Lord Dheolur was the head of the Dheolur noble house of Cormyr. He married Threena Cormaeril. His sister was Pella Dheolur. He wore a suit of black chased and fluted plate armor with a helm, from Chondath, and bore a long slightly curved blade. In 432 DR, Dheolur was killed by King Duar Obarskyr after his house had defected against Cormyr to side with Magrath the Minotaur. Duar severed Dheolur's head from his body with the sword Orbyn.
