Midir, Lord of the Underworld

Midir is a reclusive bronze dragon who spends all its time deep within the umbral mazes of the underdark. He rarely makes any effort to bother with surface affairs and prefers to stay out of sight and out of mind. It is said that many decades ago Midir and Hyltades used to be staunch rivals in the depths, fighting time and time again until Hyltades chose to seek power on the surface instead.
