Gyrefalcon's Marches is an area in Valdemar held by Lord Orthallen. During Selenay's reign the area came under persistent attack by an organized bandit army. In addition to destroying villages, killing men and women and plundering livestock, the bandits began stealing children. It was later discovered they were working with a band of slavers that were harrowing the fishing villages along Lake Evendim.
