User:MrThermomanPreacher/Rebooted universe (The Big Bang)

The Eleventh Doctor was forced to "reboot" the universe in Big Bang Two after the Total Collapse Event Incident endangered the post-Time War universe, initially cracking it before reducing it to a starless world. The Doctor was assisted by Amy Pond, Rory Williams and River Song, and so the four of them were the only ones known to remember the circumstances of the universe's reboot. (TV: The Big Bang) The Doctor would continue to live in this rebooted universe in further incarnations, including as the Thirteenth Doctor. (PROSE: Dalek Combat Training Manual)

A day to come
During the Last Great Time War, this reality among others was observed as a Matrix extrapolation of the possible future. (PROSE: Dalek Combat Training Manual)

Origin
The Doctor rebooted the universe by using the Pandorica, created by the Alliance to prevent the total event collapse, which they mistakenly believed he was responsible for. Wiring himself into the Pandorica, the Doctor initiated Big Bang Two using its restoration field powered by explosion of the TARDIS, the cause of the total event collapse. Knowing that, by being contained within the Pandorica, he would be erased from existence, the Doctor piloted the Pandorica into the explosion and found his time stream was unravelling as a side-effect. Before skipping the rest of his "rewind" to oblivion, he left a psychic imprint in the mind of Amy Pond to allow her to remember him back into existence.

Amy woke up on the day of her wedding to Rory Williams where she was greeted by her parents Tabetha and Augustus Pond, who had been lost to the cracks before the reboot. Later that day, the Doctor was returned to the restored universe by Amy and attended her reception. Rory regained his memory of the Doctor upon his arrival; he also remembered being "plastic", having been reconstituted into an Auton after having erased by a crack in time before the reboot. (TV: The Big Bang)

Continuity with other versions of reality
River Song, the daughter of Amy and Rory who had been conceived on their wedding night, (TV: A Good Man Goes to War) later encountered the Doctor and Amy at the crash of the Byzantium, before they had experienced the Total Collapse Event. There, she told the Doctor that he would next see her when the Pandorica opened. (TV: Flesh and Stone) "The Pandorica Opens" and the crash of the Byzantium were recorded in River Song's diary which was read by Flemming, who recalled that a movie was made about the latter, aboard the Harmony and Redemption, which was visited by River and the Twelfth Doctor. (TV: The Husbands of River Song)

The New Dalek Paradigm was established by surviving Daleks who had lured the Doctor to the Cabinet War Rooms in 1941 in the Ironside Incident, which Amy experienced as her second trip in the TARDIS. (TV: Victory of the Daleks) These new Daleks joined the Alliance and were all but destroyed by the total event collapse, (TV: The Pandorica Opens/The Big Bang) but were restored as a result of the universal reboot. (TV: The Wedding of River Song, Asylum of the Daleks) In addition, spitfires modified with Dalek technology during the Ironside Incident were called upon by the Doctor to assist in the Battle of Demons Run. (TV: A Good Man Goes to War)

Soldiers of the Church were aware that the Doctor "once chased the Atraxi off a planet, then called them back for a scolding". (TV: A Good Man Goes to War) This had occurred in Leadworth on Earth when the newly regenerated Eleventh Doctor confronted the Atraxi pursuing Prisoner Zero, who had escaped imprisonment using the crack in Amy's house. (TV: The Eleventh Hour)

After Rory had been lost to the cracks, the Doctor was traveling with Amy alone when he met Craig Owens and his girlfriend Sophie, helping Craig save Sophie's life in an abandoned alien vessel. (TV: The Lodger) Following Big Bang Two, the Doctor recalled this incident when he confronted Silents within an identical vessel which was abandoned after the crew were killed by River Song. (TV: Day of the Moon) The Doctor later met Craig a second time following the birth of his and Sophie's son, Alfie Owens, with Craig recalling the incident that occurred in their last encounter. (TV: Closing Time)

Centuries later from his perspective, the Doctor found a crack on the planet Trenzalore, who he understood to be remaining "scar tissue", a structural weakness in the universe which served as an opening for the Time Lords to return to the universe after the Doctor in all their incarnations saved Gallifrey by relocating it to pocket universe at the end of the Last Great Time War. Ironically, as known by Tasha Lem, it was the Kovarian Chapter who destroyed the TARDIS, thus causing the Total Collapse Event and the resulting cracks, in an attempt to prevent the Doctor from reaching Trenzalore and allowing the Time Lords to return. Knowing that their enemies were waiting above Trenzalore, the Time Lords elected not to return to the universe at that time. (TV: The Time of the Doctor)

In the cracked universe, the 21st century Dalek invasion was among the events which fell to the cracks, coming to the concern of the Doctor that Amy did not remember it. (TV: Victory of the Daleks) Through the extrapolations of the Matrix, the Time War-era Time Lords became aware that Big Bang Two would cause subtle changes to Earth's timeline, citing the 2021 Dalek civil war as evidence that, at large, humans of the 21st century were unfamiliar with the Daleks.
