Gallifrey

Gallifrey (/ˈɡælɪfreɪ/) is a fictional planet in the long-running British science fiction television series Doctor Who. It is the original home world of the Time Lords, the civilisation to which the protagonist, the Doctor belongs. It is located in a binary star system 250 million light years from Earth. It was first shown in The War Games (1969) during the Second Doctor's trial, though it was not identified by name until The Time Warrior (1973–74). In the revived series (2005 onwards), Gallifrey was originally referred to as having been destroyed in the Time War, which was fought between the Time Lords and the Daleks. It was depicted in a flashback in "The Sound of Drums" (2007) and appeared prominently in "The End of Time" (2009–10). At the conclusion of "The Day of the Doctor" (2013), Gallifrey is revealed to have actually survived the Time War, though it was frozen in time and transported into a bubble universe, before being unfrozen and arriving at the end of the universe at a chronological point before "Hell Bent" (2015). By "Spyfall" (2020), it had been reduced to ruin by The Master who described the planet as hiding in its bubble universe again. At the end of "The Timeless Children" (2020), one of the Doctor's allies, Ko Sharmus, detonates the "Death Particle" on Gallifrey, wiping out all organic life on the planet, the Master and his army of Cyber-Masters presumably included. The points in time when Gallifrey appears are never definitively stated. As the planet is often reached by means of time travel, its relative present could conceivably exist almost anywhere in the Earth's past or future, as well as anywhere in the conceivable universe.
