Astral

The Astral plane is a place of inchoate dreams and potential. It exists adjacent to virtually every dimension. A skilled traveller of the realms can dip in and out of the Astral plane to quickly move from one dimension to another, though this requires tremendous talent and focus. It is filled with a strange substance called phlogestein, which coaelesces into a sort of matter in response to focus and willpower. Entities that attempt to project themselves into reality convert this into ectoplasm, which is sustained only as long as the entity is physically capable of maintaining their focus and the energy needed to be corporeal. Ectoplasm is chemically inert and electrically neutral, and disintegrates into nothing very rapidly without a consciousness specifically directing it.

The Astral is also known as the Dreamrealm. It is where mortal ideas percolate and where their minds venture when resting. The souls of the departed linger here, as well as strange beasts and creatures of uncertain disposition and ambition. The Astral realm is not overtly hostile to life or mortals. However, there are predatory spirits and rare creatures capable of harming souls and spirits, or even using cracks in the universe to project themselves into reality.

The Astral is on the road to everywhere, and everywhere leads to the Astral.
