(A/N) I've lost inspiration for two of my stories unfortunately, so while they're on hiatus I decided I'd get this story started. This is one of my latest ideas and it's a little different from my others. Being different due to the fact that I'll be accepting OC requests from all of you, I usually directly ask other authors if I can use their characters, so this is new to me. I'll have more info at the end of this chapter, so just read through this to get a little more backstory on the story itself before deciding if you'd like to make a request.

Corruption: Prologue

The heat in the desert was blistering, the sand almost appeared to glow under suns rays. A lone figure stumbled their way across the desert floor, hunched forwards, a hand clutching the left side of their belly. The bullet that had caused the wound, still lodged in their gut. Sepsis had sank in some time ago, the bile and bacteria created a horrible infection within the cavity. In turn, creating a terrible stench to go with it. The last of the figures strength finally gave out, sending them crashing to sand below. One final breath escaped their throat, and then they fell still.

"And another one bites the dust," a voice sighed.

Across from the recently deceased, atop a dead, hollow tree log, sat another figure. The figure was a man, a human by the name of, Connor Jenkins. He wore a black leather jacket, a white long sleeve shirt, grey cargo pants and black boots. His left arm and right leg were made of metal rather than flesh, his right eye was a cybernetic replacement. In his metal left hand he held a single cigarette, slowly twirling it around his fingers. In his right was a lighter which he opened and lit up and then extinguished by closing the lid, repeating the process several times.

"So, where to begin," Connor said, standing up from his seat. "I suppose we should start where every story does, at the beginning."

It didn't start off so bad, and we never expected anything to come of it. Our scientists had been experimenting with technology related to dimensional travel, it wasn't unheard of amongst some of Mobius' science groups, we did after all have the Star Posts. The last thing we expected though, was for them to accidentally open a portal. What happened next was a surprise to everyone, quite honestly the last thing we expected. Out from the portal walked a creature, a pony of all things. Now we have all sorts of species as far as the Mobian race goes, ponies and such included. But this one didn't walk on its hind leg like most beings of Mobius, this particular pony walked its way through the portal on all fours. Another pony walked through the portal after it, and then another. Soon we had six of them standing before our rather surprised scientists. Four of them were clad in armor, carrying swords with themselves. The other two must have been scientists or researchers themselves, carrying clipboards and other equipment for documenting observations and such. One of our scientists were first to speak, giving a rather uncertain greeting and enquiring as to who our new 'guests' were. The ponies replied in a surprisingly polite manner. Manners and such must have been quite a big deal where they came from. Soon a full blown conversation began between our group and theirs.

As it turned out, our pony visitors were conducting experiments on dimensional travel themselves. They too had opened up a portal by accident, though they had been the first to travel through the said portal. Had it been me, I would have closed the bastard up and never spoken of it again. But I'm not a scientist and I wasn't there, so allow me to continue explaining these events of the past. Everyone managed to come to a reasonable conclusion in the end. We found that due to both our respective worlds experimenting with dimensional travel at the same time, we must have created a link between us. Thus creating the portal that had inadvertently come into creation.

Both of our civilizations got along rather well to be honest. So you can stick all those movies where people from two different worlds become instant enemies. For almost a year and a half, everything seemed well enough. We traded knowledge that had been passed down through the generations, technology that made our lives easier to live, love even blossomed between some of us. We were happy, we were at peace and we were constantly moving forwards. As with all good things though, it sadly didn't last forever. It was small at first, hardly even noticeable. A rock here, a tree there. But then everyone woke up one morning and found Cloudsdale floating in the skies of Mobius. The realization that something was wrong was instantaneous. What in the hell was Cloudsdale doing in Mobius? Is what we all asked. It didn't belong there, it belonged in Equestria. The next day came and we found a city from Mobius known as, Everglades, sitting on the outskirts of Manehattan. Our scientists immediately got to work, pony, Mobian and Human alike. Nothing else shifted around for the next few days, and that was when we discovered exactly what was going on. It appeared our two worlds were merging together, slowly becoming one.

That may not have seemed so bad to some, but take a closer look and you might realize just how bad shit was about to get. This was never meant to happen, it shouldn't be happening. The amount energy being expelled as our two worlds merged was phenomenal, and the levels were only rising. It was deduced that this could end up being to much for either of our homes to take. In other words, it was likely that both of our worlds would end up being obliterated after they had fully merged into one. So, as you'd expect, actions were taken. Absolutely anyone who could help in any way did just that, we were determined to put a stop to this before the endgame played out. At first we tried closing the portal that had been opened at the very beginning, a reasonable way to go when you think about it. But any attempt to do so proved futile, the energy being expelled strengthened the portal, making it impossible to close it. I don't remember much of what happened after that, but the one thing I do know, is that we failed.

