The Counting House was a structure on the west side of the Palace of the Furnace Masters in the Foundry Glades. Slaves in the Counting House fared somewhat better than those miserable individuals who toiled in the Furnaces, but their existence was still harsh and cruel. They spent all their time hunched at little desks, meticulously recording figures of expenditure, revenue, and profit on barkscrolls.

Pinwick Krum was a clerk who worked in the Counting House.
