(Assuming Draco approves), the Stargate would be located in the Television Section. It is a prop from the television series Stargate SG-1, and it basically involves a device creating a wormhole to a like device that allows for instantaneous travel to any planet, as long as you dial the correct "address". The Stargate universe has thousands of habitable planets (and a few now inhospitables), a small number of which have been seen in the show. I would imagine, if Sarah came through the Stargate at some point, she might have come from a more advanced civilization and encountered some sort of issue or encounter which lead to her amnesia.
