A/N: I'm new here at Fan fiction, and have decided to try my hand at writing. This is a crossover, it is between Harry Potter and Yu-Gi-Oh. Many of the characters from the Yu-Gi-Oh series will make an appearance further through the story for the first few(4) it is mostly Harry Potter. This prologue takes place fifth year, not that I didn't like book six or five I actually thought they were the best, but to do what I want it would be too hard to write. After the prologue, and the next few chapters a year will pass and the story really begins when Harry would normally be getting ready to enter sixth year, so bear with me. Please read and review, hope you enjoy.

Rating: Teen. For innuendos every now and then, romance later, and violence.

Summary: Harry Potter discovers a new magic and during the summer receives a new title, the title of Dark Magician. He's taking the battle to Voldemort before it can start, and to help him is a teenager named Mana. YGO HP x-over

Harry Potter: The Dark Magician

Prologue:

"Wormtail." A cold malicious voice hissed from the confines of his throne. The throne was large a combination of silver and green, where the back would be was a giant life-like snake head. The snake had gory red eyes, and the teeth seemed to sparkle. This may have been because the snake was once alive.

The man Wormtail inched foreword slowly, his hands trembling, one could tell that his right hand seemed to be made of silver, which worked for him perfectly as he had a werewolf after him. He was a small man, watery, eyes, a nose like a rat, and small places on his head that seemed to be longer than the others. By this one could tell he had been losing hair, but it had begun to return, although he hadn't cut any of it yet. The man is no small way looked and acted like a rat.

"Master." Wormtail spoke in a squeaky voice, although it was no longer stuttering like it used to. It was becoming a harsher voice, if that is possible for one so squeaky.

"Wormtail, how goes the search?" The man hidden in shadows and sitting in the thrown asked Wormtail.

"It." The somewhat fat man hesitated before deciding telling the truth would be better. "It goes decent, my lord. Although we have not been able to find them yet, I assume it will only be a matter of time."

"This displeases me Wormtail." The man said harshly.

"I know, Master. But despite the slow progress we have discovered one thing of value.

"That would be?" The man hissed again though not as menacing as before.

"We have discovered that the item you seek is no longer just one item, it is more." Wormtail said trying not to flinch at the fury in his lord's eyes.

"WHAT?" The man screamed, the first sight of his face coming out of the shadows, and a long spidery white hand grasping the air angrily. The face was quite old and extremely pale, maybe even colorless besides white. The figure had blood red eyes and cat like pupils, and had curled around his neck an extremely large snake.

"It is as I said my lord. The item you seek seems to have been split many thousands of years ago. From what the death eaters in Egypt have told me, it seems as if it was split into seven possibly more, if the information we've found about it is true. Each item holds a fraction of the item when they were all combined, Dune believes that the item you seek has been split into at least seven items, however if his estimate is right then with the power the item contained it probably separated into ten to twelve items."

"So, the item has been split. This definitely puts a slow on things. Did the book tell you what these items look like?" The man who was the most fearsome dark lord of the age asked.

"Unfortunately no. It seems the author of the book was planning what you are trying as well, and someone seemed to get wind of what the author was up to and murdered him. The last thing he wrote was this.

"All my hard work is about to turn useless. I have discovered after numerable attempts at killing the Pharaoh and his guards, that the item which I seek is being divided. I've spent many long years learning the secret of the Ark, and now find out that all that is in vain. By noon today the item will be divided into at least ten items. One of the items I'm told shall be in the form of a golden eye, this information will be useless to me, if they are split. The Ark will never more be that which my design can be accomplished, perhaps a spell would be able to put it back together, but what spell could do this I can only dream. I have two hours before the Ark is separated, I have one last mission to fulfill. I have a feeling that I shall not succeed, and even more peculiar the fact that I will no longer be around. This is my last chance to retrieve the Ark, hopefully I will return to write of my success, if not my only hope is that someone else can eventually succeed even though I have not." Zakure.

"So there are at least ten items. Including that of a golden eye. This is very useful, Wormtail, not as much as I would hope, but useful just the same. You will be rewarded."

"Thank you, my master." Wormtail said giddily. The rewards given by the Dark Lord were exceptional, though usually with a side effect, it was how he got his silver hand.

"Of course. Has the search for the resting place been found yet?"

"As I mentioned before, it is in the process, Dune believes he will find it soon. If he is right however, only a chosen one can enter without death befalling them."

"I see." The Dark Lord paused a moment. "Then you shall be the one to enter it."

"W-what?" Wormtail whimpered pathetically.

"Just as I said you shall enter. First we'll send in a low rabble of a death eater, if they do die, then you get the honor of trying. If you succeed it means you are able to use one of the items, so my gift to you shall be the first item found, unless I say other wise. This shall be your reward. The honor of holding onto an item until the time it can be reformed into the mighty Ark."

"Thank you, my lord. I hope I do not fail." Wormtail said, although it came out in a hiccup.

"As do I, faithful followers like yourself are so hard to come by." The Dark Lord said carelessly. "Potter's birthday is today are the plans in motion?"

"My lord? I thought you were going to stay low for a while?"

"I've decided it's in my best interest to get rid of the brat before he can become a problem. We'll stage a break out at Azkaban and the rest of us will go and pay Potter a visit"

"Brilliant, my lord."

"Of course." The Dark Lord waved his hand dismissively. "Tell Dune to contact me, by the end of next month. If you can do that, then you're dismissed."

Many miles away a boy awoke to a sharp pain in his scar, and it took him only a moment to realize he wasn't alone.

A/N: First chapter, yes the millennium items are in here, though with a different background story and how they came to be, there's also more than seven. This takes place twenty minutes before July 31st. Please tell me what you think, anything is fine as long as it's constructive. Hope you enjoyed.
