The Demon Lord Mordja was known in Morindland and was also seen in Darshiva. He had three blazing eyes and a vast muzzle filled with great fangs and had huge clawed feet. He towered over elephants and was described as big as a barn and was enormously powerful. He had a dozen or more snakelike arms that writhed and lashed at the air. He had vast enmity with the Demon Lord Nahaz.
Mordja eventually took on the form of the dragon and took on Torak's sword, Cthrek Goru. At the high places of the Korim, Cyradis bound Mordja to that form, and Garion and party slew the dragon (and assumably Mordja as well) but not before Mordja killed Toth.
