That could open the way to a new challenge...
The Dwarven Recruitment Station Challenge
You and your six administrative assistants will dig out a self-sufficient kiosk in the area. New recruits will arrive, procure their basic weapons (crossbows and wood bolts, but metal weapons and armor a plus), and be sent out to battle immediately. You may keep the occasional veteran or metalworker on hand only if it directly helps your recruits gain a fighting chance (i.e. keeping the road open and outfitting them properly.)
