So, earlier today, a new story idea popped into my head. And I decided to write the prologue of the story. It's kinda funny because it is pretty much, word for word, how the idea came to me in the first place. I don't know if I will continue this past this point but I do have a fair few ideas as to where I could go with this. At this point, my priority is the Parallel Worlds storyline that I am writing but if I ever reach a brick wall when writing that, I'll fall back onto this instead. But feel free to tell me what you think of this idea and whether or not you think it sounds interesting. So, without further stalling, I present the prologue to 'Immune' (working title).

How far is too far? How good of an improvement is too good? In 2052 humanity reached something that was just that, an improvement that caused more ruin than anything else in history. Some of the Earth's top scientists and geneticists developed a cure to every known viral infection and harmful bacteria. This was something that had been in development for many years and was seen as such a gigantic breakthrough when it came out. Everywhere had access to it, it was especially given access to countries that are known for having many deaths due to viruses and bacteria, it was a huge success. The best part or what became the worst part was that it was a one time deal and then every one of your future children would have the immunity too, eventually, this would mean that every person living on the planet would be immune. Everything was good, except doctors and those doing research, they lost out big time but everyone else was great.

In January of 2116, a meteorite was on a direct course for impact with the Earth. No one really worried though as it was believed that it was too small to actually crash and would burn up in the upper atmosphere, being nothing but dust by the time it reached the surface. This assumption was drastically wrong. Instead of burning up, the meteorite went through the atmosphere without a problem before exploding while still falling. This sent debris flying every which way imaginable and many people came into contact with the small pieces of rock that fell from the heavens.

And this was the scenario humanity faced. An immunity to every known virus and harmful bacteria and a meteorite that nearly everyone came into contact with. It would have been fine if it weren't for what was on the meteorite. You see, living on the surface was a form of biological life, one we had never encountered before. Initially, we believed it safe but quickly found out about its viral properties. It was like a parasite in many ways, choosing a host before modifying their genetics so the bodies cells would create more of the virus. It would also modify the brain functions, shutting down all unnecessary things and leaving only the natural instincts to fight or flee danger, to feed, to sleep, to procreate and to defecate. In layman's terms, it made one a zombie. This infection was quickly found in many people who were then quarantined but some escaped or some were overlooked as, within mere weeks of the first case, most of the globe was infected.

This was twenty years ago. For an outside viewer, one may say that the impact it has had on the globe has been largely positive with many forms of wildlife growing in numbers to the point where most endangered species were now well within stable numbers. The amount of grassland had expanded drastically, leaving plenty of space for the increased wildlife to thrive. But humans still existed, in a way. Granted they were all in this zombified state but it seemed to be a lot better for the world. The zombies had seemed to develop their own, very primitive, society. Somehow they even managed to hold relationships with one another in order to give birth to new children, each one already being infected in their mother's womb, something that meant the survival rate for many mothers was very low. It had been clear what had caused this infection to spread so easily and quickly; the immunity vaccine. By making humans natural immune to things that would have previously made us ill or were fatal, their immune systems became lazy, no longer having any function. All those early years of human evolution it took to develop an immune system were wasted.

There were few known people on the entire planet who were left unaffected. One of these was a woman who would wander endlessly, searching for food in order to assure her survival. She didn't know why she was unaffected by the virus like most were, she didn't even know her name, she wasn't even sure if she had a name. She had just woken up one day in a room made of pristine white walls and a thick metal door, a door that had stood wide open. She knew how to talk too, something that she never knew how she knew, not that she ever questioned it. She had only ever talked to two other people, her friends that followed her; Clare and Aiden. But unbeknownst to her, she had a great destiny to fulfil, for she was now humanity's final chance for long term survival.
