It is a widely acknowledged fact, that on the fields of Trenzalore, where no question can be answered falsely, that silence will fall should the ultimate question be answered. This is of course totally false. In the truthful answering of the ultimate question the one thing that will come from it is certainly not silence. What will actually occur will be the loudest, most ear splitting noise since the cacophony that is commonly known as the Last Great Time War.
So where did this misunderstanding occur? The truth is that information is like Chinese whispers. One person will state an original truth and those that hear will pass this on to others. But each individual's version of the truth will have inaccuracies so those that hear it will not hear the true story. As the word spreads further the information gets twisted and changed until, before you even realise it, the information bears no resemblance to the original truth.
In this case, the original statement 'silence will fall' was an objective, not a prophecy, the mantra of the organisation whose sole purpose was to ensure that the ultimate question was never to be answered. People who did not know the full story heard the mantra in a setting they didn't fully understand, a misinterpretation was spread through word of mouth, and soon it was believed that it was the silence that the organisation feared, when in reality they feared the noise.
The thing that nobody even realised was that the question would ever be answered at all. The one man in place to answer, ready to answer, would never answer. This man knows the prophecy himself, and he knows the truth of it. He knows that in answering the question Gallifrey will return, one thing that he yearns for with both of his hearts, but an event that can never happen. The shock to the universe of the loss of such a planet and the race that inhabited it was substantial, but it has adapted and changed to take account for this loss. The sudden return will create tidal waves and ruptures in the space time continuum. Great paradoxes that even the Reapers, self appointed guardians of the continuum, will be unable to clean. And let us not forget the plans of The Lord President of Gallifrey before he was banished to the void, or even the creatures of darkness that went with them. Should the question be answered it won't just be those lords of time who return to our world, they will bring with them a plague of Neverweres and Meanwhiles, Great Vampires, hordes of Travesty and many more.
But we should not feel that the actions to save Gallifrey were in vain. It may not be in our universe, but it is not dead and can continue to thrive in its own little universe; along with the Vampires and Neverweres and Travesties. The mistake is to believe that this is even the correct universe for it to inhabit, that Gallifrey's fall should never have happened. Everything happens for a reason. Who is to say that this is even the correct universe for Gallifrey to inhabit, there are many universes after all, how do we know which is the true one and which ones are false. Maybe the one where the cyber race has conquered half of the known worlds is the true original and the rest are merely bad copies. There is a universe outside ours where coordinates are negative, up is down, and people heal wounds in mere minutes. There is one parallel to ours, identical save for minor differences which allows a broken family to be reunited. There is even one, believe it or not, where Daleks, Sontarans, and the TARDIS are pure science fiction, the only notable life coming from a little blue orb orbiting a small insignificant star. Who is to say that Gallifrey's existence in any of these other than ours is wrong?
I do not make a habit of idle speculation; my business is cold hard facts. But in a world of contradictions and misheard truths one cannot be certain of the facts he beholds before his eyes. Not unless he travels directly to the source. Backwards along the established events, into the storm of fixed points, to times and places he should never have been.
A simple pebble dropped into a pond breaks the surface, kicking up the water and creating a noise that can be heard across the shore. And though the point of entry quickly restores itself, as though the pebble had never been there at all, the ripples continue to spread until the entire pond feels the pebble's influence.
I am that pebble. I create ripples wherever I walk. If I did not, I would not be the Informant. If one seeks knowledge, he must be willing to create a few waves.
I have told you all this for free, but if I am to give you any more I must insist on a price. Information is my business, and it is a very valuable commodity. Make me an offer and I will tell you this story. The story of what truly happened on the fields of Trenzalore. Not just in this universe, but the one across the pond.
