The Lake of Apparitions was a lake that existed in a realm of the Force known as beyond shadows. Any being who walked across the Lake had to step carefully, or they would sink into the Depths of Eternity, from which they couldn't be saved. While walking across it the spirits of deceased Force-sensitives could be seen on the surface of the water, known as the Mirror of Remembrance. Over the Lake hung heavy mists, which were known as the Mists of Forgetfulness.
