Chapter 1: Activation

It had not been a good year for Harry Potter.

He had spent the majority of it as the pariah of the school, and the entire wizarding world for that matter. He had endured detentions that had bordered on torture, had not been allowed to play Quidditch for the majority of the year, had again come face-to-face with Voldemort and later learnt of the prophecy that apparently determined his fate, and worst of all, he had gone through the pain of losing his Godfather, Sirius Black.

It was this that lead to Harry's feelings of depression and despair. He was still raw from the loss of Sirius and spent most of his days lost in his tangled and guilt-ridden thoughts.

It was only as he was packing his trunk before the end of year feast that Harry felt the first positive emotion since arriving back from the Ministry.

Hope.

Harry could feel his heart rate quickening as he looked down at the letter attached to the crumpled brown package he had just found at the bottom of his trunk.

This is a two-way mirror, I've got the other one of the pair. If you need to speak to me, just say my name into it; you'll appear in my mirror and I'll be able to talk in yours. James and I used to use them when we were in separate detentions.

The words of his Godfather lay before him. Harry's eyes stung with unshed tears. In his desperation to hear Sirius' voice again, Harry tore off the paper and found himself looking into his own green eyes as reflected by a neatly framed mirror.

He held it up to his mouth and whispered into it, 'Sirius.'

Nothing happened.

'Sirius! Sirius Black!'

His reflection stubbornly stared back at him.

Harry collapsed to the ground, the mirror clutched to his chest. This was it. This was his last hope of ever seeing his Godfather again. He could feel his chest constricting tightly in grief as he instinctively curled into himself, bringing his knees to his chest.

Suddenly, the wizard was momentarily distracted by a glowing green light emanating from the mirror in his hands. Harry yelped and promptly dropped the glowing object to the floor only to watch as it slowly morphed into a very different shape. The mirror first expanded, then lengthened out, making it thinner and more narrow then before. The glowing dimmed and Harry could see the new form of the object.

It was a dagger. It was elegant in its design, and was different to any other dagger Harry had ever seen. It was a shining silver with a flawlessly sharp blade and no hilt. Instead, there was a rounded handle on the end that looked to be made of a dull, rutted metal that lacked the reflective quality of the blade itself. It seemed to be shaped so that it could effortlessly glide through a person's body without even slowing down. It was beautiful in a very dangerous way.

Harry picked the dagger up and held it closely to his eyes to inspect it further. It was then that he saw an intricate green cross embedded on the handle. Something about the cross unsettled Harry; it felt foreign to him somehow, but at the same time, he felt himself drawn to it.

Harry was confused. He had been around magic long enough to not be all that surprised by the random transfiguration of an object, however, he couldn't figure out how it had happened. He hadn't changed it himself, and there didn't seem to have been an enchantment on it before, as the letter told him the mirror was once used back when his father was at Hogwarts. Why then, did this happen? And what was with all the green glowing light? For a moment, it had reminded Harry vaguely of the killing curse, but he couldn't figure out a relation between the two things.

Remembering that he was running very late for the feast, Harry hurriedly put the newly-formed dagger back into his trunk and raced downstairs for the official end of term. Throughout the final speeches and announcement of the House cup, Harry's mind continued to dwell on the strange object that currently lay in his trunk.

Meanwhile, in a towering black castle situated precariously on top a cliff just outside London, an exhausted-looking man in a white coat burst into a room littered with papers and empty coffee mugs.

'Komui, Sir, we've found another one – another piece of Innocence has been activated.'

The man named Komui leaned to look around the piled pieces of paper on his desk, his eyes widened, 'Well, I guess we'll have to pay it a little visit, now won't we?'

Just a small chapter introducing my basic idea. For ages I've been intrigued with the idea of doing a crossover between HP and DGM, but I couldn't quite figure out how I was going to do it. I loved the idea of Harry becoming an exorcist, but at the same time I loved the idea of the exorcists going to Hogwarts.

So I figured, what the hell, I'll just do both. So in this story, I'm planning to incorporate both of these things together! (Ambitious, I know) Though the Hogwarts part won't come until a little bit later – Harry has to get boss first, obviously.

So, tell me what you guys think of the idea, please review so I know I'm not totally killing you all with my rampant plot bunnies, and look forward to the next update

Tara out.
