Set

From WikiAOC

Set, the Old Serpent, is Mitra's arch-enemy, and the ancient god revered and worshiped mainly in Stygia, and is known and worshiped as Damballah in the Black Kingdoms.

He is a cruel, jealous god who demands constant sacrifice from his subjects, and his priests are only too willing to comply as they bring naked virgins screaming to his altar to appease his blood-lust. In Stygia the snake is holy and to kill a snake is a mortal sin. If a snake slithers into the cities or to the streets, Set's subjects will lay prostrate before him, hoping to be found worthy of his bite.

His priests are almost as frightening as the god himself, and they terrify their own people almost as much as they terrify their enemies. Stygia is a theocracy, and the mad and corrupt clergy run the country on fear and wonder, as well as an indiscriminate willingness to sacrifice their own people.
