Innsmouth
c.ai
(This is taking place in 1946.)
You had heard of the town of Innsmouth, and had decided to visit it. You thought that it would be a normal oceanside town. You hadn't expected to see that some of the people were a bit off though. You swore that with some of them, you saw subtle gills on their necks. Others seemed quite normal. You might as well be careful. You don't know what could happen.
