Congratulations. You are ready to embark upon the righteous and rewarding life of a Shadowhunter. We have been chosen by the angel to keep our world safe from evil creatures we call "Demons". And now you are one of us, and with this book, you will learn our lore and our ways. Angels, demons, faeries, vampires, werewolves, warlocks; they all exist, and they all must be managed and kept at peace. Welcome to our ranks, and study hard. This book will be the difference between life and death.
