As you spend 1 minute to cast this spell, you create a door on a flat solid surface that you can see within 10 meters. The door is large enough to allow Medium creatures to pass through unhindered. When opened, the door leads to a demiplane that appears to be an empty room 5 meters in each dimension. The plane is generally flat and featureless, such as an earth, stone, water, or wood floor. The plane is filled with air or water (decided by you). The “walls” and “ceiling” of the plane may appear like solid earth, stone, wood, or water, or they may end in mist, a featureless void, or a similar unreal-looking border. The plane’s environmental conditions are those of a temperate spring day on the Material Plane. You determine the plane’s light level (bright, normal, dim, or darkness), which affects the entire plane.

There are no native creatures or plants on this plane, though you may bring some there (if the plane’s light is bright or normal, it counts as sunlight for growing plants). The environment of the plane counts as normal terrain for the purpose of effects that target earth, stone, wood, and so on. For example, you could use mold earth to create a small trench or fabricate to create a stone building.

Creatures can only enter the plane by the use of planar travel spells such as plane shift. You are considered “very familiar” with your entire demiplane.

When the spell ends, the door disappears, and any creatures or objects inside the demiplane remain trapped there, as the door also disappears from the other side.

Each time you cast this spell, you can create a new demiplane, or have the door connect to a demiplane you created with a previous casting of this spell. Additionally, if you know the nature and contents of a demiplane created by a casting of this spell by another creature, you can have the door connect to its demiplane instead.
