So the Dalish get the Dales and the city elves get to carve out another part of Orlais?
I posted it in the Asunder thread I believe cause Lob wanted to know what my theory was. Yeah basically the CEs get their city state/country in the dales. Whether independent or part of the Orlesian Empire I don't know. Independence sounds like the best option, but I am not certain the CEs of Orlais actually want to be completely independent, plus there is the whole business that if they are part of Orlais, they have the protection of Orlais. As Celene puts it in ME, the CEs aren't elves, they are Orlesians. I think it could work.
As for the Dalish, if they ever are moved beyond the nomadic tribes they are currently, I think they will resettle the ruins of Arlathan which will conveniently be located in some sparsely or completely unpopulated section of Thedas we haven't been to yet.
I am far more certain that the CEs will get their territory then I am the dalish. I just am not convinced yet that the DA designers want to move away from the story and plot possibilities presented by keeping the dalish nomadic and infinite in the number of tribes they have. Granted, a restored kingdom of Arlathan would have its own possibilities plot wise.
