Jedi Grand Master Luke Skywalker and son, Jedi Knight Ben Skywalker, traveled to Sinkhole Station in search of the Mind Walkers in 43.5 ABY. The Mind Walkers took them beyond shadows, where eventually they found the Lake of Apparitions. While crossing the lake, Luke stumbled, causing his whole leg to go underwater. When Ben looked to see the cause, he saw his father had stumbled at the sight of Mara Jade Skywalker floating on the surface.
