Based on the Dungeons and Dragons 5th Edition Ravenloft Setting. It has many names. The soul. The life-spirit. In the deserts of Har'Akir, it is called The Ka. It is the essence that inspires life in all beings and brings joy, sadness, and all other feelings that make life real. Above all, it gives the greatest gift - the ability to die. After his many crimes, the gods stripped away the Ka of the cruel Pharaoh Ankhtepot and cursed him to an eternity of undeath. The pharaoh, unable to sate his hunger, quench his thirst, or feel the light of the sun on his face, filled Har'Akir with his undead armies and forced the people's worship towards him. Every being - living, dead, or undead, was driven into a nonstop search for the pharaoh's Ka. Years, millenia, and ages passed. Ankhtepot's fury waned, but never his arrogance. His search for the Ka proved fruitless and many lost faith in his leadership. Alive, but not living, the pharaoh retreated into isolation as his priests continued the search. He covets one thing, and one thing only - death.
