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) from 8 June 1980. (WC: 14682 UNIT Field Log) The Doctor admitted to being frightened by the Fracture, which had the makings of an "infinite temporal collapse". (PROSE: Hello And Congratulations!)

History
The Fracture was created (PROSE: What the TARDIS thought of "Time Lord Victorious") in 2059 when the Tenth Doctor declared himself Time Lord Victorious and changed history by saving Adelaide Brooke on Mars and returning her home to Davies Street. (TV: The Waters of Mars) The Doctor's TARDIS watched as "a paradox was born" upon her stepping onto the street, widening into the Fracture. As the TARDIS had anticipated, (PROSE: What the TARDIS thought of "Time Lord Victorious") the Doctor used the Fracture to access the Dark Times after Adelaide's suicide, arriving on the planet Andalia. (PROSE: The Knight, The Fool and The Dead)

Another belief was that the Fracture appeared during 1942 (WC: Tia Kofi Enters the Time Fracture!) caused by a Luftwaffe bomb, but potentially something more sinister than that. The bomb supposedly detonated, but instead of a typical explosion, the entire building went missing, and in its place was simply the Fracture. (PROSE: Welcome to Operation Time Fracture) Doctor Errol Courtney claimed this was the case. (WC: Tia Kofi Enters the Time Fracture!)

The Fracture spread out through time, (PROSE: What the TARDIS thought of "Time Lord Victorious") such as Central London, (WC: 14683 UNIT Field Log) where UNIT began observing one of the transdimensional portals on 8 June 1980. (WC: 14682 UNIT Field Log)

The Doctor believed that Anke's collection of impossible items in the Verbier Museum of the Impossible was a result of people manipulating the Time Fracture forming. He pleaded with her to give the items to him as they were dangerous enough separate, but together they would be even worse and allow something to come through, but she refused to yield.

Robert Dudley was one of the UNIT workers examining the Fracture and was sent in to find out more, but he went missing. (WC: 14683 UNIT Field Log) He ended up on the planet Khan where he was successfully nursed back to the health and went through another Fracture wherein he ended up in Elizabethan England. (WC: This is Sergeant Robert Dudley.) He continued to report to the UNIT black site, stating that there was a mysterious agent was jumping through the Fracture to collect various parts for something. (WC: Is anyone receiving these transmissions?)

The Doctor realised that the Fracture could potentially destroy the universe, but reasoned that UNIT were doing a good job of containing it, and that "parking" a complex space-time event like the TARDIS next to the Fracture might make the problem worse rather than better. Between this logic and their own fear of it, they avoided trying to interfere with the Fracture. (PROSE: Hello And Congratulations!) The Doctor nonetheless provided UNIT with a list of names of people who could help in "Operation Time Fracture". UNIT established the Portal Stabilisation Gateway to allow those the Doctor named through it. (WC: Tia Kofi Enters the Time Fracture!)

Tia Kofi was one of the names provided by the Doctor to assist with the crisis. She appeared the UNIT black site and met up with Errol Courtney. He briefed her on the causation of the Time Fracture. He then guided her into the Portal Stabilisation Gateway and once in she encounters William Shakespeare in Elizabethan England. He tells her that he will be her apprentice and referred to himself as Tia Kofi II. He invites her into his office wherein he explains that Queen Elizabeth I has commissioned a play for him to write called Romeo and Juliet. Tia Kofi volunteered to play Juliet with Shakespeare donning the role of Romeo before the Time Fracture sent her elsewhere. She met a courtier. Mid conversation he expressed confusion as to how there can be multiple queens but Tia explains that where she lives in Clapham there are many queens there. She states she wants to meet Elizabeth I but the courtier believes she wouldn't want to meet her right now. Noticing there is potential gossip, and the courtier conceding that Tia is royalty, he begins to explain before they're interrupted by the sudden appearance of a Cyberman. The two run away before the Time Fracture takes Tia to the Queen. While Elizabeth is initially happy to meet Tia, a series of increasingly offensive questions. Tia is interrupted by a clearing of the throat, reminding her she is supposed to be saving the universe and as she runs off Elizabeth orders for her to be executed as Tia leaves.

A human explorer became trapped in a time loop after entering the Time Fracture, remaining trapped for 20000 subjective years reliving the same adventure over and over. During their repeating adventure, the explorer discovered a darkness behind Zaggit Zagoo, found out the secrets of Zoria, and listened to "the wrong ghost" on Gallifrey. On their millionth go-around, the Doctor managed to get a message through to them, congratulating them for their resilience and promising that the final loop might be close in their sights. As "something" had been moving through the Fracture, trying to get out, and was making the Fracture exponentially more dangerous in the process, causing it to suck more and more of the universe into itself, the Doctor was beginning to think the time would soon come when they should enter the fray themself.

Behind the scenes
Although appearing in other parts of the Time Lord Victorious storyline, the Time Fracture was primarily featured in the interactive stage play of the same name. There, they explained that the Time Fracture was actually created by the detonation of a bomb called the Temporal Disruptor. This was part of the Time Lord Zoria's plan to destroy the universe so the Time Lords could rebuild it in their own image and become rulers, as this would ensure her family's survival.
