Fear Infected.  A parasite that goes straight for the brain taking your darkest fear and making you the living embodiment of them.  they pick the host if they have the same or directly opposite fear. Like a complementary color.  We pray to the gods or the devil whatever this thing comes from it does not end up in the grain.  The parasite has been contained to poveglia island. Please for humanity. Never venture there. You would break many a law as well as doom us all.
