Freedom Square

 was the main location on the Sphere of Freedom, frequented by fans of its immersive reality games. It was protected by gamer guards who defended the area from threats to the disruption of its games, which were being used to hold back the Ravagers.

Original timeline
The Ninth Doctor landed in Freedom Square upon tracking down a series of time eddies, which was where he met Nova. They later reconvened there upon trying to stop the eddies, but it failed and Nova was captured by one. Afterwards, the Doctor explained the events to an old woman who he later learnt was Audrey Mohinson, the mastermind behind the eddies. (AUDIO: Sphere of Freedom) Later, the Doctor, Nova, and their allies returned there with a new plan, but it also failed and the Doctor was captured. (AUDIO: Food Fight)

Rebooted timeline
After learning how the time eddies were being used to hold back the Ravagers, the Doctor was able to rewrite his first visit to Freedom Square and stop the Ravagers with Audrey. The square later held a large fireworks display in celebration. (AUDIO: Food Fight)
