A demon is an oft-malicious spirit from the Fade that embodies a sin or negative emotion and that feeds on the darker parts of the mortal psyche like rage, hunger, and desire. According to Solas, a spirit becomes a demon when denied its original purpose. This denial occurs when a spirit is forced to do something that greatly conflicts with its original nature, or it may occur as a spirit explores mortal minds and dreams and encounters negative thoughts and memories. A demon's strength and intelligence is dependent on the emotions or idea from which it feeds; the more complex the concept, the more powerful the demon.
