The three children grew up together in Mangcheng, a city of freedom and light guarded by a mysterious organization called the Silver Hand. The three children once met a mysterious businessman in the monster market, and were inadvertently involved in a struggle between various forces. They continued to take risks in sadness and miracles, and learned a huge secret about the elves, necromancers, holy mages, dwarves, wooden men and mermaids. That is that an angel fell from the sky thousands of years ago, his body was torn apart in the world, and his soul fell into the abyss. The three children destroyed the Necromancer's conspiracy through an encounter, but eventually had to part ways.
