The dark-coated Wolf wandered through the forest, if such nightly prowls could truly be considered wanderings. It had been ten years since The Fall. The Zombie plague came, wiping out ninety percent of the world's population. Ten percent of seven point one billion is still a lot of people, some would say. Of course, those who would say that are without a doubt among the hordes of slouching, moaning monstrosities who were once human. In the Age of the Undead, pessimism is a survival trait and optimism isn't. The bulk of humanity is dead and gone for the most part. Here and there, ragtag bands of humans hide, forever hunted by those who used to be their fathers and mothers, husbands and wives, brothers and sisters, sons and daughters. Welcome to the twenty-first century.
In this day and age, many humans succumb to the madness that comes from inhabiting a world without hope. A world where the dead walk and the living, whose numbers dwindle day by day, must hide. The Wolf knew these things but didn't process them the way a human being might. In the world of wolves, there were predators and prey. And absolutely nothing in between. Living in a world suddenly filled with swarms of slow-moving, fearless and utterly mindless Undead monstrosities didn't even come close to phasing the Wolf. Just as its kind had done since time immemorial, it would hunt and be hunted. That was all. The Wolf found the deer it had been stalking for the past three days. Finally, it pounced on the beast, ripped out its throat and feasted.
Even while feasting the Wolf kept its senses on high alert. After the Fall, scores of animals once kept in zoos or as pets had escaped from the confines of captivity. There were gigantic snakes roaming all over the woodlands of North America. The descendants of pythons and boas once kept in zoos or as pets by humans long since dead or worse, reanimated. These magnificent ophidians had done really well in the post-apocalyptic remnants of America, Canada and Mexico. Of course, they shared their world with the descendants of lions and tigers, as well elephants and rhinos escaped from zoos and circuses after the events of the Fall. The fauna of North America was wonderfully diverse these days. All kinds of predators roamed the wilderness. And of course, all of them feared only one thing. The millions upon millions of Undead walking and moaning across the continent. The Wolf instinctively knew all this. That's why it kept its ears to the ground. It feasted as fast as it could, for it knew it wouldn't be alone for long. The scent of fresh blood always attracted the Zombies. Always.
The Wolf's hackles raised when it heard the telltale signs of a Zombie presence. Twigs snapping. Fetid smell. And of course, the constant moaning. One good thing about the Zombies is that they always made plenty of noise wherever they went. In nature, most predators knew that silence was golden. Zombies didn't need stealth, nor did they need speed. They had the advantage of numbers. And they hunted animals and humans across every continent on God's green Earth. Zombies also roamed along the bottom of the ocean floor, fighting against sharks, orcas and other marine predators for the schools of fish. Everywhere, mammals, birds, reptiles and even insects found that in the aftermath of mankind's near-extinction, they had a new enemy.
Across the savannahs of Africa, the deserts of the Middle East and the European tundra, wild beasts fought against the Zombie hordes. Entire herds of elephants found themselves surrounded by the remnants of Undead men...and consumed. Prides of lions fought the Undead, and lost. Schools of sharks took on the Zombies, and perished. The thing about Zombies is that while utterly dim, they feel no fear, no pain, and they also never stop. They will walk across a lake of fire to get at their prey. They will swim to the bottom of the ocean to feed on every last fish left. The world's animals were simply unprepared to deal with such monstrosities. The only breed of animal that did well against the Undead is known as the common North American Wolf. And our Wolfish hero, Gray, is a prime example of this breed.
