Chapter 1

Allen shivered, he was wandering yet again on a cold, winter night with Mana who noticed his shiver and smiled warmly at him. The young boy smiled back at the person he had come to know as his father and almost immediately forgot about the cold surrounding him. After all, how could he be cold when he had him most treasured person with him?

While Allen had forgotten about the cold, his body hadn't, so when a rather strong gust of crisp, chilly air blew with him right in the center. He shivered violently and looked up for Mana who was a few paces in front of him. He tried to catch up but the wind was too strong and kept pushing him back.

"Mana!" He shouted with wide eyes that pleaded for help.

His foster father paused and looked at him before turning back to walk towards him. Allen let out a sigh of relief, Mana wouldn't leave him.

"We'll always be together, won't we Mana?" Allen asked for the hundredth time. However, Mana showed no signs of being irritated by the often repeated question instead he smiled widely and nodded.

"We'll always be together, Allen." He reassured, and once he was in front of said boy, he offered his hand that Allen eagerly latched on to.

They continued walking hand in hand for the rest of the night as the wind blew making them nothing more but silhouettes.

Around midnight, Mana stiffened and paused in the middle of park they were walking through glancing around as though searching for someone to Allen's shock. He was usually the one to stop, not Mana. In fact, Allen had never seen his foster father stop walking once they started, unless it was to perform.

Allen tugged the hand he was holding effectively catching the attention of the taller man who looked at him with a blank face before recognizing who it was. "What it is, Allen?"

"Did you find the person you were searching for?" The young boy answered. He had concluded that Mana had seen his lost brother that he was always searching for.

Mana stared at him for a minute or two as though it was the first time he had actually seen Allen. Once upon a time, Allen might've been worried, but he had already seen this happen more times than he could count, so he had assumed it was normal for people to do this.

His father opened his mouth only for a voice to interrupt him, "I've finally found you, Mana!"

Mana turned quickly but not before Allen saw the madness in the eyes he had often searched for comfort and forgiveness, and yelled out, "You killed Neah! You killed my baby brother!"

The haughty laugh made Allen look at whoever had interrupted Mana. The first thing he saw was the ever present grin that seemed to stretch more than humanly possible, then he saw the top hat that hid the upper-half of his face. It was only after that he took in the rather round shape of him. He was gently floating down with an open umbrella and once he touched the ground he closed the umbrella.

Allen, not knowing what was going on, moved closer towards Mana but his movement caught the attention of the person who had just landed.

"Oh! Who is this little fellow?" He sang, tilting his head to get a better look at Allen.

Allen glanced at Mana for help but his foster father ignored him. "Allen Walker. Who are you?"

"How rude of me, not introducing myself. I am the Millennium Earl and I will be the one to kill you and your precious Mana."

This event scarred Allen for the rest of his life.

Cross didn't consider himself to be normal but several people would, for example, the nearby liquor store owner, his neighbors, and women. While he wouldn't consider himself normal, he tried to keep up a rather normal facade, and was succeeding at it. So far no one had looked at him too weird, and he planned to keep it that way.

But, as fate would have it, normality soon left Cross Marian in the form of a child.

Christmas was just around the corner and the red-haired man in the car was cursing the snow that was falling at a rather fast speed almost like a blizzard. "Damn snow! Now I can't get my hands on that good wine! Damn it!"

He punched the steering wheel and a honk made itself known making several others drivers look at him. Be normal! He reminded himself, be normal. The stares soon found somewhere else to look as Cross could no longer feel them digging into his back.

After a couple more minutes, he gave up on waiting for the snow to be shoveled and with difficulty turned the car around. He hoped that there was something he liked on the TV, because now he couldn't get himself drunk on the wine he had been planning to buy.

Surprisingly, there was something good but it didn't last long. The show was interrupted for some breaking news.

"Owls have been spotted flying in places where they are not native to…" Here they showed a picture of owls perched on houses and mailboxes. Cross turned off the TV, having already heard what they were saying from his messenger, Timcampy, and he didn't like to hear things twice.

After that he tried different things to keep himself busy a while the snow kept piling outside. He talked to some beautiful woman, drank some not-so good champagne, and read a book he found laying around the house. The book, unsurprisingly, was rather boring to him and so halfway through it, he fell asleep.

Tiedoll was having a difficult day and it was not improving. First, Kanda had a tantrum about not wanting to be called Yuu and Marie hadn't been able to calm him. So he had been called to help and he had by saying "would you rather be called my adorable son by me?" Kanda had immediately surrendered not wanting to be called such a thing by an "old man".

