Brass Door Knob

Wondrous Item, rare This worn brass door knob has a dimly glowing letter C on its circular face.
Holding the door knob in the air, as if holding one belonging to a real door, a shimmering door projects in the direction the knob is pointing. Turning the handle and opening the door will reveal a cupboard with 10 shelves. At any one time, 5 shelves can be seen, only being moved by use of a pulley found inside the cupboard.
Each shelf is 4 feet wide, 1.5 feet deep, and has 2 feet of free space above it. A shelf's weight capacity is 100lb's and exceeding this will cause the shelf to disappear, tossing the contents of the shelf on to the floor. Breathing creatures inside the knob can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.
If the Brass Knob is attached to a wall, or a real door, it is inert until removed.
Placing a Brass (Door) Knob inside an extradimensional space created by a bag of holding, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened.
