The Otherworld

Beliefs in the afterlife gave birth to the Underworld or Paradise. They exist in a different universe/world but they are indeed true: places where spirits depart to. There are some Paradises where the gods reside. Valhalla and Mount Olympus are considered as part of the Otherworld. Hell (in Christian beliefs) and other derivations of the underworld also have their own places.

The Otherworld is considered as where most empowered humans get their powers, be it a blessing from a god, a curse from a demon, a deal with the Devil, or an Otherworldian artifact they got. Experts believe that they exist parallel to each other instead if being crammed in one world. The way of getting to the Otherworld varies from myth to myth.
