How do you kill a monster? One that’s faster, stronger and more vicious than anything you’ve ever seen? You simply run, or hire a Witcher. In the times before the Goddesses, these professional monster killers hunted prey, nothing less than the most dangerous creatures known to the separate kingdoms of ponies. Yet, not all monsters are ravening beasts. Some are indeed ponies, toppling cities, and slaughtering innocents. But, no matter how hated or revered among the population, the tales of the long extinct Witchers were never forgotten.
