To kill a Unicorn is to bring bad luck and the hatred of nature itself down upon the foolish. It is said that the mate of a unicorn that is murdered will turn horrible in it’s pain and anger, turning against nature to hunt and kill the murderer of it’s mate. It turns dark and soulless and seeks nothing but the death of it’s enemy.
