Point of Stillness

The Point of Stillness was a place where the Time Lords were forbidden to go. The Fourth Doctor tried to explain to Leela about it and its relation to time travel. The Time Lady Marianna was imprisoned inside the Doctor's TARDIS after attempting to find the Point of Stillness. (AUDIO: The Abandoned)

The Professor and Ace visited the Vespertine Lodge in 2036 in search of the Point of Stillness, which the Professor had heard about from his friends. They discovered that the strange time bubble effect at the Point was actually caused by a time prohibitor, a banned party trick. (AUDIO: Guests for the Night)
