Astral Plane
The Astral Plane is the great silvery sky that connects all planes to one another, the realm of pure thought and expanded consciousness. Occasional islands of solid matter float in astral space, but most of the plane is an enormous, seemingly eternal void of silver radiance. As a gateway between the Inner and Outer Spheres, the Astral Plane teems with travelers, from entities venturing between planes to explorers searching for one of the numerous demiplanes secreted here or looking for the one of the countless marooned spirits that dwell within the expanse. Its nature as a crossroads makes the Astral Plane very dangerous. Although it’s possible to visit the plane bodily via plane shift or by using an item such as a robe of stars, most travelers prefer to play it safe by manifesting their souls in an astral body created by spells such as astral projection.
A creature’s astral body looks like a translucent version of its physical form, usually limned with a soft nimbus of blue or violet light. A slim tether of resilient incorporeal energy known as a silver cord connects a creature’s astral body to its unconscious physical body. If the astral body dies, the silver cord retracts into the physical body, returning the soul to its familiar seat (albeit at the cost of two permanent negative levels due to the resultant trauma). A silver cord resists most attempts to damage it, but if it somehow manages to break, the creature immediately dies, and the astral form housing its soul is cast adrift on the astral currents, pulled inexorably toward the enormous spire of the Boneyard, which extends up into the Astral Plane from the surface of the Outer Sphere. As a realm of thought, the Astral Plane is home to entities that represent concepts, myths, and legends spawned from mortal thoughtforms. Mediums open their consciousness to these denizens of the Astral Plane, inviting them to reside in a physical form and spread their influence on the Material Plane.
Travel through the Astral Plane is a strange affair, as the plane’s subjective directional gravity means that each traveler chooses the direction of gravity’s pull. Creatures can move normally in any direction by imagining “down” near their feet and “falling” in that direction. In this way a creature “falls” 150 feet the first round and 300 feet on each successive round. Movement is straight-line only. A character can attempt a DC 16 Wisdom check to set a new direction of gravity or stop as a free action; this check can be attempted once per round. Any character who fails this Wisdom check on successive rounds receives a +6 bonus on subsequent checks until he succeeds. When moving in this manner, the traveler does not have the sensation of physical movement. Rather, the landscape of the Astral Plane (such as it is) seems to come toward, through, and past him. Scintillations of light are thrown off by the astral body as it moves along at great speed.
The untethered astral bodies of the dead flow toward the Boneyard along the River of Souls. During this process, the dross of mortality is shed, leaving behind only the soul’s core self, its memories, and the refined character of its prior life. The gods of the Outer Sphere consider the River of Souls inviolate, often sending celestial and infernal outsiders to help steward wayward souls toward judgment and eventual delivery to their afterlife of reward or punishment. Soul-collecting or soul-devouring predators such as night hags and astradaemons prey on the dead of the Astral Plane, usually limiting themselves to picking off isolated incorporeal undead but all too often raiding parties of disembodied souls as they make their way toward eternity. Pharasma, the goddess of the dead, hates this perversion of the natural order of the multiverse, and the entities known as psychopomps often act as guides to deliver souls safely to their final destinations.
Other inhabitants of the Astral Plane include enormous astral leviathans that float through the silvery seas, sometimes with passengers or even semi-permanent settlements upon their backs; strange caulborn who harvest knowledge and psychic energy from astral travelers; formless nirmanakaya manasaputras who seek to guide Material Plane adepts through telepathy; and the lean humanoid outsiders known as the shulsaga, multiplanar hunters who ride magical disks and view intruders to their astral realm with xenophobic disdain.
Geography
Upon entering the Astral plane, travelers saw a silvery color pool nearby—a portal to the location on the Prime Material plane from which they originated. Astral projecting travelers saw their silver cord leading back to this pool. Color pools appeared as two-dimensional circles about 10‒60 ft (3‒18 m) in diameter and only visible from one side unless they had some way to detect invisible objects. Pools of different colors were portals to the different Outer planes. Each Outer plane had its own unique color, but the traveler's home portal was always a metallic silver, rippling like mercury in a pan. Color pools could be used to view the destination plane before stepping through by mentally concentrating on the nearby pool until it became transparent. A viewer could also move (with some limitations) the portal's viewpoint by concentration. Astral projecting travelers formed a new physical body (with silver cord attached) when they stepped through a color pool to their destination plane. The new body was formed out of local materials so the greater the similarity between one's home plane and the destination, the more one's new body looked like the original one.
