The irony is that Edvard's the one insisting on being in this position. Highmarch always fought to have the North let Fallangard be, but... we grew tired of them constantly helping Vix out against us, and them looting Winkamus was the last straw.
That's nonsense. Maybe Mathias didn't want to war them, but Caligus/north would've definately moved anyway. Highmarch is allowed to fight, but I doubt you actually decide on the targets.
