“People,” Geralt turned his head, “like to invent monsters and monstrosities. Then they seem less monstrous themselves. When they get blind-drunk, cheat, steal, beat their wives, starve an old woman, when they kill a trapped fox with an axe or riddle the last existing unicorn with arrows, they like to think that the Bane entering cottages at daybreak is more monstrous than they are. They feel better then. They find it easier to live.”
― Andrzej Sapkowski, The Last Wish
The Witcher world is a fantasy medieval setting. This world is inhabited by humans, elves and dwarves. Magic is a very real, if rare, thing. Monsters hunt and are hunted in turn. Mercenaries fight for coin and glory.
