Astral Sea

''It is the space between everything.

It is the road that goes everywhere.

It is where you are when you aren't anywhere else.''

Geography

The Astral Sea could be reached from almost any point in a Material plane by spell, psionic ability, or device. It was described as a barren place of other-dimensional nothingness extending in all directions. What little solid substance that floated in the bright, gray void was typically chunks of matter broken off from their original plane. The Astral had no gravity but objects did retain their mass so you could throw small items or push off from large objects to move in the weightless environment.

Time in the Astral flowed at the same rate on a Material plane but the effects of time were slowed down significantly―a year in the Astral Sea felt like only a day to the traveler.

Entering the Astral Sea could be accomplished in one of two ways: projecting your astral form into the plane via the astral projection spell, or by physically entering the plane. Astral projection was the safest way to travel but still involved risk because you left your physical body behind on the traveler's plane of origin. The astral body would be accompanied by the astral forms of any items and clothing that were magical or radiated a magic aura. While projecting, your astral self was connected to your physical body by a silver cord that stretched out behind you for about 10 ft (3 m), or 1 ft (30 cm) depending on the version of the spell, and then became invisible and intangible. Luckely, this cord is very strong. even for giant it would be quite a challenge to rip this cord.

The physical body left behind appeared alive but did not require food, water, or air and did not age.[6] It could be moved and was vulnerable to damage and death. If the traveler's physical body was slain, death followed the projection some minutes later. If the astral self was slain, the traveler then returned to his or her physical body in a coma. Physically entering the Astral Sea required a spell such as plane shift and brought the traveler wholly into the Astral with no silver cord to anchor her to her plane of origin. Emotions and thought can become reality here, creating possibility's and new danger for this place.

Geographical Features

The Astral Sea is unlike the name suggests, not fysicaly a sea, but more remenicant of Limbo for it's chaotic nature. The sky here is everbright but sunless, matter of all planes scatter the place.