These days we refer to the event as, The Merging. We had originally thought it would destroy us all, well, I guess we were half right. It was like a bomb went off the day it happened, I can barely describe how it felt. The wind rushing against my body, the heat from the explosion of energy, it was truly an incredible thing. I dragged myself out of the rubble when I came to again, everything around me had practically been turned into a wasteland. I can't remember how long I had to walk before I found any other signs of life. Three, maybe four days. It didn't help that I was in a rather remote part of the world when the shit hit the fan. All I wanted to know, was how much had survived The Merging, how much had been left standing. Thousands had died in the blast, many cities had been reduced to rubble, adding to the wasteland that lay before us. Incredibly though, many people had survived and a number of cities and villages had been left standing. It was miracle in its own right, but something seemed... off. Nothing happened at first, but then the evidence of change slowly broke through the seams.

People had changed. Old friends became new enemies, brothers and sisters turned on one another. The Merging had brought something else to the surface, The Corruption, as I like to call it. The changes weren't extremely noticeable, it simply shifted ones point of view. It was mostly evident within the Princesses of Equestria, the sisters of day and night, Celestia and Luna. Both believed in peace amongst all residents of this newly created world, unfortunately they didn't agree on how said peace could be brought about. Celestia believed in freedom amongst all individuals, no one would hold any more power than the person next to them. Luna didn't understand these ideas, she couldn't grasp how one would deal with crime or anything of the sort if there was no one with the power to keep control of these problems. Luna had many more arguments for her sister ideas, none of which pleased Celestia in the slightest. Luna's ideas were entirely the opposite of her sisters. She felt order could be kept by giving varying levels of power to certain individuals, the higher your rank the more power you would hold. This could work, if it weren't for the fact that the higher ups were immune to any form of law. There was large risk that these individuals may abuse their power, suffering no consequences in the process. Riots would likely start and chaos would befall upon the world. The sisters split ties, forming their own factions. The Celestial Empire and The Lunar Dominion.

War quickly began between the two factions, Celestia put her ideas of freedom on hold for a time being, a military would need ranks in order to function properly. Neither factions achieved any lasting form of victory for a long time, either would win one battle only to lose the next. Many died during the ongoing conflicts, but the last thing anyone expected was for the two sisters to perish. In one of the greatest battles our world had seen, Celestia and Luna fought to the death in the skies above the war below. When the fighting came to a close and the smoke slowly began to clear, the two sisters lay lifeless on the ground. The factions took the bodies of their respective Princess home with them, putting them to rest and creating a memorial for remembrance. The fighting continued, even after those who had started it had passed away. This is how it has been for quite some time, an endless war between two groups, fighting for the same prize only with different ideals.

Peoples ideals weren't the only thing that changed. It was well known that some Mobians possessed different forms of powers, unfortunately for some, they found themselves stripped of these said powers. Over time, it was discovered that the only person left holding the power of super speed was none other than, Sonic the Hedgehog.

Some people disappeared amongst all the chaos, just vanished one day. A group of ponies who had been dubbed, the Mane Six, were some of such people. We have no idea where they went, they just seemed to up and vanish. We tried to find them, but to no avail.

Connor placed the cigarette he'd been holding in his mouth and lit it up, taking a long drag as he put his lighter away. He exhaled slowly, most of the smoke expelled out of his mouth though a small amount seemed to rise from his chest. He let out a quiet hum as he flicked the spot on his chest, where the smoke came from, a couple of times.

"You know, I always had a saying," Connor said, looking down at a skeleton in the sand in front of his feet. "The only people who see the end of war are the dead. I never thought I'd become part of that saying."

The majority of the Skelton was bone, though its left arm and right leg were made of steel, exactly like Connors. A cybernetic eye lay in the sand next to it. A number of the skeletons ribs were cracked and fractured, a single bullet resting in the middle of it all.

"There's just one thing you need to ask yourself now," Connor explained, looking up from the sand and staring straight at you. "What is it you fight for? Power? Or freedom?"

(A/N) Now that I've given you the basics of the story, let me know your thoughts. This is also a point where you can send me your OC's for the story. There's a few things I need to bring up before you send any characters in. So, first up. As far as powers go, I'd like to ask everyone to keep it simple. So really just one form of power. Fire, ice, chaos, whatever you'd like. And do try to keep it in the Sonic universe please.

The second bit is about numbers. I'm looking at taking eight OC's all up, so four characters for each faction. Now just to clear something up, neither group could really be considered the villains of the story. So feel free to give me the side you'd prefer to be a part of, but remember that I won't be favoring either side so it really won't matter to much. There's also a slight possibility that I may include character deaths, that means peoples OC's. I haven't completely decided on that yet, so this is really just a warning of sorts. Who gets in and who doesn't will simply be a case of, first in first served.

And finally and most importantly, I will be accepting OC's through PM ONLY. Any characters put in the reviews will be ignored entirely. If you don't have an account, well them I'm afraid that's just to bad.

That's pretty much everything I can think of, if I forgot anything then I'll bring it up another time. I'd like to hear your thoughts on this rather than receive a character from you and nothing else, so if you can spare the time then I'd appreciate if you'd leave a review and let me know what you think if this. So until next time.

Catchya :)
