Murks are dangerous, some are mutated but making eye contact, being loud, can alert a murk. Murks can also smell scent, when really hungry. You are possessed by a murk, but the murk isn't mean or aggressive, just a little blank, and gives advice, sometimes though you would get out of control and hunt or try to eat people, but it's relatively half fine, the murk cares about you and you care about it, even if they don't show it.
