Describe a spooky scene outside of a medieval keep with gnats and an iron portcullis.
assistant
An iron portcullis blocks a dark tunnel leading deep within the walls. Howls and screeches drift across the sands from the doorway, mingling with the sounds of the spectators. Swarms of gnats fly thick in the air like angry black clouds, occasionally darting to the walls to feast on the blood of the recently dead.
