Duat

Duat is the sole dimension of Egyptian mythology.

Mythological background
Duat is an underworld, described as not only the place where the dead go upon death, but also as the place where the sun, personified as the god Ra, travels every night. Geographically, it is described as being divided in twelve regions or chambers, each closed off by a gate guarded by a powerful deity. It was also said to have a river flowing through it, from west to east through all the twelve regions. The twelve regions represent the twelve hours of nighttime, and the river represent the sun's passage through the night, as the sun god Ra is depicted as traveling on a barge, and the river of Duat starts where the sun disappears at dusk and ends where the sun appears at dawn.

The general Egyptian conception of the afterlife was that the souls would have to traverse a long and perilous journey filled with trials and dangerous creatures. In that way, the Egyptian afterlife was extremely unequal. Egyptians would bury their dead with various objects like food, amulets, spells, guidebooks and maps, which would facilitate their passage through Duat. That meant that your chances in the underworld were proportionate to how much you invested in you burial.

The dead would have to pass the twelve gates, each guarded by an invincible snake deity who would only let souls pass if they recited their names. The rich were therefore usually buried with a list of all the gatekeeper's names.

The dead who survived the journey would be judged by fourty-two judges and permitted into the Fields of Reeds: paradise. Those who were considered unworthy of paradise had their souls devoured by Ammit. The ancient Egyptians had no conception of a punitive hell like the likes of Abrahamic religions, they believed that the worse hell imaginable was for one's consciousness to cease to exist.

Duat is ruled by the god Osiris
