I assume you're already familiar with Trevor Henderson's Mystery Flesh Pit - I'm a fan of that and this reminds me a lot of that project... The Permian Basin Superorganism is widely known and (until 2007) celebrated in that timeline, and while known *about* nobody is sure of what/how/why it is (I have some suspicions about what Anodyne Industries knows 馃槰). I guess what I'm saying is that it's possible to know about something but still have a mystery, if that helps with what you're thinking about for this project. As for me, I'm very seriously thinking about a solo Liminal Horror Documentary Mode session because I'm a huge sucker for SCP-type "Roadside Picnic" paranatural shenanigans. 馃樃
EDIT: gaaaaaah I see from the book that I'm trying to teach you your business, and that's not what I intended! You know what you're doing and I'm content here to watch the show and clap quietly 馃
