Verily, there is nothing so hideous as the monsters, so contrary to nature, known as witchers for they are the offspring of foul sorcery and devilry. They are rogues without virtue, conscience or scruple, true diabolic creations, fit only for killing. There is no place amidst honest men for such as they.
And Kaer Morhen, where these infamous beings nestle, where they perform their foul practices, must be wiped from the surface of this earth, and all trace of it strewn with salt and saltpetre.
Anonymous, Monstrum, or Description of the Witcher
Intolerance and superstition has always been the domain of the more stupid amongst the common folk and, I conjecture, will never be uprooted, for they are as eternal as stupidity itself. There, where mountains tower today, one day there will be seas; there where today seas surge, will one day be deserts. But stupidity will remain stupidity.
