Multiverse



The multiverse was the collective term for every parallel universe. Esterath told the Eighth Doctor that in all his past travels across dimensional planes he had never left his own multiversal realm. Having been allowed to experience the lives as his alternate selves, the Doctor realised that together they comprised one being. (DWM: The Glorious Dead) It was also known as reality, (DW: Journey's End), and creation (DW: The End of Time); the empty spaces between the universes was known as the Void. (DW: Army of Ghosts)

Iris Wildthyme's TARDIS could travel through the multiverse (IW: Wildthyme at Large) and the Axis was capable of allowing an individual to travel through the multiverse via portals that led to different timelines. (BFG: Reborn)

In the final day of the Last Great Time War, Rassilon planned to destroy the whole of creation with the Ultimate Sanction. To escape the destruction of reality, the Time Lords would shed their corporeal bodies and become creatures of consciousness alone, ones that would escape the effects of time and of cause and effect. This plot was foiled by the Doctor who used the Moment to destroy Gallifrey and cause the near-anhiliation of the Time Lords and the Daleks. (DW: The End of Time)

A Cyber-Leader at Stonehenge warned that with total event collapse, "all universes will be deleted", indicating that the phenomenon threatened the whole multiverse. (DW: The Pandorica Opens)
