The Chariot and the God

Publisher's blurb:

The waters of the Three Sticks Lake descend into depths unknown, serving as a limitless source of water for travelers in the Ultraviolet Grasslands. Caravans take treacherous trips across the Glass Bridge to resupply here. A few weeks ago, a violently colorful streak plummeted through the sky, tearing a swath through the land and upsetting the waters of the lake. Since then, the waters have become poisonous, and the villagers have seen a great shadow moving within... The villagers speak of a mournful song carried on the wind. They say that the god sleeping in the mountain beneath the earth has been awakened, and he will have his reckoning. None dare approach the waters...
