The Xindi Council planet was the home to the Xindi Council. Its location was top-secret, and the planet was located inside a security zone. The planet was located approximately fifty light years from the Sol system. The Council chambers were located in a fortress built into a mountainside by the Xindi-Avians sometime in the 2nd millennium BC. The fortress was two kilometers above ground level and was perfectly concealed by the cloud layer that surrounded it. The only way in was through the air.
