Gallifrey

Gallifrey was the homeworld of the Time Lords. Conflicting accounts on its fate in the Last Great Time War existed. By one account, it was destroyed when the War Doctor used the Moment to engulf it and seal the event inside a time lock. However, according to most accounts, it was only believed to have been destroyed in the Last Great Time War because it was actually frozen in a pocket universe by at least thirteen incarnations of the Doctor and later discovered at the end of the universe.
