So I'm guessing, since it's a fantasy setting, that boats are generally made of wood? How large are these 'engines', and what is the smallest form used? Can Aether users utilize crystals in any way? make and/or charge them? What is the interaction between Aether users and Aether-infused weapons? Do the Sea of Ancients Researchers ever experiment with the application of Aether? If they only study the old, who studies the new? Oh, and what kind of stuff do the Divers in the Sea of Ancients dredge up? There's some fuel for the fire, eh?
