The last war didn't start until after Norland was dead.
Suville started on the non-Empire side, but quickly turned and attacked Carelia when Carelia didn't deliver a promised city to Carelia. Or something like that. Anyway, Suville wasn't really on the non-Empire side very much.
I joined the game midwar, so I can't say for sure how long Suville was an ally, but I would say at least 2 months after I joined. The deal was at the end of the war Carelia was to give each realm a duchy. Caergoth demanded theirs midwar before I joined and got it, then Suville demanded theirs. Suville got told no, because we were in the middle of the war and starting to lose so we could not just go and give them a duchy. So Suville flipped sides and CE and Suville looted the crap out of Carelia at the same time.
