But in short, it is a void like plane where things can can only exist as mental summaries of their existence (ie. as thoughts and concepts) due to the lack of even a single dimension in which matter can exist. Because of this there is also no concept of "direction" in that void and one will just randomly start appearing in subsequent nearby locations when they move. If a non-sentient object is not observed, accounted for, or otherwise expected to exist by a sentient entity that also enters non-dimensional space at around the same time, it will cease to exist. Likewise, should a sentient entity fall unconscious or leave without taking the object with them, it will also cease to exist.

Huh, this is pretty cool. I wonder how Arthur's powers of imagination might fit with this, if I can build something off of it. We'll have to brainstorm some time. Clarifying questions:

1. Is there such thing as a "subsequent nearby location" in a place without direction? How can people "observe" a non-sentient object?
2. Does an unconscious sentient entity cease to exist, or is it the non-sentient entities that it apprehends?
