Is there any point in the series where thunderstorms are present? Because I would gladly welcome the thunderstorms happening here in our country if I can connect it to Nobles or the others fighting (say, they happen to come to part of the Pacific Ocean near the Philippines while fighting. But of course, that's just me dreaming.)
Rajak and Kuharu's fight might be the closest right. The people on board a ship think it's not a thunderstorm (or lightning storm) but some other phenomenon though.
