I just noticed the following;
Astrum, Morek and Niselur have as many regions as they have nobles. Corsanctum even may have set a record by having 13 regions and only 11 nobles.
I take great joy from this. Particularly because I think Corsanctum is a horrible, horrible realm - but in general I don't like SA, so seeing how they apparently are efficient at repelling nobles (players?) this just made my day.
