(Alteration)

Range:  0
Components:  V, S, M
Duration:  1 week per level
Casting Time:  1 turn
Area of Effect:  10?10 feet square
Saving Throw:  None

With this spell, the wizard can create an extra-dimensional room (5-foot cube per level) with one side adjacent to an unbroken 10?10 feet square (i.e., one that has no doors, windows, or other such openings). The surface area (which must be touched) now acts as a phase door into the secluded room. The room can be of any shape and size up to the limit of the spell but at least one side must be at least a 10?10 feet area. Thus, the room could be rectangular, pyramidal, hemispherical, etc. The room lasts for 1 week per level of the wizard, or until dispelled.
The wizard may bring any item, materials, etc. as he desires into the room, so long as the object can fit through the phase door and is touched by the wizard (and only by the wizard).
At the end of the spell's duration, anyone or anything still within the room is now trapped in that extradimensional space. escape is only possible through other extraplanar travel. This also occurs when a dispel magic or similar magic is cast against the phase door area.
The phase door itself is detectable by any means available that can detect magical auras, but the room itself can only be contacted through extraplanar means. Spells such as clairvoyance and clairaudience will not detect the extraplanar room but will instead detect whatever was on the other side of the phase door surface.
The material component of this spell is a miniature hollow golden cube of at least two inches.
