Hollow Mountains

These low mountains have long been the center of tales about tunnels, which descend into caverns large enough to house entire cities, and networks of natural tunnels, which suddenly give way to worked stone or are blocked by stone walls of intelligent manufacture. It is certainly true the area is riddled with caves and tunnels, but avalanches and cave-ins are frequent, and most folk choose to avoid the higher slopes where the caves are said to exist.
