Prologue: A Wicked Damsel, and a Wizard in Distress

Harry woke to the sound of a mad-max reject banging a tire iron on the Blue Beetle's hood.

"Hey!"

The supremely filthy (and presumably fragrant) man jumped in surprise and and began rapidly fiddling with one of the many straps adorning his person.

"What the hell do you think you're-"

It was at this point that Harry stopped, having noticed that the object the leather-bound interloper was currently unlimbering from his back looked suspiciously like a grenade launcher.

Reflexes given wings by adrenaline had his .357 out and firing in the time it took him to blink in surprise. While three magnum rounds through the chest seemed sufficient to deter the man from further vandalism, the noise also seemed to have alerted his friends.

Five dead biker wannabes (lacking the prerequisite motorcycles) and several dozen new bullet-holes in his car later (courtesy of the aforementioned assholes), Harry and Mouse were standing in the middle of the road, surrounded by a howling dust storm coming off the salt flats to the north, glaring angrily at a cheerful wooden sign, situated in the midst of what had probably been a truck stop in some bygone era, which read: "Welcome to Nevada".

Azula woke to an unholy cacophony that could only be the secret bastard love-child of a thunderstorm and an artillery barrage going through its rebellious teenage phase. Rolling onto her side to remove her face from reeking stained upholstery, the Princess (not for the first time) swore undying vengeance unto the third generation against whomever had invented straight jackets. And her brother, as long as she was at it. And her uncle, just to be safe.

Upon getting as clear a view of her surroundings as possible, given their cramped nature, she quickly determined that what little she could see did not please her in the slightest. She was lying on a bench in the back of what appeared to be some kind of tank that had been refitted for luxury transport, then thoroughly destroyed by time and neglect, followed far more recently by significant quantities of flying shrapnel. The only positive things she could say about the situation were that the noise had stopped, and that she no longer appeared to be in the asylum.

"Bullshit."

Mouse tilted his head inquiringly.

"One does not simply wake up in Nevada with no idea how they got there, surrounded by feral bikers."

Mouse continued to gaze at him levely.

"Ok fine, that might happen to some people, but it really shouldn't be happening to me. I don't drink nearly enough."

Mouse just chuffed quietly and pushed his head under Harry's hand for some well deserved petting and ear-rubs.

"Dammit, if shit like this is gonna keep happening to me, I should at least be given enough warning to get appropriately hammered first."

Mouse grunted happily, and leaned against Harry's leg, causing the grown man to stumble sideways under the Tibetan Masstif's massive hairy bulk.

Harry was cut off by a series of loud thumps emitted from the back of the Blue Beetle. Revolver drawn, he crept over to the passenger side of the car, and wrenched open the back door.

"Well this is certainly a new experience." The wizard drawled. "And I thought the dead bikers would be a pain in the ass to explain to the police."

I'm just going to get this one out of the way. As the title and summary might imply, this is going to be a Massively Multiplayer crossover. Bonus points if you can guess what universe Harry and Azula are in right now, but a few others you can expect to see are Big Trouble in Little China, Percy Jackson, and the Marvel Cinematic Universe. Now you may have come to the conclusion by now that this won't be a particularly serious story. No. No it will not (I wouldn't personally call it crack, seeing as it has a plot, but some of you may disagree). Cheers.

PS. Timeline-wise, this takes place about a year after Sozin's Comet, and directly between Turn Coat and Changes.
