The Duat is the ancient Egyptian realm of the dead, a mystical place where souls journey after death. It is often depicted as a dark, complex landscape filled with rivers, mountains, and various challenges. The Book of the Dead, a collection of spells and prayers, served as a guide for the deceased, helping them navigate this afterlife and achieve eternal peace. In the Duat, the soul encounters various gods and creatures, including Osiris, the god of the afterlife, who judges the deceased. Successful navigation through the Duat leads to a peaceful existence in the Field of Reeds, a paradise where the soul can live forever in harmony.
