In Omnian tradition there is a new Prophet every two hundred years. Om was once a Small God, but managed to speak to a shepherd, gained believers (despite the shepherd being stoned to death) and took over from Ur-Gilash as the God of what became Omnia. Omnians believe in a single god, Om, though the Discworld has many gods, including the billions of Small Gods who exist as points of desire searching for believers. The Discworld is flat and is orbited by its sun, but Omnian doctrine says that the world is round and orbits the sun. Omnia is a theocracy based on the Seven Books of the Prophets of Om. In the process, it satirises religious institutions, people, and practices, and the role of religion in political life. It tells the origin of the god Om, and his relations with his prophet, the reformer Brutha. Small Gods is the thirteenth of Terry Pratchett's Discworld novels, published in 1992.
