A deepe is a type of setting in the Metal Shadow universe. Deepes are floating spheres often large enough to contain a city. They somehow produce skylight, a veil over the natural sky that repels beastie. It is thanks to deepes that humanity survived the Wilderness Era and continue to thrive in Gilta Nnea today.
Many deepes open up via means of a gravitational platform embedded in its surface. Mankind has developed means of entering deepes through these platform openings.
Networks of deepes are called Skies. Skies now represent the nations of the land.
