TYLD lore
These characters are mentioned in the main project's story "Then Your Love Dies".
Hatori Longshadow's and Kaj Llingvam's family; mostly mentioned in TYLD lore, but actualy is the main family of whole project.
The world of these characters pictured as just a "land" where were once immortal ppl and higher gods, but then gods became bored and set mortality and two minor goddesses to deal with it. They're quite a bit opposites: cruel and selfish one who answers for souls, Shiqu, and light-hearted and upbeat one, who answers for all the rest, Shenming. They both have assistants, but if You is more like a soldier or even a slave of Shiqu, Xu usually feels sorry for him.
These characters were mentioned in old story/roleplay named "Picture gallery".
