Dheolur was a former noble house of Cormyr. One of its houses was situated beyond the Royal Gardens in Suzail, Cormyr, and another in the King's Forest, protected by a 20 foot high (6.1m) wall, built on top of the ruins of a temple of Moander. The house was elevated to nobility by the grandfather of King Duar Obarskyr. When Magrath the Minotaur seized control of Suzail around 429 DR, the house swore fealty to him almost immediately.