Second, the Earl was killing to many innocent wizards-to-be. Hogwarts, or the Black Order, as many of the students called it, was losing the fight against him, and the ministry of magic was panicking. Which was never good as it made them lose all rational thoughts, and this was showing; they had ordered all third-years and up to fight against the Earl. Tiedoll was not pleased, he was angry. They were practically sending his students to their death.

Last, but not least, when taking a walk to clear his mind, he stumbled upon a young boy who was lying unconscious next to a middle aged man who had clearly been killed by the Earl. In fact, he had thought the child was dead too, but upon closer inspection, Tiedoll saw his arm twitching. He had quickly taken off his coat and wrapped it around the child, who was cold to the touch. Once he was back at Hogwarts, he had the head nurse look over him.

"He'll be fine once he gets some rest but make sure he stays warm." She said sternly and Tiedoll nodded but she wasn't done, "However, there is this scar on his face" the head nurse moved to where he can see it "but it shouldn't cause him any trouble once it heals."

Tiedoll eyes widened. The scar was shaped like a pentacle and was around his left eye. It was red as though it had just been made but it wasn't bleeding, at least not at the moment. Tiedoll frowned and leaned closer, he really needed to get glasses. There seemed to blood smeared on the side of his head like the boy had tried to wipe the crimson liquid off.

"So my guess is that it was made earlier today. Am I right?" He guessed.

The head nurse nodded once before saying, "It seemed to have healed rather quickly though. And is it true that his companion was killed by the Earl? If so why wasn't he killed as well, Tiedoll?"

"I'm not so sure myself," he pondered shaking his head slightly before continuing, "but I think that the reason he wasn't killed by the Millennium Earl is connected to that scar of his."

Tiedoll made sure he was grabbing Marie and Kanda, who was holding onto a sleeping child who appeared to be a few years younger than him, before swishing the wand in his hand and chanting two words. They soon disappeared before appearing on the corner of Privet Drive.

A cat soon walked up to him out of seemingly nowhere and nudged him successfully getting his attention. He looked down before crouching to pet the ginger cat. Kanda noticing what he was doing frowned and muttered, "crazy old cat man." Marie, hearing what he said, stifled a laugh and once he had regained the use of his vocal cords asked, "Where are we?"

"We are at Privet Drive." He paused and stood up causing a couple of his joints to pop, "Which is where the infamous Marian Cross is living for now."

Knowing what question they were going to ask next, he wordlessly pointed the house that had the number four on the mailbox. In unison, his students looked at the house before thinking, this doesn't look like much.

While they were turned around, the tabby that Tiedoll had been petting slowly transformed into the form of a woman. This development made Tiedoll chuckle quietly as he could not wait to see his younger student react.

When they turned back to face Tiedoll, Kanda jumped up, startled, while Marie's eyes widened slightly. There was a lady swathed in a white dress that seemed to have an unearthly glow making her a ghost in Kanda's eyes.

"Ghost!" He shouted, pointing at the lady. Marie put his hand on Kanda's shoulder and shook his head when the younger boy looked at him. "Then what is she?"

"Not what, who?" Marie corrected him, patiently. Kanda scowled but still corrected himself, "Tch. Who is she?"

Marie smiled, "She is Hevlaska."

While Kanda was still confused on who she was, he shrugged as though he understood.

Tiedoll watched his students interact with a small satisfied smile before turning back to speak with Hevlaska. "What did you think?"

"It's not a good place for him. All he thinks of is liquor and woman, it's atrocious to think we are sending a mere child to live with him." She said frowning concerned for the now sleeping boy. "Do we really have to send him here?"

"It's our only option unless we want him to grow up spoiled and Cross will keep him safe. You know this." He sighed and walked towards the white haired child. Once Tiedoll reached the said boy, he carried him up to the house he had pointed to earlier. Then Tiedoll deposited him at the front porch which was covered in snow.

He walked back to the group of people who were waiting for him and whispered, "Good luck," hoping that something would go right for someone even if it wasn't him before vanishing along with everyone else on Privet Drive.

On that night with the stars gazing at Allen Walker and the snow falling towards him, some people celebrated the demise of their enemy while others slept soundly in the comfort of their beds. And on that night, Allen Walker knew not that he was cursed, or famous, he only knew the warmth of the coat he had been wrapped in and the letter clutched in his hand. He most certainly did not know that he would wake up to the sound of Cross cursing a certain headmaster.

So for the people who haven't figured it out, this is an AU. And things are going to change in the Harry Potter timeline too.
