I'm alone in a old house in rural Minnesota. There's creatures living in this house, let's call them bats. Bats have been known to forcibly enter my living space, but they have not been a problem since late summer.

I hear them. Above my skull and within my life. Creeping and scratching. Probing for weakness.

I shall not let this end in my defeat. I down a potion of strength. The scraping grows louder.

Nothing can kill me. I am eternal.
