Human: Generate for me a description of a eerie scene outside town ruins with an obsidian tail. Assistant: 
A cloak of dusky darkness shrouds a giant, segmented obsidian tail that arcs out of the foliage behind the southern structure, curving upward to a tall spire far up in the inky midnight sky. The tail appears remarkably similar to a creature that is more insect in nature, rather than the mammalian jackal depicted in the rest of the ancient stone.
