Since there was such a high need for ballistas and catapults in the old days of the civil war, a good quantity of seige engineers exist. usually at least one most large towns or cities. These ballistas are the most commonly manufactured type of siege engines in the continent, as they are very useful in attacking rocs, ship to ship naval battles, calvalry, and infantry (especially on plains or down hillsides).
They’re not in as much demand as they used to be, however, so most of the engineers have also diversified into building other things as well. The most common supplimental builds are ships (often equiped with ballistas), furniture, wagons, and housing.
