The aptly named Vigil is the seat of the Watcher-Lord. The high spires of Castle Overwatch afford a commanding view of the bloodsoaked westward plains on the Belkzen frontier, as well as the mist-shrouded highlands of Ustalav to the north. The horsemasters of Vigil breed and train the mighty destriers and swift coursers that bear Lastwall’s finest into battle, and the pastures around Vigil are known for the quality of their bloodlines. Vigil also hosts the Crusader War College, where crusader tacticians have worked to best marshal magical and military resources to defeat their numerically superior enemies.
