Rage demon

Demons can exist in both the real world (through possession) and in the Fade. Demons spend their time searching out new territory and pushing their boundaries. For this reason, they are the Fade dwellers most commonly seen in the mortal realm. While in the Fade, demons rail at a sleeper, forcing them into dark realms of nightmare where the demons feed off the negative energy created by their fear.
