I'm not getting into the definitional argument here again, but I do want to point out, many of us wouldn't consider this a narrative or a change of narrative. I'm not saying, you shouldn't describe your campaigns this way, but I wouldn't agree with this premise that if a character rejects the duke's concern, and they go west, that means is a shift in narrative. I'd be much more likely to call it a shift in focus or direction of the campaign. It may seem pedantic, perhaps it is, but I also think when stylistic concerns are being raised, it matters
