If i use the young harriers ability, does it only prevent my crane charactwrs from going from ordinary to dishonored, or does it also prevent them from going from honored to ordinary? And why?

So, here is where the distinction between "be dishonored" and "become dishonored" come into play.

Young Harrier (cannot be dishonored) prevents a stepping down of a character's personal honor. So, if they're already honored, they cannot go back to ordinary, and they cannot go from ordinary to dishonored either.

Contrast this with Steward of Law , who says "cannot become dishonored." This means that they CAN lose their Honored status to go back to ordinary, but cannot gain the Dishonored status.
