The Alliance ( The Pandorica Opens ) The Alliance was an association of diverse races , mainly 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 his TARDIS would cause the cracks in time , which in turn would end all of existence . In truth the blame belonged to Madame Kovarian and her faction of the Silence in one of their many blunders in an attempted murder of the Doctor . The Alliance devised a plan to trap the Doctor in a specially - built prison known as the Pandorica to prevent him from piloting his TARDIS . However , none of them knew River Song could pilot the TARDIS as well , which led to the explosion . They were temporarily removed from existence , but thanks to their creation , the Pandorica , the Doctor reversed the damage done by the Silence and restored them to their proper times without memory of their alliance . History . Members of the Alliance visited Amy Pond ' s house the night she left with the Eleventh Doctor in 2010 . They traced the psychic imprints there , sampled Amy ' s memories and used them to create a scenario the Doctor could not resist to lure him to the Pandorica . This resulted in the Nestene Consciousness creating Auton s disguised as a small legion of Roman soldiers from a picture book that Amy owned . They were set near Stonehenge , also featured in the picture book , in the year 102 AD . Among the Auton duplicates was a copy of Rory Williams , presumably created because a photograph of Rory in a Roman centurion costume was kept in the pages of the book . The Pandorica , named for " Pandora ' s Box " , another book Amy owned , was placed under Stonehenge . A Cyberman was placed with the Pandorica to act as a sentry , but was heavily damaged before ultimately being destroyed by the Auton duplicate of Rory . Stonehenge acted as a transmitter , summoning members of the Alliance to converge on the Pandorica when the Doctor arrived . The Doctor managed to keep them at bay for an hour by extending the Pandorica ' s force - field technology around Stonehenge ; he also warned them to " do the smart thing " by letting someone else try first due to how many times he ' s defeated them in the past . Once the Pandorica was ready to open and hold the Doctor indefinitely , a high - pitch signal went out to the Auton copies and activated their programming ; however , Rory ' s copy possessed the heart and soul of the original , allowing him to fight back . They confronted the Doctor and explained their intentions . They had concluded that the cracks would be caused by the destruction of his TARDIS ; therefore they sealed the Doctor inside the Pandorica to prevent him from using it , believing only he could pilot the TARDIS and this would avert the disaster . As they sealed him inside , the Doctor tried to save them and the entire universe , warning them desperately of the true threat . However , unknown to them , River Song , the Doctor ' s wife and companion , could also pilot the TARDIS . She was attempting to do so at that time , which caused the destruction of the universe . The Alliance ' s plan failed and all the Alliance species , including the Dalek s , Cybermen , Judoon , Sontaran s , indeed , everything in the entire Universe save the Earth and Moon , were wiped from existence , leaving only stone ' after - images ' behind . The stars , including the Sun , no longer existed , because they all went supernova at the same moment . According to the Cybermen , all alternate universes and the Void were also wiped from existence . Ironically , the Alliance ' s attempt to save the universe destroyed it . ( TV : " The Pandorica Opens " ) The Doctor piloted the Pandorica into the TARDIS explosion , creating a second Big Bang that " reset " the universe . This removed the cracks from existence . As the Pandorica was used to save the universe , the Alliance helped the Doctor in the effort , so their plan did succeed . However , as the cracks never existed , the Alliance was never had a reason to form in the re - created version of the universe and the members of the Alliance were restored to their original forms and places in space and time .
