Quindosim Chamber is an underground chamber on the planet Dagan. It was built by the Quindosim to hide the Potentia, a Zero Point Module given to them by the Ancients for protection. It remained undiscovered for thousands of years until Major John Sheppard's team was able to discover it and the nine Brotherhood Stones. After solving the puzzle and acquiring the ZPM, it was stolen by Allina. (SGA: "The Brotherhood")
