Authorities are the special powers, abilities, and qualities that were attributed to gods, heroes, and demons, in myths and legends. They can range from physical abilities such as the superhuman strength of Hercules, to the speed of Hermes, to perceptual abilities such as Odin's all-seeing eye, and even weapons such as Thor's hammer Mjollnir.

Authorities may be stolen if the god possessing them is slain by a mortal, transforming that individual into a Campione.
