For instance, in ancient Egyptian mythology, the god Osiris is considered the keeper of the underworld, also known as the Duat. After Osiris' resurrection, he became the ruler and judge of the dead, presiding over the weighing of the hearts of deceased individuals to determine their worthiness for eternal life.
Similarly, in Greek mythology, Hades is the keeper of the underworld, referred to as the "House of Hades" or the "Realm of the Dead." Hades governs over the souls of the deceased and prevents them from escaping.
In Norse mythology, the goddess Hel, daughter of Loki, rules over the underworld called Helheim. Hel reigns over the realm and determines the fate of those who enter her domain.
These are just a few examples of how different mythologies depict the fate of the keeper of the underworld. In each case, the keeper's role is paramount in maintaining the order and balance of the afterlife within the respective mythology.
