Baigujing demons are skeletal creatures that typically reside in Diyu. They are often called Baigujing's daughters, referring to the Greater Demon that is considered their mother and whom they were named after.
Description[]
The Baigujing demons resemble their Greater Demon mother's real form which is described as simply being a skeleton.
History[]
In the 18th and 19th centuries, when Yanluo was terrorizing China, their mother banded with him, and they joined the army of demons, wreaking havoc across the country. When Yanluo was defeating in 1875, the Baigujings were trapped in his realm of Diyu with their mother.
Over a century passed without a single Baigujing demon being spotted until 2010. Their realm had been taken over by Sammael and his warlock minions began opening Portals all across Shanghai for them to come through. As Portals everywhere began malfunctioning, they were able to slip through to other places as well.
Eventually Alec Lightwood, Magnus Bane, and their friends traveled to Diyu and shut the Portal to their world. Diyu soon began crumbling once Shinyun Jung became a Greater Demon herself and decided to destroy the realm. The Baigujing demons are now, presumably, extinct.[1]
