There's no books man. This stuff is too new. But all the components are in place and exist.

This guy just demonstrated what's required to generate a theme, and it's not far off from extrapolating further from that in using a LLM to generate Lore and just some random maze generator to create the base control image.

Yeah. Show this to the Dwarf Fortress team. I hope they're already working on it anyway.

Doubtful. The developer is really old school. Additionally he's already spent years on integrating his huge lore generator into the fabric of the game. An LLM will throw a wrench into the whole process.
