When Worlds Collide by AJMarx

First, the part we all hate.

Disclaimers and introductions. This 'chapter' wont be relevant to the story. It's my go to page for when people try to sue me. I advise you not to skip it, as it will hold information about the setting and pre-story plot which is essential to understanding this story. Thank You.

Disclaimer: This is a crossover fanfiction which will in-cooperate plot, characters, and specific text of the mangas XxxHolic, Tsubasa Reservoir Chronicles, and X/1999, and some of their animated counterparts, all of which are created by CLAMP and belong to their respective owners. Although it is not necessary to have read all of the mangas listed above, it is highly recommended. This story will contain spoilers for the entire plot of all of them and their associated animes and mangas, which includes Tokyo Babylon and XxxHolic Rei. Again, all of these stories, plot, characters, and other forms of productions belong to CLAMP and their other respective owners, not myself. There are no non-canon pairings, although there are currently subtle allusions to Kamui/Fumma, and Fai/Kurogane pairings, but no more so than the mangas. Rated T for mature content, blood, literal gore, and strong figurative language. This rating is liable to change to M if the feel of the story becomes darker, or pairings become more obvious. Also, if you are against, or simply dislike reading, same-sex pairings, I suggest that you pick another story because there is a high chance this story will develop one of those. Please do not criticize my work based purely on that or other aspects which contradict your own personal bias. Please note for critique that I do not have a beta.

Summary and Pre-Story:

TRC: Syaoran, Fai, and Kurogane have been traveling with Mokona for six months since returning to Clow Country with Sakura. They have been moving around frequently, because Syaoran agreed to never stay in the same place for more than 14 days (the number of days he stayed in Clow Country for originally times two, for Watanuki). They are looking a way to create bodies for the clones, while Kurogane is also looking for a way to return the rest of Fai's power to him. Fai's eyes each have unique properties; one of them increases his power each time he uses his magic, while the other draws power from his lifeforce.

3XH: Watanuki has inherited the shop from Yuuko. As she did, he employs Fuuma (from TRC) to deliver or collect wishes, and aids the TRC gang, as well as the Vampire Twins, through Mokona and other methods. Domeki also works in the shop. Watanuki currently is the one keeping the crystal form of Fai's power. In recent years, he has become curious about Yuuko's past, and is attempting to collect information from her previous clientele about her. He has also begun to enlist the TRC crew's aid in granting wishes in exchange for information which Yuuko left him about the clones.

X/1999: The Dragons of Heaven and Earth are at war. Subaru, recently made Sakurazukamori, has been attempting to contact Yuuko, an old friend and mentor, about a way to grant both Kamui's and Fuuma's wishes, or resovle the war in a way which would benefit both parties. Kamui has yet to release the seal on the Holy Swords. All of the characters besides Seishiro are alive.

Others:

-Ashura-ou, the child of the King of Celes, is roaming worlds thanks to the now-dead Fei-Wang, looking for the ones who destroy Celes and killed the King.

-Fuuma and Seishiro, the brothers, are traveling separately through the worlds. Fuuma is running errands for Watanuki, looking for something which is equal to his wish. Seishiro is continuing his hunt of the Vampire Twins, and looking for something which will allow him continuous use of his eye. The Twins are running through various worlds, avoiding Seishiro.

-As all of Sakura's feathers have been returned except for the one under Tokyo, dimensional travel is now affected by other powers, such as magical ability. As our heroes travel, they are more likely to run into each other.
