Mac Mordain Cadal is a dwarven mine south of LaMut, dug into the Grey Towers. In ancient times it was inhabited by a dragon worshipped by the kobolds. When the dragon disappeared the kobolds accused the Dwarves. Their leader Feydhir underook a holy quest to find the dragon, and in that they stirred a Brak Nurr, which collapsed the main passage killing 30 dwarves. They put a reward for anyone who would manage to defeat the monster, but all failed.
