Set God

Set, the old serpent, is the god of the Stygians. Set worship originated with the serpent-people who were driven from the world by King Kull of Valusia, but he rose once again among the ancient races of the south. Players who wish to partake in the ritual sacrifice of hearts, to learn the secrets of snakes and summon a giant serpent as their Avatar should choose Set. Set is the arch-enemy of Mitra
