Nobody is hiding anything.

The world does not need a conspiracy.

It has tired witnesses. Bad light. A village that has had a difficult few years. A noise that everyone agrees must be the river.

The impossible happens. People find an ordinary place to put it. Then they go back to work.

The rules are usually correct.

Do not whistle after dark. Listen to the grandmother. Listen to the person who has lived here longest.

The explanation may be nonsense. The prohibition may save your life. Dismissing one because of the other is a mistake the records have seen before.

The names are less reliable.

Vampire. Ghoul. Demon. Words frightened people already possessed. A heading is not an understanding.

Four hundred years of records. Hundreds of names. There are still doors that a prepared hunter opens only once.

The world is exactly as you remember it.
It simply has holes in it.
