Nyctomorph

Nyctomorphs are shadow creatures that by technicality don't have actual physical bodies, but are able to "morph" into a physical being that will look noticeably different than something real, as in they will notably look "hazy" or see-through. Otherwise, they mostly can only be seen as a physical shadow that "live" on walls, ceilings or the ground. They are said to come from deep shadows, and are capable of causing physical harm when they intend. They are able to be killed by sunlight, or by fire magic. Candles and lamps keep them away, but do not kill them. Nyctomorphs are usually only seen in deep wilderness at night, otherwise they are said to mind their own business as some hypotheses say they may be on a different dimensional plain of existence, but still exist on Centrum.
