Rangers of the North
Barad Calannon was the capital of Uivíril, one of the fiefdoms of Arthedain. Located at the northern end of the Emyn Sûl, the keep stands only fifty miles southeast of Fornost Erain, along the road called the Men Sûl. It has long since been abandoned and fallen into disrepair; who, or what, resides there now, no one can tell, though tales abound a-plenty.
The Lord of Barad Calannon also held dominion over three smaller towers spanning the ridges of the Weather Hills, one every twenty miles: Barad Thoron, Barad Ever, and Barad Narn. They are connected by a military road, an extension of the Men Sûl, that runs along the eastern slopes of the Emyn Sûl. It lies atop a series of dikes and terraces, the Rammas Sûl, intended to deter raiders from Eredoriath to the east. The dikes have eroded over the years since Arveleg I built them, and the Rammas Sûl can by bypassed at its southern end, because no permanent outpost has been constructed among the ruins on Weathertop.
Uivíril was, in sheer expanse, considered one of the largest fiefs in Arthedain; it included the Weather Hills, the Midgewater Marshes, the village of Occum on the Old Road, and the part of the Nan Túrath lying between the hills and the Old North Road.
