Teeth of the North

The Teeth of the North are a line of large standing stones that extend from the Great Bend region of the Caldar River all the way east to the sea, a distance of more than 400 miles. This line of stones runs perfectly east-west and is comprised of exactly 880 standing stones spaced exactly 800 yards apart (2,400 feet). Of the 880 stones, 71 of them have fallen over (or been knocked over by forces unknown) and only 11 of those have broken. The stone they are made from has never been identified with any consensus, but it is a smooth, glass-like stone and the height of the stones seems to be uniformly set at 28' from top to bottom, although much of that total height is hidden by the portions of the stones that are buried underground. There are 19 places along the length of the line of stones where a portion of an ancient road can be seen uncovered be wind or water, and as a result it has long been speculated that the stones are a part of a much larger structure that includes a paved road 35' wide with a crown in the center of 15' that would allow water to shed to either side in the event of rain. In every instance where the road is exposed and soil and debris has been removed, the road continues unbroken under the ground. All evidence indicates that the stones are part of the extant roadway and that the two are inextricably linked somehow.   Since the founding of the Kingdom of Imesse more than 230 years ago, the Teeth have demarked the border between Imesse (and specifically the Kingdom of Lesser Imesse since 209 AF) and the Kingdom of Aria.   All current understanding about who (or what) erected the stones and built the road indicates that it was the same beings that built the ruins of Teboba and the structures still evident in places like the City of Ben Doa and the roads of coastal Fangort. No confirmation has been found of the date of this construction, but if the Teeth are contemporary with the ruins at Teboba and Ben Doa, then they would be more than 5,500 years old. A high degree of sophisticated engineering would be required to lay that many miles of road and erecting nearly 900 stones (each weighing at least 100 tons, perhaps much more) with that degree of percision and exactness.   It was the ancient people of Aria that gave the stones the name "Teeth of the North" (Dentes de Nor in the Arian tongue), and in the regions north of the line of stones, they are simply referred to as "the Teeth". For centuries, the people of Aria would not build homes or settlements within a day's ride of the Teeth, fearing curses or evil spirits.
