Right. Well, that being made clear... I'm not thrilled with the idea of leaving our bodyguards behind, which leaves out the cavalry options. It seems like the 3rd is going to run into something that Asarnil will be nuking while Gustav blows it to shit with cannons anyway, so while there might be an investigation to be done there they're likely to come to the conclusion "dragonfire will solve this problem" and be right to do so, whether we're there with sage wizardly advice or not. Which leaves the 4th; low intensity combat plus a little bit of poking at things to solve a mystery, with Van Hal if we're lucky. That seems like it'll ease us into the war in a way that plays to our strengths.
