This is where souls are judged after their bodies die in the Physical Realm. The God Hades goes through all the paperwork describing the deeds they have done during their lives and sends them down one of the three Duat paths: Heaven, Limbo, or Hell. If the dead fail to pass the challenges presented to them on whatever path they are put on, they will be instantly transported to Limbo. If they fail the challenges on the Hell path, they will literally go straight to Hell. Unlike a lot of other areas in the Nether Realm, there is no way to get here without being dead.
