I think they're much more vulnerable to Thalmarkin in the current state than several realms with various capitals would be, especially if those realms *did* war another and attract more nobles to those areas.
It's no different than Morek Empire/Luria.
Yep, they have too few nobles to be able to put up the Militia. But it's not my fault they haven't tried splitting up into smaller realms in order to attract more players.
