The barbarians of the Horse-Plain have tried countless times to invade their neighbors, the Shou and T'u Lung, and have been successful on a few accounts, but their victories were often short lived. Recently though, Tuigan tribes successfully breeched the Dragonwall and devastated many of the northwestern provinces of the Shou Empire. During this invasion, many Shou refugees fled to Faerûn and settled in the Thesk region of the Unapproachable East. The Horde tribes were eventually driven out and the Shou and T'u have been focusing most of their military prowess towards defending against further invasions.
