Geographically, this mountain range is one of the steepest ranges in Feila, and extends from coast to coast. It is mostly composed of a dark igneous rock that gives it its distinct hue for which it is named. It is possible to cross the range by a few serviceable paths, of which may be hazardous, and require special equipment, unless one can fly. In the gullies of the range there is substantial forest, which is home to varied wild species of animal, and if you're unlucky several wild species of anthropomorphic animals. Such an example of which is two large dragons known to live in the area.
