Fienden Beings (Fiends)

Fiends are horrifying monsters that vary in appearence, but all of whom are wholly evil. They are overgrown demons with size, strength and speed on their side. They do not feel empathy, love or remorse. They are powerful engines of destruction and death, and they hunt after all that is good and pure. They are extremely dangerous and they are the reason humanity almost went extinct. They cannot be reasoned with, except amongst each other. Close studies of their behavior suggests some of them possessing very high intelligence and problem solving. This coupled with their ability to communicate via telepathy allows them to coordinate attacks with bestial brutality and some degree of basic strategy. They spread disease and are very difficult to kill. They appeared very suddenly and are believed to be from the depths of hell itself, as their biology does not match that of any mortal animal. When fiends communicate telepathically to humans, they do so through intrusive and unpleasant psychic voices inside ones own mind. Some people who possess psychic sensitivity can hear their voices from afar and sense their approach. Merely being in their presence can cause severe nausea, a state of pure terror and even miscarriage in women. Unbeknownst to most scholars, they are not just mindless monsters. They are escaped zealot prisoners from the underworld who are dedicated to a prophecy from a time long forgotten.
