RPG CAMPAIGN TOUR CHALLENGE 2026 Day 20-Are there any mysteries as yet unsolved?

 Legendary tales, lost civilizations, or cryptid creatures; does the setting have anything for the amateur detective?

The main mystery I have currently set up is "What's going on with Hupa?" There are certainly details to be established in a lot of places that could qualify as mysteries, but a lot of this is still in development until it's needed for a scenario.

Even though I have established that Sasquatch are real, I have not touched on other potential cryptids that might or might not be real in the setting.
