Mountain people of B----- who vanished many years ago.
Corbeau's father spent many years investigating the customs of the K—– people. They lived in a vast network of caves within the mountains surrounding G—–, and they survived off of mountain streams and springs as well as hunting local wildlife. They covered the walls of their caves with pictures depicting their history, religious beliefs, and possibly the reason for their disappearance as well. Stenfalk recalls a book his father owned, The Archer's Tales, which mentions this mysterious tribe.
Most people, except Corbeau and her father, believe that the K—– people are a myth.
