Morag's primary base, a sizable castle, was situated high above Mount Thunderstone which itself was on Endor's forest moon. The Tulgah witch, Morag, had it defended by Yuzzum sentries, who were dedicated to her. This lair served Morag as the central location from which she launched numerous assaults on her hated adversaries, the Ewoks. In the climactic battle between Morag and Logray, the Shaman, Morag obliterated her own base using the power of the Sunstar, causing her fortress to be engulfed by Mount Thunderstone's lava.
