I didn't understand what you meant about Railag... please explain!
Well, it's just that your cousin Isabel clearly wants a romance with her. But we know that Railag and Isabel are together. I'm just thinking in terms of a scenario category (or even a campaign), and immediately such passions arise, like in Shakespeare.

Although, if you just make a campaign with the confrontation between Haven and Dungeon, the plot is not bad. And I can't think of anything better right now.
