I was thinking of going a bit silly and thinking up a revolutionary new spice that's sweeping the continent. Mithril is common and boring so it's not even worth mentioning.

Or maybe kicking in that idea we had about using the same world to tell fantasy, modern, and science fiction stories. I want to make something similar to FF7 where magic is a resource and uses orbs... The same old idea I've had for ages. I should really hammer that idea out more. It's only been like a decade and a half since I thought of it lol
