The Astral Sea

The cosmos, outer space, or the expanse beyond worlds. The Astral Sea is the empty vacuum between astronomical bodies. The boundaries between a planet's air envelope and The Astral Sea were gradual. As altitude increased, air became increasingly thinner until it was considered vacuum. Most planets did not have an internal atmosphere and were filled with vacuum instead.

The Astral Sea is a mostly airless void, but contains numerous celestial bodies that are in constant motion. It is also home to many creatures that have adapted to and thrive within the emptiness of space. Spelljamming Ships of all kinds sail through the void between worlds, exploring and plying their trade.

Within the depths of the Astral Sea, adventurers can encounter a wide range of creatures and monsters, as well as alien to the Earth-like worlds of the Material Plane. These range from fiendish Space Squids to massive Cosmic Horrors capable of laying siege to entire planets.
