Sector 8

Sector 8 of the Capitol was home to the Time Travel Capsule landing bays and an array of repair shops. Below the repair shops was an area known as the TARDIS Graveyards, where TARDISes that reached the end of their lifespans were despatched. Somewhere in the citadel, a set of chambers were allocated to the Celestial Intervention Agency, but no one outside the Agency knew exactly where those chambers were. Deep beneath the Panopticon were the Panopticon Vaults, where the Eye of Harmony was kept. (PROSE: A Brief History of Time Lords)
