It is often depicted as a mystical and otherworldly realm, separate from the physical world and accessible through meditation, astral projection, or magical portals.

The Astral Plane is characterized by a lack of physical matter, with only the occasional astral traveler or astral construct visible. The space of the Astral Plane is often described as infinite and endless, with no fixed boundaries or points of reference. It is also said to be a place of pure thought and consciousness, where the mind can roam freely without the limitations of physical form.

In some settings, the Astral Plane is home to powerful beings and entities, such as astral dragons, mind flayers, or the souls of the departed. These entities may be benevolent, malevolent, or indifferent to mortal beings who visit the Astral Plane.

Travelers to the Astral Plane often use astral projection, a technique of separating one's consciousness from one's physical body, to visit the Astral Plane. There, they can explore the realm, interact with other astral travelers or entities, or seek out knowledge or magical artifacts.

Overall, the Astral Plane represents a realm of spiritual and mystical exploration, where the limitations of physical reality are left behind, and the power of thought and consciousness reign supreme.
