@HarmlessDave I hope it leans in to more of the "Overpowered Protagonist deals with sometimes humorous slice-of-life situations."
We have a zany cast. Several of them seem to have some sort of awkward feelings for him. We also just got his two previous teammates in town. Are they going to join the guard, too? Is the knight vice-captain going to get blow-back from her boss?
That knight captain is destined to be trouble down the line.
Anyone that can be defeated in a straight-forward fight is easy, but plenty of things can't just be punched or blocked. Between the knight captain's distaste for the guards and the knight vice-captain's feelings for Seig, there's definitely material for another novel -- and without drawing out a monster-of-the-week type of situation.
I mean, the Capital is regularly attacked. We're likely to see more attacks. But that could easily be used as a tool to play for timing and importance with the other stuff going on.
Even if the Capital weren't attacked anymore, that would also be disruptive to the Capital as it would be a change from the status quo. It would mean it is safer and more folks would engage in trade there. This would bring a steady new stream of potential problems.
