Prologue

"In the void, there was a vial. One drop was deadly. Instead of killing you, it destroys you. Slowly. Painfully. But not everything. It destroys your bones, and replaces them with flesh. Flesh that if you rip it open, it will not heal. Quite the opposite actually. It will stay destroyed. But every piece of blood has been infused with that vial if you drink it. And so, even if there was just a medium piece of flesh left, it could still manage to move, and has only one piece of will to survive: demigods...

If you want to destroy the demigod that drank the vial completely, the best thing to do is to burn it. That seemed to be the smart thing to do, that people will think of after a few minutes. But that's the thing. They can't burn. They'll indulge the flickering flames. They'll heal by themselves. All their wounds you caused will close up. And it'll quadruple their strength. Make them stronger.

They call themselves the infected. The name fitted them perfectly. How you infect the others is not the same by how it started. You bite them to infect the demigods that are not infected. And when they get bitten, kill them unless you want to be dead. You'll be lucky if the zombie just eats everything. It's hard to kill your friends if they're zombies. Bite them anywhere, anytime. When I say anytime, I mean anytime. They come out in the daylight. In the night. So when I say anytime. I mean 24 hour hunting for demigods.

After the demigod gets infected, it's best to kill them immediately. You don't get the luxury of waiting for an hour to say "goodbye" and start crying. If you want to survive. Don't say anything. Be emotionless. And if you want to know why, read the next sentence. They'll turn almost immediately. You get 1 minute. Only 1 minute before the infusion starts. There are no sign of symptoms since they turn in 1 minute.

I bet some of you are scrolling down and ignoring all this advice from above. Athena would be ashamed. Let me tell you how they can turn in 1 minute. The first things you get to experience are your screams of pain in your ears as you get bitten. It's painful. After the infected has savored some of your flesh, they wait. Some impatient ones can eat you up just like that. Now if you haven't been killed by one of the demigods yet, you're unlucky. It's better to die than to be an infected. It's more painful to turn into one.

The next step is your eyes. They'll be bloodshot, a bit like red eyes, but much worse. The pupil in your eye will disappear, and your entire eye will be filled with red. No black or white left. Just red.

Your skin itself will not become red. It will not become green either. And it will not rot. It will become pale. Deathly pale. Almost like a solid ghost. Except much, much worse.

The outer body will stay the same. Except for the deathly pale skin, nothing has really changed that much. It's the inner part of your body that will affect you the most. There are no bones. No heart. No lungs. None of those things inside your body in need of survival. The only thing there was blood and flesh. Those are the only things you need, to survive being an infected.

The parts that people are always destroying are the head and the brain. Yes, that can be true. But in this case, that's not possible. Let's take a look at the head first. Removing the head usually kills a zombie in most zombie movies. In this case not. Every type of flesh- even the tiny bits that are on the floor due to a person chapping the arm off- has the will to survive. It's in their blood. Their flesh. Those tiny pieces can move. Even without the head, they are perfectly capable of moving. Looking like worms doing so. It could be based on worms. And how can they infect others with only a piece of flesh you may probably ask? They get to you if you're sleeping. Crawl inside your mouth- destroying the tiny piece of an infected flesh- but making a new, fresh infected.

Now let's go on to the brain. The part that usually kills every piece of infected or zombie in the movies or books. Unfortunately in this case, too bad if you're prepared for this moment of infection. Those movies and books won't help you at all. Destroying the brain will be useless. It's a miracle if you even do manage to get to the brain. It will, however, lower down their intelligence level by a lot. I'll say about 50 percent.

Now coming to the infected behavior, that's a hard one, but I'll describe it to you in the best possible way. They're vicious. And I don't mean vicious as- let's just say- Lucas the vicious dog. Ok, I just made that name up, but seriously, they are much more vicious and have no mercy while eating flesh. They bite. Eat. And search for many other demigods.

Saying their intelligence level is hard. I would say it has a lot of common sense. It can light a fire, know when someone is near. It has as much intelligence as a human, so calling it 'stupid' would be, well stupid. Do not underestimate them. Never underestimate your opponents. That's one lesson you'll learn when this fiasco happens.

I am not doing this for drama, but here I go at saying this: The vial cannot be destroyed. If Chaos the creator of the universe- and sadly the vial as well- destroys it, the glass that contains the vial, will shatter into a million pieces. And the vial itself? The drops of the liquid or substance will fall into Earth. And with the demigod's luck, right into someone's smuggled drink. And with they're luck. It did.

Now I bet you're all wondering how you kill them. That's what you're all waiting for right? Well I have no answer for that one. I am sorry, but there is no answer, no cure, no ambrosia or nectar can cure the infected. You simply cannot destroy the infected. Hate to break it out to you but there it is. Just to make my message clear, I'll repeat it one more time. They are unstoppable, they cannot be defeated. It is a lost cause. I gave you all the information I have. You're on your own soldier..."

A/N: Should this be T or M rated? And also, who do you think should start the infection? No main characters at the moment, and no OC's.
