Estate Transference

This powerful spell allows a caster to transfer a large area of land in the Prime Material plane to any of the elemental planes. All buildings, people, and wildlife within the area of effect are also transported. The land forms a pocket of the Prime Material plane within the elemental plane.

The pocket is a 5-mile-radius sphere that fully contains the land. The surface of the pocket allows creatures to enter or exit the pocket, but prevents the elements from entering the pocket. Inside the pocket, the land is surrounded by air of a temperature matching that of the Prime Material plane at the moment the land was moved. In addition, a source of water is created within the pocket.

Before the spell is cast, the area to be moved must be surrounded by solid markers of material from the destination plane. Thus, if a wizard wants to move their castle to the Elemental Plane of Fire, they must first surround the area with solid blocks of matter from the Elemental Plane of Fire; such as hardened magma or magically-crystallized fire. The blocks must be spaced no more than five feet apart and may be placed above ground or under the surface (at a depth of no more than three feet).

The caster must be within the area to be moved when the spell is cast. When the land moves, a hemispherical crater is left behind in the Prime Material plane. Inside its pocket on the desired plane, the land continues its existence as if nothing changed, with the exception of occasional visits from planar creatures.

Any land that is moved in this manner can never again be moved with this spell.
