Mai finally made good on all her talk. She brought me something I've never seen before, developed far beyond the borders of Cantha. It isn't clear how she got her hands on it, but I'm not going to press her on that. The device in question is a turret once fastened to an airship. It is powered by heating water, which powers a turbine to produce a current. All of that involves a massive casing. It's amazing the airship could fly at all. Mai took it strangely personally when I said the tech was unsophisticated. I've seen her work with much more complex systems, surely she is capable of recognizing mediocrity. I've asked if she thinks she can get her hands on more of it, and while she won't commit, she is optimistic.
