The astral plane is vast beyond comprehension, it is a realm of thoughts and dreams, where the idle wishes of its residents could become reality. The astral plane permeates the entirety of Orizon’s outer planar geography, connecting the material with the gods and demons.
It is a great silvery sea, the same above and below, with swirling wisps of white and gray streaking among motes of light like distant stars. Most of the Astral Sea is a vast, empty expanse. Visitors occasionally stumble upon the petrified corpse of a dead god or other chunks of rock drifting forever in the silvery void.
Much more commonplace are "color pools", magical pools of colored light that flicker like radiant, spinning coins.
Creatures on the Astral Plane don’t age or suffer from hunger or thirst.
A traveler in the Astral Plane can move by simply thinking about moving, but distance has little meaning. In combat, a creature’s walking speed (in feet) is equal to 3 x its Intelligence score. The smarter a creature is, the easier it can control its movement by act of will.
