"Wizards and common folk share one belief: witchers aren't much higher than animals. They're warped, bloodthirsty mutants who'll consume anything, even monster fluids, to curb their cravings.
But Vogel of Ban Ard had a very different picture of witchers.
Of course, no one could deny that the mutations witchers underwent affected their temperaments, immune systems, strength, and endurance. But you shouldn't mistake them for machines born to kill.
In fact, witchers had developed a distinct culture, specialized knowledge, training systems, and even their own code of honor.
They understood the effects of various organic and inorganic substances, and had some basic knowledge of magic: simple spells they called "Signs."
At first glance, all witchers looked alike. In truth, their fighting styles, training organizations, and worldviews differed greatly from one school to another.
The most famous witcher schools on the Continent were the School of the Wolf, the School of the Bear, the School of the Griffin, the School of the Viper, and the School of the Cat."
