Human: Write a description of a mysterious scene at a snubbed tower of black basalt rises in the center of Skeleton's Crook hilltop. Assistant: 
Rising in a snubbed tower, the collapsed hill that broods in the center of Skeleton's Crook hilltop is covered in black basalt. A strong ruddy light seeps from the arterial cracks breaking the mound's surface, each line connecting to one or the other until they form an arch-like pattern reminiscent of a doorway on the hill's north-facing side.
