[Source] This mystical stone was an object with inexplicable powers that was given to an adventurer by the Tulgah Echrhin Isdan in 1.5 ABY. It was a white, smooth stone that could glow eerily. When this adventurer visited the village of the Myyydril tribe in the Myyydril Caverns, he met the Tulgah Echrhin Isdan. Isdan asked the adventurer to collect smooth stones from the river and pond outside the cave. As a reward for bringing him the stones, Isdan gave the adventurer this smooth stone and told him that it provided a quick way to get out of the caverns.
