For species, I have an old head-canon race who inhabit a planet formed entirely of dark matter (soft sci fi so I assume this is alright for a new wiki) that are formed of and feed off of the emotional energy created by the inhabitants of their galaxy. While the "fear-based" variations would work well in a horror universe, there are others types that represent an emotion each as to avoid the whole "planet of hats" trope. While they can feed directly from their planet due to it's properties, the hungrier and those who require more energy would probably hunt down and remain in proximity to large sources, feeding on but not leaving the source dry. What i'm thinking is protraying the "negative types" (Anger, Greed, Fear) as ravenous groups of monsters that use their power and other abilities such as trickery and shape-shifting to ensight large doses of emotion in their targets wich they then proceed to feed off of, causing brain damage and, in many cases, leaving nothing left, only a catatonic host unable to feel or interact but aware of everything. Living death if you will. Or cause their behaviour to alter violently, insanity or any number of things that would push death lower and lower on the list of worst things that could happen to you.
