Gallifrey is the umbrella title of a line of audio plays set in the Doctor Who universe, produced by Big Finish Productions, featuring Louise Jameson as Leela, Lalla Ward as President Romana II, and John Leeson as two K-9 units, Mark I and Mark II. The title refers to the home planet of the Time Lords.
The first play in the series, Weapon of Choice, was released in 2004. The most recent: Gallifrey: Intervention Earth, was released in 2015.
The series focuses on political struggles within the leadership of the Time Lords, centred on Romana's presidency. In the first series, Romana's progressive policies and desires to open Gallifrey up to the outside universe faces opposition from more conservative cultures. In addition, a terrorist group known as "Free Time", who want to break the monopoly on time travel technology shared among the Time Lords and the few other temporal powers, steals a timeonic fusion device. The inquiry into Romana's handling of the incident reveals a dark secret surrounding the Time Lords' policy of non-intervention.
The second series sees the admission of non-Gallifreyans into the Time Lord Academy, leading to even more tension within the Time Lord political elite. Romana has to deal with Free Time infiltrators as well as an attempted coup by Inquisitor Darkel. In addition, an ancient Gallifreyan evil escapes from the Matrix: Pandora, a megalomaniacal personality who manipulates Romana and others with the goal of regaining life and power. At the end of the second series, Pandora manages to manifest herself in the form of Romana's first incarnation (played once again by Mary Tamm). Both Romanas claim the title of Imperiatrix, absolute ruler of Gallifrey, leading to civil war.
