Mount Thunderstone was an active volcano on the Forest Moon of Endor. A dark and forbidding place, Thunderstone was home to Morag, the Tulgah witch, who lived in a castle in the mountain until her death in 3 ABY. The area was under constant surveillance by Yuzzum guards, many of them mounted in rakazzak beasts.
