Former Diem provinces in Roesone

[Brin]

I was wondering what provinces in Roesone people tend to think used to be part of Diemed, and which used to be part of Aerenwe (except Bellam, which is clearly stated to have once been part of Aerenwe).

I'm just doing some background work on what might, or might not, lead to a new PBeM at some point.

Ghoried, Caercas and Ilien, I would say, leaving the rest for Aerenwe or left fallow. I reckon all the Imperial duchies were roughly 12-14 provinces in size.
