I like that idea. It adds a lot of flavor both for the agents and the monk troops.

You're almost certainly right about not having a ton of any particular agent (unless everyone wants to be a ninja ). Even if we get a lot of players Ninja and Metsuke number 2 is much more likely, and he's either working closely with the head guy, eyeing his position, or both.

However our other agents actions get funded could provide the recruitment and upkeep costs for the monk troops (their missions are free, anyway). Maybe their income is set by term, and any they don't use is lost?
