Dimension Stable

The caster creates a dimensional door access to a storage area for living creatures.  Anyone the caster deems access can place or remove items from the storage area.  The size and weight of an object do not hinder the space. After the duration has expired or the caster moves farther than 50 feet from the space, the door dissipates and the caster has to recast this again to gain access to the space.  Any living entity in the space, remains sealed in the space except the caster.  The caster resumes its actions at the point of original casting.  If a creature can teleport, they can leave the space but the space remains removed from all other dimensions.  A DC of 15 + INT Arcana check can find hidden dimension stables.
