# Om · the Great God in a tortoise's shell

Om is a Great God of the Disc, and in *Small Gods* he discovers a humbling truth: the belief that once made him mighty has dwindled almost to nothing. So little faith remains that he is trapped in the body of a one-eyed tortoise, scrabbling along the ground far below the heights a Great God expects to occupy. A god runs on belief, and his has nearly run out.

What keeps Om from vanishing entirely is a single true believer: Brutha, a slow, kind novice. Through Brutha, Om learns the lesson at the center of Pratchett's theology — that gods are made and sustained by the belief of people, and that a god who forgets the people who believe in him becomes nothing at all. The power flows upward, from the faithful to the divine, and Om has spent too long imagining it ran the other way.

From the bottom of the food chain, peering out of one eye at a world he used to look down on, Om learns humility. The journey from thunderous deity to small reptile is also a journey toward understanding what a god owes to those who make him real.

His nature of emergence is spiritual: Om is not machinery and not merely an abstraction, but a being of belief and the soul-deep bond between a god and his people. He exists exactly as far as faith allows, which is why his story belongs to the realm of gods, belief, and the things that are kept alive by the human heart.
