Among the most common and weakest malicious spirits, rage demons are fueled by and attracted to rage. In the Fade, a rage demon’s true form is pure fire, its body seemingly made of amorphous lava, its eyes two pinpricks of baleful light radiating from its core. Their abilities are drawn from the fire they generate. Burning anyone who draws near, the most powerful can lash out with bolts of fire or firestorms that engulf entire areas.
