A world ruined by Angels and demons...
Imperilment was a subplane, entirely different from a pocket space.
A pocketspace was a room anchored to a particular plane. It existed within the plane and was operated by the rules within the plane. Only that, it was like having a pocket in a pair of pants.
Thousands of these could be created as long as the individual was capable enough to do it.
A pocket space was that extra sewn-in pocket. This was why it was called a pocket space.
However, a subplane existed as a world of its own. Such places are usually ruled by their own set of rules. Many times, the normally accepted laws of physics are nonexistent or scarce in such worlds.
Other times, those laws have been perverted.
Either way, subspaces were capable of abhorring life. And this one was even blessed with a star, even though it is literally dying.
