The marauders were not who you think they were in fact all that you know is a lie. The true story lies with a young woman who was hurled into time and stripped of magic to save the people she loved. In turn everyone lost there memories and gained new ones.

Fake ones

Because in reality

Severus didn't know lily evens.

James potter was not friends with Remus Lupin or Sirius black.

The only time they set eyes on each other was in the great hall and felt the sadness of the potter death shroud the order.

And in the end the young women did exist

To remember is a blessing

Now that things are, once again, remembered Harry wants to know how all this; those lies they all lived began and what truly happened in the past. Because no one thought to tell him

And in the end it all as to do with the boy who lived  In the end the past always comes to light and reflects the future
