"Brigitte, what did you learn from the Atlanteans?" I'm glad you asked! The answer is a LOT. The first part is a bunch of chemistry that I won't bore you to sleep with, but I'll keep it short by saying they use controlled electrolysis to superheat metals like magnesium, which in turn function as the heat of an above-water forge! But that's not where it ends! They can either forge something entirely with this superheated metal (in excess of 5000 °F if they want!) or coat
something else with it. That latter part is what I spent a lot of time learning. Imagine crafting armor or weapons out of wood, or porcelain, or even just bone or coral, then coating it with a lightweight but extremely durable metal outer shell. The applications are staggering! I'm hoping to set up a regular exchange with them :D
Oh and also my workshop from home showed up a few weeks ago, literally right behind the smithy. So you haven't been imagining that the place is nearly four times as large now. This means I have plenty of room to try and replicate what I've learned or build new feats of engineering! I'm pretty excited, someone may need to check on me from time to time to make sure I've remembered to eat!
