How are they on a peace-lock...? They've been at war, and have not been on friendly terms in a while.
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?
