Turiel is a fallen Watcher in the ancient apocryphal text known as the Book of Enoch. In later translations, he is one of the 20 leaders of 200 fallen angels, mentioned eighteenth. The name is believed to originate from tuwr "rock" and El "God". His meaning has been translated to be either "Mountain of God" or "Rock of God".
After his fall, Turiel took the form of a Snow Leopard and to this day still reigns over the mountains. It is because of this that he caused the indigenous people of Asia as well as the Himalayan, to see the Snow Leopard as a messenger or even an avatar of the deities that reside within the mountains or are the mountains themselves.
