Yup, it's already been done too. Hasland split into the Protectorate which was Norland, Hasland, and Southasland. That's when CE went nuts and got a bunch of other realms together and went after them. Norland had a leadership change (Draco or Drago took over) and started to attack as well. If they hadn't of switched it would've been an interesting fight, as it was the loss of one of the members was too much and I lost.
*sigh* I haven't really ever had the urge to build another empire since. But hey! We did pioneer a bunch of fun stuff back then that are now game code.
