The town of Artakam skinned and sliced those few monsters to the bone. People were more than willing to put some work in, as they were quite bored here, and they'd love to kill the time; It also helped that they were all hungry!
Even the ex-mages who felt sick because of the invisible, poisonous air, pulled themselves together for a moment, just to lend a hand. Food helped them feel better, and eating the flesh of the enemy certainly gave them a sense of pride.
In terms of the overall workforce, however, the three-thousand naturally powerless people in town did most of the work. The air didn't bother them, so the work they were putting in today, made them feel as if they were back in the old world. There was nothing that a bored person couldn't do.
