- Phoebe: Yes, we do. It coexists within our own plane. Remember, that’s what Stevie said.
The Astral Plane is a plane of existence that coexists with the physical plane. However, time does not move forward in this plane.
Abraxas was a demon who resided in the astral plane. He managed to steal the Book of Shadows from the Charmed Ones by pulling it into the astral plane. By casting a Power of Three spell as one, they managed to retrieve the book and vanquish Abraxas.
