Noctus

Often known as hell's thieves, and for good reason, the Noctus are a respected proponent of occult circles if not through their demonstrable skill in espionage, then by fear of their malice. They hail from a world enslaved by the forces of darkness, meaning their souls are damned before they are born in exchange for their natural prowess. They are trained from birth in the ways of the thief, assassin, and monster hunter and are deployed by the rebel angels to strike sensitive targets and reign in rebels of their own mortal forces. Many who leave their world on business stay there as freelancers that are still loyal to hell, while others desert after their initial mission and follow their own path. Some even actively go on to resent their former masters and hunt their mortal cults on Earth.
