"You can never plan the future by the past." - Edward Burke
It is 1975 and the Marauders are about to start their final year of schooling at Hogwarts School of Witchcraft and Wizardry. The times are dark – old friends are mysteriously vanishing and old enemies more openly showing their contempt for everything the Ministry of Magic had always stood for.
"Every action has an equal and opposite reaction."
Every action they take from here on will be towards their future, setting in motion the paths to their destinies and the lives outside Hogwarts that are waiting for them. Not everyone is ready, not everyone is sure that the path they have always claimed to want is the right one for them, and the time is quickly coming where that will have to be told, and new plans made.
"Everything happens to everybody sooner or later if there is time enough." - George Bernard Shaw
It is 1998 and Harry Potter has finally managed to defeat Voldemort. His life has never been so peaceful. Despite this, not all the Death Eaters have been caught, and the war is not over. In an attempt to make dark times slightly less frightening, George Weasley has invented a journal. As long as it is written in regularly, it will alert the owner or those around them if something seems off – if the entries change, or the person writing in them acts differently the diaries will send an alert to all other diaries the user has chosen to link to it. It is the surest defence they have against Imperius and possession, and the product almost instantly sells out.
This is where we start.
"The trouble with our times is that the future is not what it used to be." - Paul Valery
Things will start to change. Memories that people don't remember having will be written in great detail. Friendships with people that were hated will be described with love. People that were dead are now alive, and, most terrifyingly, the other way around. The answer is a mystery. All that is known is that sometime in the near future, for a reason that no one knows, things will change. All normal journals, all newspapers and records will reflect the fact that this is the way it has always been. But the enchanted journals, the specially linked papers created by Weasleys Wizarding Wheezes will insist that things are not what they seem to be.
Who can you trust, when the entries of your friends were mourning your death, and you're now engaged to the person your diary insisted that, before your death, you despised with a passion? Who can you hold on to, knowing that in mere days, everyone you love could become your bitter enemy?
