1810 England, the height of the Napoleonic wars. It was thought that humans walked the path of enlightenment leaving monsters and dark things behind. However, those monsters and night stalkers merely hide in the darkness, as a young maid, Bernadette, soon finds out.
In Croatian and Slovenian lore, a person born with a caul (piece of placenta covering their face) was destined to become either a Kudlak or a Kresnik. A person so destined to become a Kudlak would already begin a career of evil while still alive - his soul would leave his body at night in animal form and fly through the air to attack people or to magically do other harm to the community he lived in. Some stories say that they would become vampires or vampire-like beings. But if a person born with a caul became a Kresnik, he became a champion of the community. While he lived, his soul left his body in animal form at night to fight against both living and undead Kudlaks.
Where the Kresnik was the representative of goodness and light, the Kudlak symbolized evil and darkness.
