The Pandorica Alliance

The Alliance was a large group of aliens, including many of the Doctor's enemies, formed to stop the greatest threat in the universe, which they all believed to be the Doctor. They predicted that the explosion of the TARDIS would cause the cracks in time which in turn would end all of existence. They devised a plan to trap the Doctor in a specially built prison known as the Pandorica.

Members of the alliance travelled to Amy Pond's house, the night she left with the Doctor, and by tracing the psychic imprints there they were able to sample Amy's memories and use them to create a scenario the Doctor would not be able to resist, as a way to lure him to the Pandorica. This resulted in the creation of a small battalion of Autons, disguised as Roman soldiers from a picture book that Amy owned during her childhood, which were placed around Stonehenge, also featured in the picture book, in the year 102AD. Among the Auton duplicates was a copy of Rory Williams, presumably created because a photograph of Rory in a Roman centurion costume was kept within the pages of the book. The Pandorica, named for "Pandora's Box", another book Amy enjoyed as a child, was placed under Stonehenge. Stonehenge acted as a transmitter, allowing the alliance members to converge on the Pandorica when the Doctor arrived. Some representatives of the alliance confronted the Doctor and explained their intentions. As they had concluded that the cracks would be caused by the destruction of his TARDIS, they sealed the Doctor inside the Pandorica to prevent him from using it, believing that only the Doctor could pilot the TARDIS, and therefore averting the disaster. However, unknown to them, River Song, one of the Doctor's companions, could also pilot the TARDIS, and was attempting to do so at that time, an action which caused the apparent destruction of the universe.

The Alliance's plan failed however, and as a result, several species, including the Daleks, Cybermen, Judoon, Sontarans and all other members of The Alliance were wiped from existence, leaving only stone "after-images" behind. On the other hand, one Dalek was later revitalized by the restoring energies of the Pandorica, and attacked the released Doctor and his allies. River Song destroyed it by shooting it in its eyestalk.

The Doctor threw the Pandorica into the TARDIS explosion, creating a second Big Bang that "reset" the universe, removing the cracks themselves from existence. Comically due to the Pandorica been used to save the universe, The Alliance technically helped the Doctor save the universe and thus their plan did succeed. As the cracks never existed, the Alliance itself was never formed. All members of The Alliance were restored to their original form and place in space and time. (DW: The Big Bang)
