The most powerful Void entities that have manifested in Aethara are those that absorbed not just the concept of hunger, but the concepts of *hierarchy*, *dominion*, and *cruelty as art*. Pit fiend lieutenants are the commanders of fiendish intrusions --- beings of terrible intelligence and martial prowess that organise lesser fiends into disciplined forces. They are strategy given flesh: armored in dark chitin that resembles plate armor, wielding weapons forged from calcified Void matter, and commanding enough arcane power to match a seasoned wizard. They do not emerge from fractures randomly --- their arrival signals a deliberate, coordinated assault by whatever passes for authority in the Void.
