He flipped through a book of dragon knowledge illustrations written by humans and learned that each dragon would collect caves full of golden treasures, use fiery dragon breath to fight human knights holding shields and swords, or fly to the kingdom's castle to capture a beautiful princess.

Why do dragons fight endlessly with humans? He didn't understand it at first.
