Dark Crystal game?
@fatefan There's a book called The World of the Dark Crystal. It's been out for decades. It has a whole lot of thematic...stuff to apply. And I'll bet that it gets reprinted now that Age of Resistance is out.
@reimesu I'll see if I can get ahold of it!
@fatefan Try the library. I'm also looking up The Dark Crystal to see what's out there and there's...a lot, actually. Creation myths and prequel stories and whatnot. But anything with Brian Froud's name attached will likely be original material, he's the one who created the world with Jim Henson. :)
