Since the Dark Ages, when werewolves, mermaids, goblins, brownies lived together with people, each of us carries in our blood fragments of the genomes of relict races. Most cope with the dark part of their soul relatively easily, having driven the ghosts of the past to the very bottom of the subconscious; someone needs the help of the Church or a psychoanalyst, someone drowns out the voice of someone else’s blood with vodka and drugs...
