Prologue

An old run-down house, on the outskirts of London, seemed to be abandoned at first glance. But if one ever ventured inside on this summer night they would find evidence on the contrary. Past the entrance hall and up the old stairs, first room on the right, laying on an old bed, covered by a tattered blanket, was a boy.

The boy, no older then 16, was dressed in a purple robe. Matching hat, boots, and armor lay on the floor beside the bed. Shoulder length brown hair framed the tanned face. The boy stirred, his eyes fluttering before opening reluctantly.

Misty grey eyes cracked open, and the boy pushed himself into a sitting position. The mattress beneath him creaked and he shook his head, trying to figure out where he was. The boy's roving gaze landed on the figure of a gaunt black-haired man. Said man was slumped in a nearby chair, seeming to have fallen asleep. The eyes blinked once in confusion before the memories came back.

-Flashback-

The swirling black and purple mists dominated the dark landscape of the shadow realm, through the mists stumbled the figure of a man. He fell to the 'ground' seemingly stunned.

A pair of misty grey eyes looked upon the man with concern. The owner of said eyes kneeled down next to the stunned figure, brown hair falling over his face as he wondered how a human had made it into the Shadow Realm, without a Sennen Item no less.

The grey eyed man, known to the inhabitants of this Realm as the Dark Magician, set his green staff on the shadowy ground. He gently picked up the fallen man in his arms, determined to save the mortal from the shadows, which promised a fate worse then death.

Dark Magician, or Dark as some called him, muttered a spell, one that would show any hidden portals to the 'Real' world. For a portal was the only way a mortal could reach the shadow realm, without the use of a Sennen Item, and keep body and soul connected.

Dark located a portal not far from where the man had fallen. The mage studied the flux of renegade shadow magic; it would dissipate in less then a few minutes, sealing the Shadow Realm off from wherever it was connected to.

Dark glanced at the unconscious man in his arms and made up his mind, he heads straight for the vortex of energy and steps through.

The mage emerges from the shadow realm through a dark veil of cloth and found himself in a strange room. There were signs of a struggle, many things were knocked over and the place was a mess. Dark gently sets the man down on the floor of the room and turns to head back into the shadow realm.

The mage sighs half-heartedly, he didn't want to return to that grey place, but it was necessary. It was the only place where he could stay without having to seal his magic. For the mortal world could only handle so much dark magic.

He turns and walks back toward the veil, noting that the shadow magic caused it to flutter even when no wind was present. He noticed that the ripples in the cloth were becoming smaller, meaning that the portal was closing. The moment Dark passes the veil of black cloth he stumbles and blacks out.

-End Flashback-

The boy shook his head, trying to clear it of the images that kept flashing through his mind.

"Are you alright?"

The boy turns his grey eyes on the gaunt man and nods silently. The man blinks a few times, his haunted eyes blurred with exhaustion, he seemed to have just woken up, "I'm glad. It's the least I could do after you got me out of that dark place."

"The Shadow Realm...is not a place for mortals..."Replied the boy softly, "I could not leave you there, it is a fate worse then death."

The man fell silent, feeling slightly awkward after the boy's softly spoken statement. He shivered as he remembered the oppressive darkness of that world, he wondered what a sixteen year old had been doing in there.

The boy sensed the man's unease. A small smile lit his tanned face, "Still...I should thank you as well. You helped me after the portal closed. Now...I don't know what to do..."

"You want to go back there?" The man asked incredulously.

The boy closes his eyes, "I must. It is...the only place...I can truly be me."

"I still don't see why..."

The boy sighs, "You just don't understand. I don't belong in the 'real' world anymore. I am of the shadows. Returning to this world drains my energy. Forcing me into this younger form."

The man blinks, "You mean you aren't a human teenager? Who are you then?"

"I once was human...but I gave up my life in order to serve my Pharaoh...I am a Shadow Monster, the servant of the Pharaoh. The Dark Magician."

The man scowls, "You work for Voldemort?"

Dark's eyes narrow, "I serve none but the Pharaoh Atemu and his light Yugi."

The man's scowl vanishes but he still remains suspicious, "What shall you do until you return to that place?"

Dark sighs and lies back on the bed, "I don't know. I left my Staff in the Shadow Realm. Without it I cannot open a portal. Thus I am stuck here until I find an alternate route."

The man was silent for a moment before asking, "You say you lose your 'Shadow Magic' in this world correct?"

Dark nods. The man continues, "Then why not try learning another type? There is a very good magic school located here in England. I should know. I went to it when I was younger, and my godson is going to it now."

The transformed mage blinks, "You mean there is another type of magic besides that of the shadows? Maybe you are right. Maybe this new magic can help me home."

The man smiles, "Then do we have an agreement? I'll find a way to get you into that school...and you stay with me until it starts?"

At the boy's confused expression the man elaborates, "I've been very lonely lately...being an escaped renegade, even though I was an innocent one, means that I can't spend much time around anyone."

"What about your godson?"

"Well...he probably thinks I'm dead...I cannot contact him because I don't want to involve him...It was my fault he was almost killed..."

Dark smiles, "Alright...I'll stay but only on two conditions."

"What are they?"

"One, you teach me about this place."

"Alright...what is the other?"

Dark's grey eyes twinkle, "You tell me your name."

The man laughs, "That's easy enough. It's Sirius. Sirius Black."

A/N: n.n; I know I shouldn't be starting another story....but I at least wanted to put this idea down. I won't update this story unless I get reviews asking me too... or I finish one of my other three...or I get writers block on my other three...whichever comes first.

Also none of the other Yugioh characters are going to Hogwarts...except maybe Ryou. Though Yugi and the rest will show up eventually. This fic is mostly Mahaado(Dark Magician)-centered.

Also, there are no pairings because I can't think of any. I might listen to any suggestions..but I won't do any big romance. I'm just not good at it...Well anyways...review if you want me to continue.
