Angels are winged celestial beings who serve as the messengers of God, guardians of his creations, and soldiers in his eternal war against the denizens of Hell. They are the parent race of many species found in the Shadow World. It was the angel Raziel, an angel of high rank, which started the race of Shadowhunters by mixing his blood into the Mortal Cup and having humans drink from it.
Very little is known about Angels:
- The higher rank they are, the larger they are. Raziel is said to be 50 feet tall.
- Angels are encased in golden skin and cannot be seen with the naked eye.
- Angels will smite those who summon them.
