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 Shekra the snake is holy and to kill a snake is a mortal sin. If a snake slithers into the cities or to the streets, Zuul’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. Shekra 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.
