Prophecy A prophecy was a prediction of future events , usually offered by beings with precognitive abilities . Many prophecies were made by those with psychic abilities . War predictions . Though they had power over all of time and space , due to the Protocols of Linearity , Time Lord s were incapable of directly observing their own future . However , throughout their history , multiple parties predicted the destruction of Gallifrey , usually in a time war . These were collectively known as War predictions . ( PROSE : " The Gallifrey Chronicles " , " The Book of the War " ) The Sibyl . The Sibyl foretold that the Doctor ' s TARDIS , the " blue box " , would appear at the time of " storms and fire and betrayal " . This came true in 79 Pompeii when the Tenth Doctor arrived and caused Vesuvius to erupt , saving the Earth at the cost of 20 , 000 lives . ( TV : " The Fires of Pompeii " ) The Gift of Pompeii . While in Pompeii , the Tenth Doctor and Donna Noble encountered Evelina and Lucius Petrus Dextrus , both of whom possessed telepathic abilities and the ability to see into the future as a result of the Pyrovile s and a time rift cracked open by Vesuvius ' eruption . Because of this , they made some startling prophecies about the Doctor and Donna ' s futures . When asked by her parents if she could see anything , Evelina predicted that someone would have to make a terrible choice . This was about the Doctor having to choose whether to destroy Pompeii by causing Vesuvius to erupt to save the world . A prediction of Lucius ' was to the Doctor : " She is returning . " ( TV : " The Fires of Pompeii " ) This referred to Rose Tyler ' s return . ( TV : " Turn Left " , " The Stolen Earth " ) He predicted that Donna had " something on [ her ] back " . ( TV : " The Fires of Pompeii " ) This referred to a Time Beetle which attached itself to her back , changing the timeline . ( TV : " Turn Left " ) The " false prophet " Donna Noble . The time travel ler Donna Noble , who was later referred to as a " false prophet " by the Sibylline Sisterhood , prophesied to Evelina that Vesuvius was going to " explode " on 24 August 79 and Pompeii would get buried under rocks and ash . She knew this not because of any psychic abilities , but due to her historical knowledge . The Sisterhood were unable to foresee this , as the time rift that had awoken their powers of sight " echoed into the Pyrovillian alternative " , but the " prophecy " nonetheless came true . ( TV : " The Fires of Pompeii " ) Dalek Caan . When he travelled into the Time War , Dalek Caan saw all of time and space , past , present and future . The experience drove him insane , but it also caused him to work to orchestrate the Daleks ' downfall . Dalek Caan predicted that the Doctor was coming and referred to him as the " three - fold man " . ( TV : " The Stolen Earth " ) This referred to the three Doctors who converged to stop the Daleks , the tenth incarnation , the meta - crisis Doctor and the DoctorDonna . Dalek Caan predicted that the Doctor ' s Children of Time would gather and the most faithful one would die . He predicted this repeatedly . His last words were , " One will still die " , as his final prophecy . In actuality , this referred to an aspect of Donna Noble , the " Doctor Donna " , which the Doctor had to wipe from her mind to save her life . Dalek Caan also predicted that the Doctor ' s true soul would be revealed . Davros claimed that when the Doctor ' s companions threatened mass destruction to stop the Daleks , the truth about the Doctor was revealed ; he refused to use a weapon , but moulded his companions into them . Dalek Caan predicted the end of the Dalek race and foresaw that the Doctor would be the one to cause it . Dalek Caan urged the meta - crisis Doctor to fulfil the prophecy of the Daleks ' destruction and made him realise it needed to be done . At Dalek Caan ' s insistence , the meta - crisis Doctor destroyed the Daleks . ( TV : " Journey ' s End " ) Carmen . As she said goodbye to the Tenth Doctor , Carmen made a prophecy about his future , telling him , " Your song is ending sir . . . It is returning . It is returning through the dark and then Doctor , oh , but then . . . He will knock four times . " ( TV : " Planet of the Dead " ) The Tenth Doctor did everything he could to stop this prophecy from happening , even electrocuting Andy Stone to prevent him from knocking four times , ( TV : " The Waters of Mars " ) but it proved inevitable . When brought back the Time Lord s , the Doctor realised what " it " was . As a result of breaking the time lock on the Time War , the Master had brought back more than the Time Lords ; he had brought back Gallifrey , the " it " from Carmen ' s prophecy that was returning . Gallifrey returned close to Earth and nearly destroyed the planet . After the Doctor and the Master defeated the Time Lords and banished Gallifrey and them back into the Time War , the Doctor believed that he was safe and had averted the rest of the prophecy , when four knocks sounded . " He " had referred to the Doctor ' s companion , Wilfred Mott , who knocked four times repeatedly to get the Doctor ' s attention to be set free from a radiation booth he was trapped in after freeing a man . To save him , the Doctor sacrificed himself and absorbed a fatal dose of radiation lest Wilfred absorb it and die . This caused him to regenerate .

( TV : " Planet of the Ood " ) When the Doctor later returned to the Ood - Sphere , the Elder Ood chanted a prophecy , " It is returning . They are returning . He is returning . Both he , it and they are returning , but too late . " " He " turned out to be the Master , who was brought back to life . The Master transplanted himself into every human on Earth . When all the new Masters concentrated on the drumming inside his head , he pinpointed its origin . This meant that the High Council of Time Lords , who retroactively implanted the signal in his head when he looked into the Untempered Schism , were able to send a Whitepoint Star to Earth , making contact physical . This was the " they " . Along with them , Gallifrey also came through , the " it " . ( TV : " The End of Time " ) The Trickster .

( TV : " The End of Time " ) " Silence will fall " . The religious order known as the Silence believed that " Silence will fall when the Question is asked " , better translated as " Silence " must " fall " . According to Dorium Maldovar , " on the fields of Trenzalore , at the Fall of the Eleventh , when no creature can speak falsely or fail to answer , a question will be asked . A question that must never ever be answered : Doctor who ? " The Silence wished to prevent the Doctor — the one man , they believed who knew the answer — from responding . They thus sought to kill him several times during his eleventh incarnation . ( TV : " The Wedding of River Song " ) Eventually it was revealed that Trenzalore was the location that the Time Lord s were attempting to return to the universe through a crack in time , broadcasting the question " Doctor who " through it . If the Doctor said his name , they would use the crack to return to the universe . The town the crack opened on , Christmas , had a Truth Field surrounding it , preventing anyone from lying . The Eleventh Doctor refused to say his name as it would cause all of the universe ' s most dangerous species to descend on Trenzalore and cause a new Time War , thus destroying the universe . The Church of the Silence became determined to stop this , to help the Doctor and keep silent and protect the planet from his enemies , declaring that " silence will fall . " The Kovarian Chapter broke off and tried to use time travel to prevent the Doctor from ever reaching Trenzalore , causing the events that brought him there in the first place . The Doctor spent centuries defending the planet until all but the Dalek s left or were destroyed . At the point of death , the Time Lords intervened by granting the Doctor a new cycle of regeneration and then closing the crack . The Doctor destroyed the Dalek ships with his regeneration energy and then regenerated into the Twelfth Doctor . ( TV : " The Time of the Doctor " ) Apollonians .
