Core theme: The story follows generations of the Guardian Lineage as they search for the Devourers of Summer, a people skilled in bronze casting, infiltration, and human sacrifice. They call their true form the Devourer Clan, and the various peoples they attach themselves to their shells. The search connects hidden threads of Chinese history from Erlitou through the Song and Yuan dynasties, revealing how the Devourer Clan expanded by using bronze casting and iron smelting as the foundation of its productive power, and human sacrifice and infiltration as tools of control. At its heart, the story explores the idea that ethnic identity is not determined by genes: cultural inheritance is the root of Chinese civilization.
