Every story is true. Shadow hunters or Nephiligm have that motto for everything. Shadow hunters are the people who are trained to kill demons, they were created with the Mortal instrument, the cup of the angel. The angel made Demon hunters and a city for them. Down worlders are vampires, pixies, warlocks, wizards, and others. There are demons that kill mundanes, humans. Down worlders aren’t supposed to know about demon hunters. They use runes with their weapons to protect themselves, they appear like tattoos.
