I AM NOT FAMILIAR WITH CANON (yet) but I can take a stab at this. I'd cheerfully love to consolidate supernatural martial arts under the kingdom of Eblan, which canonically is ruled by ninjas.

Right now, the Eblan ninja clan is considering opening relations with the empire or at least some of its constituent kingdoms. It might be appropriate for Amon to belong to a different ninja clan within the kingdom, with a different agenda?
