4-level Conjuration (ritual)
You conjure a door to a 10-foot tall, 5-foot wide, 5-foot deep demiplane capable of holding a variety of items. The demiplane is cupboard with shelving units, that is overall capable of housing a single medium or smaller creature stood within it, as well as up to 200 cubic feet of material. When the door disappears, the objects inside the demiplane remain safe and secure inside and can be found just as they were when the spell ended on a recasting of the spell. Any creature inside the demiplane when the spell ends is teleported just outside of the door, with everything it was wearing and carrying remaining inside the demiplane. You can have multiple instances of this spell, one per crystal talisman acquired and used in conjunction with the spell.
