Thostír the Rank

Thostír the Rank is a fire dragon, one of the famed “Ring-drakes”, having consumed the dwarven ring Tulcya. It is said that Thostír may be the dragon who laid waste to Dwarf-kingdoms in the eastern mountains in times of old. Thostír was captured by the Weeping Warrior and thrown into The Abyss of Mordath, imprisoned within Glúrghash, the Pit of Flame. He escaped when Sauron fell, and his prison was rent asunder. Thostír has not been seen since - perhaps he has returned to his ancient roosts in the far northeast?
