Write a detailed description of a spooky scene outside a mountain canyon with a fossilized wyvern skeleton.
assistant
The walls of the mountain canyon narrow considerably to the north, making the mountain peaks seem incredibly tall in comparison. A huge and ancient wyvern skeleton is fossilized and half sunk into one of the cliff walls, its neck bent sharply backwards as if it died while in a great struggle. Much larger than any of the creatures that currently cover the mountain, the bones speak of an ancient and mysterious past.
