Peter Pettigrew was all alone.

Once he had his friends, his friends who would die for him, his friends who had trusted him.

Now they were gone.

Two dead, one Arrested for His murder and one who would've had his whole world turned upside down by the horrible news. Poor Remus would be devistated. Peter knew, he had lots of experience.

According to the ministry, Sirius Black was to be sentenced to life in Askaban for the murder of fellow wizard Peter Pettigrew, along with 13 muggles. He was also known guilty of giving the Potters location over to Voldermort... He had stopped reading there, unable to carry on. Instead he curled up in his cadge and tried to sleep, but with guilt pressing you deep into the ground, sleep does not come easily...

Remus Lupin was a mess. He was in disbelief. There had been a spy, everyone knew that. But the Secret Keeper was supposed to be the most trustworthy! Sirius. Sirius was chosen because he loved his friends above all else. The fact that he had given James, Lily and Harry to Voldemort, Remus just couldn't process it. Only two days ago they had been having dinner together, with some other friends of course.

It had been nice, they'd cracked jokes, they'd caught up. All of them had been nervous, it was obvious. No-one except the spy knew who he/she was. Admittedly, Pete had seemed even more nervous than usual, Remus had dismissed it because Peter was always nervous. He had every right to be, after what happend during their time at school... But what if Peter had guessed or learnt that Sirius was they spy?

The two had exchanged allot of looks that evening and when they got home Sirius still wouldn't tell Remus what it was about, they'd just gone to bed. Why didn't Pete' tell Remus that night? They could've gone after Sirius together! Oh, but Peter wouldn't know that! He would just think that Remus would be mad at him for suggesting that Sirius was the Spy

So many questions, so few answers. With the full moon coming up, Remus couldn't cope with all the stress. He curled up on the sofa, breathing in the last traces of Sirius from the blanket, and closed his eyes. He felt more alone than he had ever been in his whole life.

Sirius Black was angry. He couldn't believe it. Peter was the person he thought least likely to give information. He had convinced James to switch Secret Keeper to Peter because he was the least obvious option to the Death Eaters. But then this happens!

First, Peter gives the location of their friends house to Voldemort, condemning them to death. Then, he has the nerve to pretend to be happy to see Sirius. Next, he acts like he is shocked and hurt that Sirius believes that he is the spy. Lastly, he blocks Sirius' spell so that it rebounds around the whole street, escaping as a rat to frame Sirius for not only his murder, but Lily, James and thirteen muggles as well.

But Sirius is innocent and as he sits in his cell, as Remus dwells on the loss of his closest friends, as Peter drowns in guilt, self-loathing, hurt and the never ending 'what if's'. The boy who lived is starting his first journey. His journey to becoming the Chosen one, the saviour of the Wizarding world. But before his story, his life even begins, there is another one. One that shapes and over-lapps his. This is the story you will hear: The story behind the Mighty Marauders.
