The world of the Pharaonic cosmology is bounded by the realms of Order and Chaos. To the west of the mortal world, where the sun sets every night, lie the fair Offering Fields (Seket-Hetep) where the souls of the righteous live in eternal reward. Under the earth, where the sun (steered by Ra/Khepri) passes each night in struggle with the forces of evil, are the Twelve Hours of Night. Demons, serpentine monsters, and the souls of those who died without proper funerals populate this dark underworld. Together, the Offering Fields, the Twelve Hours of Night, and the heavenly arc of the sun's daylight journey compose Duat, the otherworld in Pharaonic cosmology.
Although the worshipers of the Pharaonic deities view Duat as a single realm of existence, it is actually three distinct Outer Planes where most of the deities of the Pharaonic pantheon reside.
