The Netherworld of the Force was the realm the spirits of Force-sensitives and non-force-sensitives can ascend to after their physical bodies died. Part of the Afterlife, the spirits can enter the Netherworld and learn how to come back to the physical universe as Spirits of the Force.
In 32 BBY, Jedi Master Qui-Gon Jinn went to the never-ending realm after he was killed by Darth Maul, but, thanks to the help of the Force Priestesses, he managed to return from it back to the physical universe as a Force Spirit.
