That's a possible angle yes, but I think the fey one is just more appealing. If you go in with the intent of banishing all the magic from the stolen lands then your ending with the LK is like 'ok just forget this ever happened' and then its over, you are another of the River Kingdoms. Meanwhile, creating an enchanted River Kingdom by allying either the LK or Nyrissa means you've gone beyond ancient Taldor's achievements in Verduran.Yes, you’re the civilizing force fighting to break the Stolen Lands out of that same repetitive, destructive (natural? unnatural?) cycle it’s been stuck in for a thousand iterations.
I'd even say that compared to the Commander in Wrath the baron of Kingmaker *earned* themselves a bunch of mythic ranks. First by defeating a spawn of rovagug, then a demigod, and then by becoming immortal lords of a magical land.
Now I can see myself playing an LN Abadarite that just tames the Stolen Lands but their town square is just too boring.
