A planet where the Stargate is contained within a simple room constructed by the Ancients. There are no doors or windows visible in the surrounding darkness, and the floor is decorated with a gold ring of text in an Ancient dialect: Noo ani anqueetas ("We are the Ancients"), hic qua videeum ("the place of our legacy").
On a wall in the corner of this chamber is the first known repository of knowledge. It is unclear where the power to run the lights is located, or what lies beyond this chamber.
