After Afafrenfere was freed, Drizzt and Entreri swiftly made their way to Gauntlgrym’s mines (in order) to rescue Ambergris, while the others remained in the forge room. Shortly thereafter, Catti-brie received a magical call from the primordial and was drawn to the primordial chamber, where the godlike beast unsuccessfully tried to persuade her to free it. Catti-brie was soon attacked by a water elemental that had been commanded to guard the chamber, but she ultimately managed to destroy the creature.
