Mr. Mordaut is a character from the game RuneScape. He is a a feral red dragon who is unusually intelligent compared to other dragons in the game - one of the very few dragons that can speak to the player. He prefers to actively avoid combat and has more intellectual persuits - running a class, working for the museum, and overseeing archeological digs. He wears glasses and is almost always sat at his desk.

He fills a similar role in Old School RuneScape, though his design differs slightly, mostly in the shape and features of his head: in RS3 he has 2 horns and many backward-facing spines, whereas in OSRS he has 3 horns and a frill connecting the spines.
