Thauma is the ancestor of Dwarves, and the god of sun, storm, sea, war, and sovereignty. He is called the Master Fashioner, Lord of Sky, Rain, Thunder, Smithing, and Sovereignty, Sun God, and Ancestor of Dwarf-kind. He became the third Regent of Wu-Yu, ushering in the Zhong Yuga.
No less than three major cults hold him as their primary deity: Thauma-Virun, Tathatan, and Thaumatan. Followers of Tathatan claim that he withdrew to the sun to study cosmic law, leaving no current Regent of Wu-Yu. Followers of Thauma-Virun disagree, saying that he did not withdrew but merely changed to his other aspect, which they hold to be the god Viru.
