Guizhong, known as the Lord of Dust and Goddess of Dust, was one of the rulers of the Guili Assembly and a close friend of Zhongli. She was a pioneering mechanical engineer who conducted extensive research into ancient machinery and created the Guizhong Ballista, a massive crossbow weapon designed to protect the people of the Mt. Tianheng area. During the Archon War, she fought alongside other Adeptis to defend the mortal world from evil gods and monsters, ultimately sacrificing her life in this conflict. Her legacy includes the Hidden Palace of Guizang Formula, a realm she created to contain dangerous artifacts discovered during her mechanical research. She is remembered through historical records and the Memory of Dust weapon, which references her conversations with Zhongli.
