Prince Desmond of House Lannister Targaryen is the heir to the Iron Throne.
Desmond, or "Des," is the first born child of King Damon Lannister and Queen Danae Targaryen, conceived in the Hightower at the end of the War of the False King. He is a sweet and well-behaved boy, though it could be said that the way in which the King has coddled him has made him less mature for his age than other children.
He enjoys hunting, hawking and watching his cousin Tygett Hill tilt. His father forbid him from training at arms for a time, and he began at an age considered somewhat late for such training. He is fond of Ser Benfred Tanner's stories and his two dogs, Mud and Muddy.
