I might have something. Vesemir just focused on swords, daggers, a little with bows and crossbows, seeing as that was likely what was going to save us. Anything else was just a quick 'this is how you use this if it's literally all you have' kind of training.
Ah. Well. Vallo itself is generally safe, although the occasional angry thing finds its way to some kind of civilisation. Mostly it's dealing with whatever brought us here bringing other horrible things here, from necrophages to murder turkeys.
