Planes of Power
The 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 place with only rare bits of solid matter. 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.
Understanding what the Astral is is difficult. Some sage once said, “if the multiverse were a theater, then the Astral plane would be the scaffolding that the scenery was built on.” (Another sage called him an idiot, and all these arguments rage on today about the nature of the Astral.)
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.
Dead gods are here as “god-isle”s. A god-isle is the immense petrified remains of a dead god that 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, although that gravity is subjective to your orientation on the isle.
The Astral plane is often used as a method of travel since it touches every Prime Material plane is existence as well as the first layer of every Outer plane.
A color pool is a type of gate used to move from the Astral to somewhere else. They can only be seen from the Astral and the color tells you the destination plane. Color pools are two dimensional, so they can be difficult to spot or find as one’s perspective needs to be just right to see them.
