A demiplane is a Plane of existence that is newly formed and far from completion. Unlike planes, which can have many planets, creatures, and even "levels" consisting of separate existences that are connected together, demiplanes are much more restricted in their scope. Demiplanes can be as small as a single house or as large as a planet, though the latter is incredibly rare to find and usually means the God controlling the demiplane is almost strong enough to creating an actual plane. Demiplanes can also have living creatures in them. These creatures are usually designed by the owner of the demiplane to serve a certain purpose, though some opt to create for fun or even bring creatures from another plane to populate theirs.
