I haven't been around for too long, but the entire time I have, Morek and Luria have been pacifying to each other. I joined late 2012, and the only thing I've seen was a quick loot of Dongwei and a quick peace.
The main problem is, they can't march on each other. You can't war with capitals on either end of the island. How long would it take to even march from one capital to the first region of the other realm?
So just declare war and let nobles run a guerrilla war on each other, at their own leisure. No threat to the Kings, so no need to ban it. In any case, seems like Luria has its hands full at the moment, from what I hear (and hope)
