Free Time were a subversive organisation made up from many different races, including Gallifreyans, humans, Yevnons and the Monan Host. Notable individuals included Nepenthe.
They were a threat to the Temporal Powers and the Time Lords especially. They briefly gained control of a Timonic Fusion Device and threatened to use it on the asylum planet Gryben. It was later revealed that Free Time were being used as a pawn in an even larger scheme to discredit President Romana. (AUDIO: Weapon of Choice)
Free Time espoused the idea that no one power should have authority over time and that it belonged to everyone. (AUDIO: Square One) The Daleks were the real brains behind Free Time and the "big threat" to Gallifrey. (AUDIO: Panacea, Ascension)
