The Astral Plane is a silvery expanse of nothingness found between the planes of existence.

Structure

The Astral Plane touches the Prime Material Plane and the first layers of the various Outer Planes. The Astral Plane is a three-dimensional void without gravity or any objective concept of up and down. Movement is accomplished by thought. Intelligence determines speed.

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 place with only rare bits of solid matter; some creatures, such as the tyrannous githyanki, use the petrified corpses of dead gods as floating fortresses. The Astral Plane is unique in that it is infinitesimal instead of infinite; there is no space or time here, 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 the afterlife or Outer Planes.

The most common 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 the traveler's point of origin.

God-isles

A god-isle is the immense petrified remains of a dead god. God-isles float on the Astral Plane, where githyanki and others often mine them for minerals and build communities on their stony surfaces. Tu'narath, the capital city of the githyanki, is built on the petrified corpse of a dead god known only as "The One in the Void." God-isles often have unusual effects on those nearby, including causing strange dreams of things that happened to the god when it was alive. God-isles are also the only locations on the Astral Plane that are known to possess gravity or normal time flows.

Features and settlements

  • Astral conduits are whirling funnels that connect the Prime Material Plane with the Outer Planes. The souls of the dead use them to travel to their final destinations.
  • Color pools are gateways that lead to the planes the Astral Plane touches, shimmering with various colors.
  • The corpses of dead gods drift slowly through the void like rocky islands. Githyanki sometimes build fortresses and cities on top of them.
