The Astral Plane is, quite literally, the plane of stars. More precisely, it is where the stars and portals to the heavens reside—an infinitely vast celestial void that surrounds all the worlds of the Material Plane.

The Astral Sea, like Wildspace, is a void; however, it is not an airless one. Here, you can breathe normally and exist indefinitely, never aging and never needing food or drink. You can propel yourself through the Astral Sea with the power of your mind alone, though many astral voyagers wisely travel in well-armed ships, for this place is the home of a host of fearsome creatures. Here travelers might find the petrified hulks of dead gods and swirling pools of color that serve as portals to other planes of existence.
