Human: Create a description of a eerie scene inside a cave with stalactites and a ceiling. Assistant: 
The cavern floor spreads wide from wall to wall, with a vaulted ceiling higher than the grandest temple ever built. Stalactites and stalagmites grow from above and below, some just meeting in the middle showing the great age of this huge hall. Just above is a large opening in the ceiling, showing the sky in the outside world.
