Once upon a time, shortly after Discord’s petrification, he perfected his last creation: free roaming Humans. The humans were feared by all pony kind because Discord had made them into the perfect predators. However, the Humans were given the gift of free will (nothing is more chaotic as a free will), and did not like to hunt ponies. A human village was developed on the outskirts of the Everfree forest, where Ponyville is now located. In this village lived the greatest hunter the world had ever known. However, while on a hunting expedition, a tragedy took place, and in order to survive, the hunter makes a deal with Tirek, swearing to serve him.
