Astral Plane

The Astral Plane is the plane of thought, memory, and psychic energy; it is where gods go when they die or are forgotten (or, most likely, both). It is a barren, endless expanse with only rare bits of solid matter, filled with a silvery, twinkling light, the occasional astral conduit or wormhole, and other rare travellers. The Astral Plane also features Colour Pools, gateways which lead to the Outer Planes, and the Prime Material Plane. Pools leading to one's home plane are always silver in colour.

The Astral Plane is infinitely vast, and perception here occurs on an astronomical, even godly, scale. To enter, one must either physically enter the plane (via a Plane Shift spell, for example), or spiritually transcend their physical body, and mentally project an astral body into the plane. There is no space or time in the Astral Plane, though both catch up with you when you leave. The souls of the newly dead from the Prime Material Plane pass through here on their way to their afterlives.

The most well-known feature of the Astral Plane is the silver cords of travelers using an astral projection spell. These cords are the lifelines that keep travelers of the plane from becoming lost, stretching all the way back to their physical body at the traveler's point of origin.
