The sight before him literally took his breath away. It was a vast, cavernous expanse. Dark black rock dominated most of the formations, but that was just the landscape. Huddled amongst the towering stalagmites and built into vast slopes were the grey towers and parapets of a vast city whose stone shone amongst the dark rock. The vast ceiling of the cavern was covered in a subtly moving mass of luminescent plantlife and shone like multihued stars, bathing the city in soft lights. Gentle, pure streams of water flowed into cunningly crafted rivulets in the walls and natural crenelations of the rock face, delivering fresh water to all points in the city.
