This cavern is filled with many different types of crystals.
During the Burning Legion's third invasion, the Doomhammer fell into the cavern, and the area was entered by the demon Geth'xun and his imps. They also corrupted its inhabitants and killed several Stonehearth Prospectors. The Earthen Ring, searching for the Doomhammer and Geth'xun, defeated the demons and claimed the Doomhammer.
