((For firearms, that was just me derp-ing, sorry. I keep thinking in terms of 18th century rather than 20th century. They probably wouldn't actually have full howitzers on them(the height+recoil=leverage isn't exactly good for structural integrity, fine craftdwarfship or no) though mortars could probably fit. They're big, and seem bigger than they are, but at most, maybe 5 meters around. Meant to be a bit archaic compared to the main territories perhaps, but not far behind, and they have advancements in other areas instead. But yeah, it's not a full on fortress, just a walled town(it's the biggest settlement in a rather important mountain pass, after all...)))
Jaster settles down, berating himself internally for being so ridiculous. All the same, he is relieved that no lynch mobs were waiting...well, time to trawl the city for an inn that won't try to kill Gerruce. Usually takes most of the day anyway, but in a town this large, he shouldn't have to sleep in the gutter, at least. Unlike some places...
