Time Fracture

The Time Fracture was a time anomaly and transdimensional portal which was located and observed at a former UNIT Black Site, located at coordinates 51°30'47.7"N 0°08'51.9"W. (WC: 14681 UNIT Field Log, 14682 UNIT Field Log, 14683 UNIT Field Log, 14684 UNIT Field Log)

The Fracture was created in 2059 when the Tenth Doctor changed history by saving Adelaide Brooke on Mars and returning her home to Davies Street. His TARDIS watched as “a paradox was born” upon her stepping onto the street, widening into the Fracture. The Fracture then spread out through time.

As the TARDIS had anticipated, (PROSE: What the TARDIS Thought of “Time Lord Victorious”) after Adelaide’s suicide the Doctor used the Fracture to access the Dark Times, arriving on the planet Andalia. (PROSE: The Knight, The Fool and The Dead)
