Human: Write a detailed description of a spooky cave in the wilderness with quartz crystals and phosphorescent fungi. Assistant: 
A high plaster wall marks the end of Diamond Street, the road narrowing down until it splits into three parts. One leads up to a sweeping marble archway, while the other two paths circumvent the barrier. The night reflects off the tower's polished surface, blurring its outline until it seems to melt into the stars.
