Starting Over

Looking back on it, Harry should have known this would happen. But he just didn't think it was possible at all this time around - he'd just saved their lives, hadn't he?

He supposed it was a good thing he was orphaned in the war. Draco shuddered to imagine what his father thought of the situation.

The ban Gran placed on Neville was pushing it. It wasn't just a ban - it was fortified with magic.

It was such a shame, really, that things worked out the way it did. Luna, of course, knew all of it would happen.

After the final battle, things go back to normal. Harry, Ron and Hermione all go to school for one last year and one last adventure, one without Voldemort. Harry and Ginny are living their lives happily and have great plans for a great future.

At least, that's how it was supposed to happen.

Instead, everyone begins to fear Harry. If he could defeat Him, then who's to say he won't follow the same path? Who's to say he won't go dark?

Harry is falling into a depression that he can't seem to escape. The ones he depends on most have abandoned him and the one who hasn't can't speak to him. He feels like he's drowning and there are leads attached to him, helping him along.
Neville does his best, honest, but there isn't much he can do, thanks to Gran. He wants to help, but he physically can't, and it's slowly killing him. Maybe... no, that wouldn't work.
Luna does her best as well. The creatures she sees are messing with his head, and no matter hard she tries, she can't help him get rid of them. Maybe someday, somehow.
Draco doesn't do much - it's not his place. He's been nothing but hurtful to Harry, but he regrets that, really. It will take time to get Harry to trust him. He wants to help but he knows it'll be rebuffed. Right?

A meeting where they all get to know each other gets interrupted. The ball of light shouldn't be trusted, but Luna say's it's safe. So when Luna wakes up ten years old again, she has four months to prepare for her friends' arrivals.
