Cryptid

Cryptids are creatures from folklore or legend.

Background
Cryptids were part of local superstitions and the topic of folklore, serving as town and school mascots. In Point Pleasant, a museum was dedicated to a cryptid known as the Mothman. The Vault-Tec University named their sports team the "Fighting Wendigos."

A group called the Truth Seekers were dedicated to cryptid hunting in Appalachia before the war, meeting monthly to discuss their current progress. Their reports included a "lumbering hairy beast" near Grafton, which was debunked as an old mine cart filled with dirty laundry and a sighting near Uncanny Caverns that ended up being an albino bear.
