What areas of lore would you like to see more of?

[Megidolaon]

I'd like to explore aetherology, aetherochemistry, magitek, and cybernetics.

+1 to this, with an emphasis on aetherology and aetherochemistry.

I'd also like to know more about the physical and metaphysical properties of soul stones (as well as whether or not they contain a degree of sentiency) and crystals (the uses of deaspected and empty crystals, whether or not it's possible to 'refill' an empty crystal or tilt the balance contained in a deaspected one to one more desirable and whether or not it's possible to create synthetic crystal in a process akin to refining ceruleum).

I'm also hoping they explore the implications of Rowena owning a node fallen from Azys Lla and whether or not she uses it to read those tomestones she's said to be selling off...
