In brief, the Ten are all mages who worshiped seemingly Luukos and were involved in a cult of Amasalen. Initially they were actually a "healthy" political force in town, but that changed when power was whiffed under their noses by a serpent messenger.
From March 1999 through December 2002, Thurfel and the other members of the Council (all liches at this point) were the focal point of a major quest.
You see The Firemage Thurfel Morpholik the Wizard.
He appears to be a Halfling.
He appears to be wizened with age. He has blue eyes and pale skin. He has short, amber hair.
He is in good shape.
He is holding a pearlescent abalone sceptre in his right hand and a twisted serpentine staff in his left hand. He is wearing an amber serpent earcuff, a crystal amulet, a small coral shield, a shimmering glaesine orb, some very scorched robes, a singed crabshell pouch, a supple grey leather pouch, and a dark leather satchel clasped with a crimson crab.
