The sixth series of "Gallifrey" features the Daleks invading Gallifrey, but this invasion was undone thanks to Romana, Leela, K9 and Narvin, aided by Romana's future self. The ninth series more directly featured the Time War with Romana and Leela playing key roles, including Leela being sent on a mission with the Derek Jacobi Master, Irving Braxiatel taking Ace on a mission to test her ability to fight in the War, and the resurrection of Rassilon through a complex Time Lord project that allowed Rassilon's consciousness to take over the body of another Time Lord.
