Pria is one of two planets in the Pria system with breathable atmospheres. As the planet has a fairly small surface area, there is not much terrain diversity. About 60% of the planet consists of a large ocean, bordered by glaciers to the north and south poles. Grasslands and a few forests lie along the eastern half of the equator, with small deserts to the south. Across the ocean, some swamps lie along the southern glaciers.
