Inner Sanctum

This spell seals a 20-foot sphere or a single room of like size against scrying, psionics, and magical entry (teleport, dimension door, and so on). It allows no access to or from other planes or dimensions. If not cast in an enclosed area, the sanctum area not only blends into the surroundings, but subtly affects the senses of creatures around it so that not only is it not detected, but creatures subconsciously avoid entering the warded area. The caster can, at will, allow others to see and enter the sanctum. The caster can see his or her own sanctum. The spell boundaries are not solid and do not prevent the entry of physical material, such as rain.
