Atlach-Nacha

A variety of abyssal monster that lurks deep underground where light doesn't reach. The illustration depicts a married individual, and an unmarried individual would appear like a female that gives a sharp impression with only four spider legs growing on her back. They do not stray outside their own territory and are focused intently on continuously building a spider web ad infinitum, but sometimes, humans who will become their prey show up underground, as if lured by something and finally manage to reach them.
