Well, I could always go behind Brance' back and try to raise an army of my own. Kind of like you did to help Virovene back in the day. Heh.
I did? I don't remember that. Unless you mean the time or two the Warders of the Island Citadel went over to fight some monsters. I guess I didn't really consider that "Behind anyone's back", though.
However, we *are* allied with Kabrinskia. And Astrum has never really claimed tight control over all of our noble's actions. They are generally free to come and go wherever and whenever they please, so long as we're not at war. If a few nobles of Astrum decided to vacation in he south of Kabrinskia, who am I to tell them not to? It's allied land, and Kabrinskia never asked us not to do so.
