Prior to the coming of the orcs to Azeroth, Moonbrook served as the focal point of the farmlands of Westfall. During the First War, Moonbrook and its sister town Goldshire were the final two towns to fall to the Horde prior to the razing of Stormwind Keep. It was rebuilt following the Alliance victory in the Second War.
Following successful efforts by the Defias to seize control of Westfall, Moonbrook was abandoned. It is currently controlled by the Defias, and is used by them to access their main base of operations, the Deadmines.
