.
