Prologue

The ground beneath his feet made a squishing noise the moment he stepped onto the slightly damp soil of the cemetery fields. Though the place was silent and unpopulated, one specific area caught his attention and Albus Dumbledore couldn't help but feel a little sad.

Blood was staining the ground in front of a gravestone creating a huge mess. It clung to the random objects surrounding the grave and trailed on to a nearby tree where a small child sat, looking lifeless and broken. In front of him knelt a red-headed man dressed in a black coat and with a round golden object perched above his hat.

Despite the situation, Dumbledore's eyes twinkled in recognition and he moved to intercept the sad fate the child was destined to endure.

It was bitter to think that these children had to carry such heavy burdens at their age. So young…and yet already entitled to such a difficult life. It really was cruel how fate worked, and it was only made more evident the moment he was standing exactly behind the crouching figure.

Silver hair. Silver like his own. There was a scar running down the child's blood caked face starting with an inverted pentacle above his left forehead. It ran down his glowing eye and moved to an intricate design, stopping a few inches above his left jaw. The child was crying too. Salty tears with one eye and blood with the other.

How unfortunate… Dumbledore thought.

It was a curse. A scar that reminded him of the one the boy, Harry Potter, had acquired after Voldermort's assault on him all those years ago. How painful it was to watch, even for him.

He was already certain he would have to endure seeing the young wizard of their school face death again and again. To see another who could have a similar fate was simply heart wrenching. His mouth curled, but he wasn't able to do anything more.

The sigh that escaped the other mans lips alerted Dumbledore that the man had moved. He turned and watched the figure stand up, though not turning to face him.

"Albus" The man acknowledged and dug a hand to the insides of his pockets. "What bring you here of all places?" The man said. The wizard simply disregarded the others rude behavior and greeted him.

"Good evening to you too, Marian", he said before he stepped forward and took his old friends place crouching by the child.

It was only then that he noticed the greenish glow emanating from the cross embedded at the back of the child's red hand. Dumbledore's eyes softened in sympathy and he reached out and traced his fingers around the rough edges of the glowing crystal knowing perfectly well what it was.

"Your war is cruel, my friend. Taking away this boys childhood before it even began." He said. The red-haired male only huffed, lighting up what he now knew as a cigarettes before finally turning to face him.

"You're one to talk when your chosen one's only a year or two older." Marian's gaze moved back to the boy and he stuck the stick to his mouth before he continued. "Besides, our wars have different circumstances. This one will have to learn all the necessary things to survive in life and the war." He paused again and let out a smoky breath. "Unlike you wizards, we are rather short of warriors."

Dumbledore merely chuckled in response. Standing back up, he straightened his robes and adjusted his glasses. He did not say anything, but he knew it was true. Their wars were different, and though the loyalties on their side of the war was unsure, they who called themselves exorcists were simply too outnumbered.

Still…

"You're going to start training him so soon?" Dumbledore inquired. Marian raised a brow.

"What are you planning?" The exorcist asked back and Dumbledore then smiled.

General Cross Marian, a high ranking exorcist. A warrior fighting a different war, a friend with a similar cause.

Dumbledore always knew the man was smart, and he was happy too that he had the chance to meet him and eventually call him a friend.

Over the years that they had known each other, they had been giving their own form of assistances. Some simple exchanges in information and other random helping of hands. They had asked each other favors a dozen times, but this would be the first Dumbledore would ever ask of Marian such a thing.

A favor not meant for the sake of their advantage against the Dark Lord who was slowly, but surely giving signs of his return, but for the sake of a muggle child.

"I want to take him in to Hogwarts at least for a year." Dumbledore stated. He knew Marian understood that it was a request. He was planning to take away a warrior after all.

Marian looked at him for a long moment, before turning away and stomping on his cigarette. "I thought your school only accepted those who where capable of magic?" The mans hand moved to the round object sitting atop his hat.

"It does." He replied.

"And you believe this brat can be a wizard too?" At this Dumbledore chuckled at Marians raised brow.

"Magic works in different ways, Marian. How that boy survived that attack all those years ago. How so many forms of power is present in this world." He stared back at the boy. "And I assure you that this child will be able to do our kind of magic." Marian just huffed again.

"His name is Allen Walker and I'm giving exactly one year. That's all I can allow." Dumbledore nodded. When he moved again to pick up the child, Marian's voice once again reached his ears.

"You never told me why, you know." Marian said a little offended. Dumbledore only smiled and gave the childs head a small pat.

"Because I believe it would be best for him to experience the hardships a child could ever have his age, before he experiences the ones we ourselves do."

Some useful information:

*This was unbeta-ed, so sorry for any grammatical or spelling mistakes.

*My writing style is quite chaotic so I will apologize in advance if it suddenly changes, which I hope it will not.

*I'm a slacker by nature so don't expect the next update to be so soon.

*This was intentionally short. It's only a prologue.

*About Allen not doing or saying anything…yeah…I think trauma can do that to a person

The idea came from knowing these few things. That (1) Mana adopted Allen when he was seven, (2) Mana died when he was ten, (3) Cross found Allen after Mana died and Allen stayed with him ever since, and (4) That ever time I watch the anime or read the manga, they only mention Allen being Cross' apprentice for three years.

So what happened to the other two?

Yep. That's where this story comes in, and if what actually happened is already established…well, lets pretend this it didn't for the sake of this plot.

Hope you enjoyed and thanks for reading! Also hoping I didn't turn them both too OOC. Actually, I'm hoping I didn't turn them OOC at all.
