King Ad Rak Cthoros was the bulky, grim-faced King of the Murgos/King of Cthol Murgos at the time of the Battle of Vo Mimbre. He was the last king of the Cthan dynasty. He was slain in the battle with an Ulgo knife in his belly, and his sword was kept by his house, the House of Cthan, until it was given by the then-Princess Prala to King Urgit.
