So, like Sombre, I see the progression of Ermor as reasonable. It's fine, then a bit corrupted by death magic, then totally destroyed.

Marverni is essentially the pre-occupation Gauls and Celts, EA Ulm the Germanic tribes. By MA, Ermor has conquered them, and then declined so that Ulm, Marignon and Pythium have broken away. Marverni presumably either remains occupied or is no longer important. Ulm is Germanic again, only much further on in their history - it's a medieval rather than barbaric theme. Marignon is France/Spain in the Inquisition, and Pythium is Byzantium. Sorted!
