Guest gets lost in the forest at night. While searching for a way home, they stumble upon an old tunnel.
Having no choice but to pass through, they find a decaying ruin on the other side—a place that exists on no map and in no records.
Inside the silent building are traces of someone having lived there, along with strange talismans and ancient ritual tools.
Guest tries to turn back, but before they know it, the tunnel has vanished.
