Ootopyllidro

The Moon of Marvels, Ootopyllidro is a the largest construct in the ten realms. The entirety of the moons structure is mechanical clockwork. The Automatons who live among its labyrinthian tunnels revere the moon as the greatest of their kind. With religious reverence they maintain the clockwork, and each other raising the longest lived automatons to high religious positions among their brass churches.
