There are many perils in this desert world. Countries war and enslave, goblins prey on humans, monsters and magic run amok, and - most critically - wells run dry. Those desperate for water may undertake an ancient water prayer ritual, a grueling journey to beg the aid of Kahaku, the god of water. These are the various stories of people from all walks of life, each driven by their need to survive in that world and save the ones they love. Sometimes, these desperate souls cross paths with a pair of travelers, En and Linghua, who help them on their journey.
