" There are now, to the delight of parasitical writers like me, what I might almost call “public domain” plot items. There are dragons, and magic users, and far horizons, and quests, and items of power, and weird cities. There’s the kind of scenery that we would have had on earth if only God had had the money. "

― Terry Pratchett , A Slip of the Keyboard: Collected Non-Fiction
