March of Mandismoor
Located in the far northwestern corner of the kingdom, distant Mandismoor guards the road to Geoff. The lord of this frontier province is a renowned Knight of the Watch who is on constant vigil for incursions and other attacks from the north, particularly the Rushmoors, which are a constant bane. The infamous fortress of Ravonnar marks the northernmost extent of the march.
