Masul was the son of Balthazar, the greatest leader in the tribe's history, and became herd leader after his father's death. He lived in the town of Balthazar Lair.
The town was flooded during the Night of the Crystal, and Masul and many of his people were trapped by the rising waters. They would likely have drowned if the Hero of Jadame hadn't arrived. The hero opened the town's watertight siege doors, the waters drained away, and the minotaurs were freed. Masul thanked the hero for the rescue, and eagerly accepted an invitation to join the Alliance of Jadame.
