Firstly, thank you for the response.

I think I'll pitch the concept (which has rapidly taken on a life of it's own and is scaring me, just a tad, because of that). The main role of these lords and ladies are, as I understand it, to challenge the demon lord and priestess, and force unity. With that in mind, there are many types of challenges-martial, physical, challenges to bloodline, politics...the like.

But a challenge to morality is something I'd be most interested in, not in the sense of temptation precisely-but what fascinated me about the Ikko-Ikki was the challenge they posed, historically to the system-a different ideal of religion, a different ideal of government and lord-peasant relations. Even if their portrayal in media is somewhat inaccurate.

So ideally, this lord would pose the same kind of challenge-an enemy to the established practices and governments of the land-meaning he has reason to oppose the demon lord half of the priestess/demon lord pairing and to target them-a lord's a lord, a lord after all. But by the same token, he'd likely be opposing the other demon lords as well-opening up possible "enemy mine" situations with the main pairing-be it with this lord or against him.

Basically, someone in the villain's role who is not, in and of himself, villainous. Who challenges the heroes both physically, in battle, politically, as he opposes the system that the Demon Lord part of the pairing is related too, or at least, born of, and finally, morally and ethically-he's not a bad man, but one they'll still end up fighting, possibly killing. Which, in and of itself, brings sorrow to the story, and could strengthen or weaken the bond between the main pairing accordingly. 

Hope I'm making sense.
