Chapter 1: Betrayal by Pettigrew

Disclaimer: I don't own Harry Potter or Percy Jackson. They belong to Rick Riordan and J. K. Rowling. I was simply borrowing them without permission.

Sirius Black was not having a good day. Why, you may ask?He found out one of his best friends was one of those bloody death eaters!

What's next, Snivellus being a Gryffindor? He supposed he was always a little wary of Pettigrew. After all, rats are known for their disloyalty.

He had simply "borrowed" Prongs' invisibility cloak to give the Slytherins a little "present". It would've made them smell better anyways.

He suddenly heard voices. He was in an empty corridor leding to forgotton rooms. 'There shouldnt be anybody here.' he thought to himself.'I guess it wouldn't hurt to eavesdrop. After all, if it was meant to be private, they should talk quieter'.

A very nervous voice whispered " I Peter Pettigrew pledge myself to Dark Lord. I shall become a death eater in honor to thee and pledge thy self to the cause. I will get Black out of the picture." Sirius muffled his gasp.

Anger coursed through his body. It took all his will power not to hex the git into oblivion. He should warn James and Remus first. He hoped the little weasel die a very nasty death.

Sirius rushed hurriedly to the Gryffindor tower. All while thinking VERY inappropriate thoughts. Suddenly, he bumped into Filch! 'Bloody sodding hell!' Hadn't he gone through enough today? He needed to warn his friends before it was too late!

"Well, well, well. What do we have here? A little Gryffindor out of bed after curfew? You're coming with me to McGonagall's office!"

James Potter was sleeping. Very blissfully I might I add. After winning a quidditch game, Griffindor vs. Slytherin and a raging house party, who wouldn't?

That was why he was so confused when Peter, one of his most trusted friends, woke him up. Peter looked like he had lost a fight to a sumo wrestler! He had a bloody eye, a broken looking arm, and not to mention the scratches and bruises all over his body. In other words, he wasn't looking very king of the world right now.

"Who did this? I'll kill them!" He looked over and saw another terrible sight. Remus ... was angry! And you do not want to see a werewolf when he is angry.

"Who did this Peter?!" Peter was hesitant. It was Black." He spat that name out venomously.

"Sirius?!"

"Padfoot?!"two voices called out.

"Him?!" they said together.

"It was him! I was just walking to the kitchen because I was feeling hungry you know? Then next thing I knew, him and a bunch of Slytherins were hexing me. It was so painful and I couldn't understand why he would do that to me. I could barely transform to escape. He became a Death Eater, I know it!"

James couldn't see anything but a blinding light of fury. He could not believe his best friend betrayed them like that. After all, once a Black always a Black. When Black gets here, there will be some serious consequences.

Remus could not believe his ears. Oh he heard Peter all right, loud and clear. It's just the aftershocks that's killing him.

How could Sirius, a brave and friend betray them. After all they've been through too!

I mean, had any other 15 year old make a map of Hogwarts? Or become Animangi at the young age. Even more impressive, it only took them two years.

' I guess war does that to people, it changes them. Turns them into a every man for himself kind of thing.'Remus thought that Sirius was always a happy go lucky kind of person, always cheerful and optimistic.

Apparently, the saying never trust a book by its cover is true.
