Compose a short description of a spooky scene inside a cave cavern with an arching roof and a smooth floor.
assistant
The floor of this bell-shaped room is smooth and level and so free of debris that it warrants suspicion. An arching roof of smooth rock flies up overhead, fading off into the cave's natural darkness. A pale greenish light from the north fills the cavern partially, becoming gradually watered down and consumed as it tries to reach south.
