That’s very interesting. I am from and live in New Orleans in Louisiana where there are still people who practice Voodoo and other similar practices. There is a range from tourist version /completely fake to half serious to deadly serious people. Far more of the former than the latter.
Most practitioners don’t realize that some of what they are into is from the Old World so to speak, like the Gris Gris contains diagrams from the Picatrix.
I have a HEMA buddy in Portugal, up north in Lisbon. He’s also a fan of some of my Codex writing though he’s only read one of the history books. I’m not sure if he plays RPGs but I know he does war games. We have talked about doing another history book about the early Portuguese adventures in the Pacific Rim in the early 16th Century. That would be a big project though.
