Okay. So this story is obviously very AU. I've disregarded a lot of HP Canon and some parts of Twilight Canon. The HP timeline and events for the earlier books will be pretty much the same, with some changes to Harry's childhood, and his treatment by the Dursleys. But I've altered a lot beginning with Book 4 onwards. The only main part of Twilight canon I've changed up to where this story begins is that Bella manages to settle things between the vamps and shifters so that they're somewhat friends with one another. The following story is meant to take place after the end of the "Final Battle" and somewhere around the end of New Moon to the beginning of Breaking Dawn. I may bash some characters, and make other characters OOC but this is a fanfic so deal with it. The main paring will be slash, but while I am considering at least one FemSlash paring, the others should all be Het.

The introduction is short and split into two parts. The first part is the intro for the HP characters and the second part is for the Twilight ones. This is just to give you a basic overview of what characters are going to be involved in the story, and where they're coming from. There is only dialogue at the end.

Disclaimer: I do not own Harry Potter, Twilight, or any of the characters within those series'; I'm just using them to suit my purposes.

Introduction- End of One Life, Beginning of Another

The war had been hell. There was no other way of describing it. War is always hell. They had watched their friends fight and die; they had lost so many people, and had been betrayed by many others. No one knew who to trust, no one knew where to turn, and no one knew where to go. Everyone was terrified.

They had banded together. The seven of them. They didn't trust anyone else and didn't really have anyone else to turn to. So they turned to each other, trusted only each other. The Ministry and the Order put the weight of the war on Harry's shoulders. On the shoulders of a teenage boy who should be dating and laughing and enjoying his life. Not training, not killing people.

They created a team called Sin. There were seven of them, each with a code name of one of the seven deadly sins. Only they knew about the team, only they called each other those names. It was the only way they could be sure who walked into their base was the same person who came back.

Harry was Wrath. They had decided upon it after seeing him truly angry for the first time. They had seen him yell before. They had seen him irritated. But they had never seen him truly furious until then. Death eaters had ambushed Tonks and Remus. They had had Teddy with them. The three were killed. Harry had gotten there first. They had watched as his magic lashed out and ripped apart thirty death eaters while he held his godson's dead body close. There was nothing left of them when he finally calmed. Just a street drowning in blood. He was their leader.

Hermione was Greed. She was not truly a greedy person except when it came to knowledge. She desired to know everything, and would sometimes go to extreme lengths to get that knowledge. They had watched as she tortured Bellatrix for days until she finally told her where her parents were. They got to them too late. She was their interrogator.

Ron was Gluttony. The code name had been picked for him more as a joke than anything else. With the ways that he ate it was really no surprise he would be stuck with the name. He was part of the reason the seven of them were still alive. He always seemed to know exactly how o keep them from getting killed. Where to go to stay safe. When to move on before they were caught. What to do for them to survive every battle. He was their strategist.

Draco was Pride. Even as he turned his wand on his father and crucio-ed him into insanity he was still the very epitome of a Pure-blood heir. Perfect appearance. Perfect posture. Perfect manners. He looked like an avenging angel on the battle field instead of a soldier. His main purpose was off the battlefield though. Having grown up in the middle of magical society with an in-depth knowledge of politics and a silver-tongue. He was their public face.

Neville was Sloth. He was far from lazy but the name suited his calm, laidback demeanor. He had grown from a sniveling boy into a large brute of a man capable of hiding in the shadows un-noticed. Slipping around the edge of the battles and stilting death-eater throats with a muggle knife. They never knew what hit them. He was their stealth.

Luna was Envy. As a girl she had been teased and made fun of. But as a woman she was beautiful, gaining the envy of many who laid eyes on her. She was gentle with a healing hand among the seven of them, yet merciless and vengeful in the face of an enemy. She wore the same gentle smile both while healing their wounds and while she cast cutting curses and fiendfires at the enemy: never missing. She was their healer.

Blaise was Lust. A Chocolate colored charmer, he could sweet-talk himself into anyone's trust. He had the same mischief in his eyes as the twins and a smile that could make anyone swoon. He had no problems using that charm to lure the wives and daughters of death eaters into his bed only to obliviate them once he had their secrets. He was their spy.

