You create a shimmering doorway to a room created by the original caster. The room can very in size but maxes out at 500 square feet. Any non-living material can be added to the space. Any living material will be ejected into the Material Plane once the spell ends.

Anything non-living material left in the room once the door is shut will be transferred to the Ethereal Plane until summoned again with the ritual.

If the item used to create this portal is destroyed the contents will be scattered throughout the Ethereal Plane.

If the spell is used to create another Vault the first Vault will dispel and scatter it's contents through the Ethereal Plane
