The Moon of Tenacity, also known simply as Tenacity, was the eponymous planetoid in the Tenacity system. During the Last Great Time War, it was the location of a Gallifreyan Military Moon Base, run by Commandant Harlan. The Eighth Doctor was taken to the planetoid after his capture by Cardinal Ollistra on a planet. Following an attack by the Daleks, (AUDIO: The Conscript) the base was evacuated by the Time Lords, with the Ollistra, Bliss, Quarren and Rupa Maguire, escaping with the Doctor in his TARDIS.
