Write a detailed description of a enchanting scene inside a tunnel cavern with crystals.
assistant
The tunnel doglegs, turning back on itself around a sharp protuberance of crystalline glaes. The dark crystals jut from their sparkling bed of crusted mineral like a multifaceted forest. Each one is different, and the largest are particularly beautiful. They reach out from the wall halfway across the corridor, and if time had given them a chance to grow longer, they would effectively block the passageway.
