Human: Please generate a detailed description of a spooky scene in a field with a grassy mound and crackling in the air. Assistant: 
The crumbled stones that mark the edges of the old road end at the foot of a large, grassy mound that rises from the field just to the east. The air is still here, shielded from the wind by the unnaturally symmetrical hill, and a strange crackling like nearby lightning shimmers in the air.
