Corulag: Dunelands - Bone Road Out of the gravel plain to the southeast, the hills slowly rise up and each hill is higher than the one before. The terrain, dull red rock and loose gravel and soil, is more than a match for even the heartiest of wayfarers. Just when it looks like going farther will be impossible, a wide road forms on an artificially flat stretch of land, as if the hills themselves have been flattened. The land is at least a kilometer across and along its length is a road paved with stones and demarcated by large bone curved bones that jut up into the sky, each five meters in height.
