Disclaimer: Anything from Xenogears or Harry Potter or anything else is not mine. This storyline is mine though, but anything used isn't. This is an AU Crossover story. You don't have to have played Xenogears or read Harry Potter to understand anything. If this offends anyone, sorry and e-mail me with either suggestions on how I can improve or why it affects you. Please bear with me, this is my first fan fiction and I'll probably revise or something if it sucks so R&R people.

Prologue: The Gears

In the beginning, man was created. 1000 years later, signs of intelligence were found in the majority of humans. Villages, even cities, were created to house and protect its inhabitants. One such village was to discover something that would change the world forever. This discovery was... magic. Magic was a major discovery and helped many people. However, not all accepted everywhere; people against this new form of energy separated themselves from the others and made clans that were filled with the people who despised its use.

These people became so obsessed with the extermination of magic everywhere, that some became desperate enough to use dark magic against the people they wanted to kill. Despite their efforts, the light side (I'll be calling the side that openly accepted magic the "light side" or something like that and the "dark side" (or something like that) will be their counterparts) prevailed again and again. There was one time in the past that the light side was truly endangered. It was after a site was excavated by the light side somewhere near the mountains of what is now in the Sierra Nevada. That was the day humans were exposed to the fact that there were people far more advanced than them. The dark side also discovered another site somewhere in the deserts of Mongolia in their search for power. Both sites had what were called 'gears'. These gears were huge machines that were even bigger than 5 grown men stacked together. Some were as big as skyscrapers, while some were as small as 1 meter. While some were humanoid, some were not. The sites looked like burial grounds for these machines, but in each site was a temple that was long abandoned.

Inside these temples were inscriptions, books, murals, and other machines that held the data to awaken these behemoths. The data also warned the humans that these machines were very powerful and could lead to the destruction of the users as well as the world. Each site had a fragmented data of the past when these gears ruled the earth and protected their users from dangers like dinosaurs. However, the users soon betrayed each other and fought for dominance with their gears. From this war emerged two victorious sides. One side was the side of good and the other was the side of evil. Hundreds of years passed by and the people soon forgot what they were fighting for and decided to make a truce to stop the bloodshed (but the dark side merely wanted time to recover). The light side, which saw this truce for what it was, accepted it, but during the celebration between the two sides, they launched a surprise attack to rid the world of evil.

The plan worked and the last of the evil clan died out. Because the light did not want this war to happen again, they buried these gears in unknown locations so that they may never be used again. Soon after that, an unfortunate incident occurred on the planet and destroyed the remnants of the good clan. The cause was still a mystery in the databases.

From this data, both sides realized that there were more gears to be found and searched again while their sages tried to decipher the rest of the data. A war was started for supremacy over the planet again. These gears were taken from their graves and with the newly discovered technology, repaired for battle. The humans waged a thousand year war until the both sides found new gears. These new gears were hardly fit for the name of being called gears. Their power was like that of the gods that the people of old worshipped and with this knowledge; they were called omni gears because of their unique specialties.

There was one gear that was mentioned in all the temples that were found; this gear was said to be a gear of pure power when at its fullest potential. The gear was dubbed 'Xenogear' in the data gathered, but its capabilities and origin were still shrouded in a gap in the timeline recorded. The gear was never found because both sides were busy fighting and sabotaging each other. When the war was over, the good side buried these gears in unknown regions with the hopes that they may never be used for war again.

They were wrong.
