Brouver Hoog, a dwarven elder, is the real authority in Mahakam. He resides at Mount Carbon. He is known for his traditional and conservative view but he exercised his authority justly. He decreed that dwarven youths were not to join the Scoia'tael. His popularity was not universal though and many considered his authority too restrictive and at times quite controversial.
In particular, Zoltan Chivay expressed nothing short of contempt for Brouver and his policies.
In the standalone adaptation of gwent card game, there is a leader card of Scoia'tael deck that bears his image and name.
