Human: Produce a detailed written description of a spooky scene outside a forest with a wall and a line. Assistant: 
Lush vegetation fills most of the area and green forests and plains are easily visible to the east. A blackened line is carved into the ground, everything west of it dead or withering, forming a stark contrast as verdant green stands opposed to dull grey and brown. Shortly past the dead zone, an oily wall of black energy rises from the ground, stretching as far as the eye can see. Streaks of ominous red power crackle across it constantly, its makeup just opaque enough to bar any ability to see beyond.
