In 2008 scientist Dr. Robert E. Adams discovered the cure for heartworm. It was delivered in the form of a gas mask over the cat or dog for only a minute at a time. The gas would kill the heartworms at any stage of the development with only a side effect of a little bit of a runny nose. The best part was that it was so cheap that it could be offered as low as five dollars a treatment. Millions of pet owners around the world lined up for hours to save their animals, and in no time heartworms was just a thing of the past. To help prevent the outbreak of the killer worm again the US government hired teams of people who would go up and down streets spraying the gas. This way strays wouldn’t spread the worm onto other animals. It was perfect, maybe too perfect.

In 2010 a normally tame dog in a household suddenly started to viciously attack his owners. An elderly woman eventually died from the attack, and the dog had to be shot just to prevent any more harm. It was a puzzling case as no evidence of rabies was found in the male dog. However, what the vet did find was an odd type of brain cell in the dog. It was attacking other cells around it, and it was triggering massive overdoses of adrenaline. A few days later three other dogs, in the same area, did the exact same thing. This time a young child was killed. The odd thing was that his body was eaten completely; even some of the bones were gone. The two other dogs were found with the same type of odd cell in their brains.

Two weeks later chaos erupted. Dogs in every city and in every state were attacking anything they could get their mouths on. Some said that they acted almost like they were rabid. Experts on rabies gathered a few of the infected dogs and came to a terrifying conclusion. Since the odd brain cell was producing so much adrenaline the canines were in a constant state of ‘super’ strength. Although, this came with a terrible cost so the dogs were always in search of food. The treatment for heartworms that was found two years prior had been slowly mutating until it finally took a hold of the dog. The total death count for humans throughout the entire world was reaching the hundred thousand. Military teams were called in from the government to eliminate any dogs in sight.

One organization started to offer to pick up dogs that had never come in contact with the medication. Often it was in third world countries, or in small towns where the medication never got that far out. A small scan would be done on the dog before it was picked up and shipped off to a town located on the southern boundaries of Canada. This town was named Nexo, the mouth of death, and it once was a booming city full of people. Now it sits and it’s the last place for dogs to live a semi-normal life again.
