Zeng flapped lightly down in front of the cave mouth. The Dragon Grotto lay through the tunnel ahead of him, candles lined along the floor casting orange firelight and dancing shadows across the walls. Zeng took a few more reluctant steps forward, feeling as though he were intruding on sacred ground, like he had crossed into a space that wasn’t meant for him. Continuing into the firelit tunnel, the only sound was the slap of his feet against the cold stone floor, the echoes trailing off into the vast stillness.

Zeng entered a large chamber, where a crystal-clear pool filled most of the space, fed by a tall waterfall cascading down a steep cliff at the back. Mist rose from the waterfall, drifting over the chamber and softening the fading light of the setting sun, which struggled to break through the distant mountains. The cool, damp air was alive with the sound of rushing water, filling the vast cavern. In the center of the chamber, an enormous dragon statue, coiled and covered in moss, loomed over the pool, its presence as imposing as it was ancient.
