Lorthondo, from Ultima VII Part Two
Little is known about Lorthondo save that he, like Teldrono, had risen to power quickly and was wont to conduct unusual research involving the potent magical reagents. At some point, he entered the Mountains of Freedom in search of the rare mineral stoneheart and took up residence within the dungeon, undertaking his dark experiments within the bowels of the former mines.
During the Avatar's sojourn through Freedom, the hero encountered Lorthondo multiple times. Early in the hero's journey through the dungeon, they were witness to the mage transforming one of his servants into a skeletal dragon; later, it was discovered that the final barrier to winning their liberty from Freedom was Lorthondo himself, and the Avatar found it necessary to free the daemon Arcadion in order to best him.
