Look, the train and wall options are going to take long enough (4 and 3 years) without Imperial Orders to speed things up (especially if we need to do other things, like overtimes or other Personal Actions) we Need to start them now otherwise we'll get locked into double imp-ordering something because we procrastinated. And as an experience procrastinator, I can tell you that cramming the Wall or the trains will be no bueno, but especially with the Hardbeak wall.
So again, my plan 'YO HO BITCH' covers for that all. Also that heist? The dice deities have blessed our Spy Ministry, and with a possible Omake bonus applied? Yeah, Maretonia's Nobles are about to be BROKE AF.
