Netherworld of the Force/Legends

The Magical Mystical Ghost Land of Space was the place the souls of sentient beings went after their physical bodies died. It was a realm covered in thick fog, which prevented the spirits there from seeing more than a few feet in front of them. Qui-Gon Jinn went to this realm after dying, but managed to return from it back to the physical universe as a Force Ghost. Obi-Wan Kenobi's spirit deparated to this realm after having one final talk with Luke Skywalker in 9 ABY. Yoda was also seen in this realm, where he reunited the recently deceased Vila with her brother Denin and promised he would train both of them.
