The underground river in the darkness was far from safe.

Before long, she saw firelight flickering on the water's surface. She concealed the red glow in her eyes and quietly approached, hiding in the darkness beneath the surface.
This was where the miners and cultivators inside the sinkhole lived and collected water. Wooden buckets were lowered into the water, filled, and hauled away. Torches illuminated the cave, while many slaves busied themselves cooking and boiling water.