The seven of them were unstoppable. The ministry had given them a carte blanche to do whatever was necessary to win the war. The order could not control them, no matter how hard they might have tried. The death eaters could not find them or destroy them. Voldemort could not take them down. They did whatever they had to, even things that might have lowered them to the Dark Lord's level. In the end, it was all worth it.

The final battle had been the worst of them all. Voldemort's army had been greatly diminished. They had decided on a last stand at Hogwart's. Sin had tried to save the students, but the death eaters had gotten there too soon. So many children, first years, second years, students of all ages. Their corpses littered the battle ground that had once been Hogwarts. The castle herself had barely survived. The Order was almost non-existent. But they had won. They had ended it. They had finally killed that snake-faced monster.

While the ministry and the wizarding world had celebrated, they had not. They had lost too much to celebrate. Each of them with ages from 16 to 19 had aged too much. They felt decades older. But it was over. They could finally rest. So while the rest of the wizarding world partied, Sin slept. Hidden away in the Room of Requirement.

The press was unbearable. Constantly showering them with praise, following them, crowding them at every chance. They couldn't take it. They left. Left the wizarding world. Left Brittan. Left Europe. They went to the Muggle world. To America. To Washington. To a little town barely even on the map. They went to Forks.

Her life had been simple enough. Before she came back to Forks to live with her dad. After that it was as if the world had been turned completely upside down. Vampires and werewolves existed. Her boyfriend probably wanted to suck her blood. Her best friend could turn into a giant beast and definitely wanted to date her.

She had lived her whole life in a bubble. She knew that. She had known that she hadn't seen much of the world. Let alone the evil in the world. But it was more than that. She had never thought that those fairytales and stories had any truth to them. Now she knew better. At least, she knew a little better. She knew there were things out there she hadn't believed in before. She knew there were things she didn't understand. And she had finally gotten her first real taste of the evil of the world. The evil in people's hearts.

James had been tough. She had been terrified of him. Until then she hadn't feared vampires. She hadn't thought she needed to fear vampires. After that she knew better. She understood why Edward had kept asking why she wasn't afraid of him; why he kept telling her she should be. Not that that was enough to keep her away.

Then he had left. That had broken her. Completely. She had him back now, but still. Now her greatest fear was not vampires like James. It was not the Volturi. It was not even the shifters. It was him leaving again. Yet, she feared Jake leaving just as much. Edward was the love of her life. Jake was her rock. Ed kept her at peace, and Jake kept her grounded. She needed them both in a way.

She needed the others too though. The La Push pack and the Cullen Coven were both family to her. It was why she had worked so hard to make them get along. To make them like each other. Because she couldn't bear to chose between them. She had done it too.

It had taken weeks of screaming and crying and ranting at both sides to get them to agree to spend some time around one another. In the end they had met up at the Cullen household and Esme and Emily had cooked for everyone. It had been a surprise, both to the vampires and to the shifters that they actually enjoyed each other's company.

Jacob and Seth got along great with Emmet. Leah and Rosalie shared an odd sort of companionship. Sam often spoke to Carlisle. Esme and Emily were two peas in a pod and mothered everyone. Paul and Jasper would quietly enjoy each other's company. Embry and Quill and Alice got along with everyone. Edward would never really be friend with the shifters, but he got along with them. Though his relationship with Jake was rather strained.

Spending time together became a weekly event. Alice gift started working around the shifters. Though when they played a part in her visions they were blurry. Thus she would know if she had a vision with a shifter in it but wouldn't always know which shifter. They came to trust her gift. Always listening intently to any advice she gave them.

So when Alice suddenly went rigid, her eyes far away in the middle of a conversation with Jake everyone went silent. The vamps and shifters and Bella all gathered around her to wait for her to come out of it. She blinked.

"A new family is coming to Forks."

Bella blinked. A new family? What did that have to do with them? Alice smiled around at the shifters and giggled in that I-know-something-you-don't sort of way.

"Some of you are going to find your imprints!"

So that's the intro. The main pairing will be Paul/Harry because I think the idea of putting too hot-heads together will be entertaining. Blaise will be with Leah, and Jacob will end up with either Luna or Hermione. I know usually Ron and Hermione would be together but I don't want that for this.

Let me know who you think the others would be good with. Keep in mind the students at Forks because I do want to include them in the pairings.
