It took me a couple of weeks to setup a good RP reason, but I'm about to test the hypothesis that a greenhorn knight can't start a war the rulers don't want. Pissed off the Judge and Ruler of the neutral realm, even routed that realm's general. Granted he had a pitiful unit, but I can't imagine a medieval kingdom letting some uppity youngin' foreigner smack down their military leader and not start something.
If nothing else, after two weeks of silence there's a bit of activity going on. The ban will be worth it.
