YMMV / Foxfire (Rahar_Moonfire)

• Complete Monster: Hongqi, son of Quon, was the son of a fabulously wealthy merchant and never had to work for anything outside of his earthbending. He takes a Lower Ring woman as a mistress and starts a family with her in secret, but gets bored of his mistress and wants to marry a richer woman. Despite dumping the poor woman, Hongqi didn't want her to move from him, so he disfigures her by giving her a Glasgow Grin and destroys her emotionally by taking away her children, preventing her from seeing them, and dumps her back in the Lower Ring; the mistress commits suicide. After a while, Hongqi grew bored of his children and finally found a wealthy young bride to marry. Not wanting his future in-laws to find out about his bastard children, Hongqi murders his own toddler-aged children by trapping them in an active kiln and shutting it closed with earthbending, cremating the children alive.
• Cry for the Devil: While Kuchisake-Onna has a big body count, her past is very tragic and she's finally able to rest in peace when Li reunites her with the spirits of the children.
• Moral Event Horizon: Killing your own children by locking them alive in a pottery kiln.
• Squick:
  • The cholera epidemic in the Lower Ring. Diarrhea and vomiting are such charming things...
  • Then the origin of the disease is revealed: a woman (the Kuchisake-Onna) threw herself down a well, which means people fell sick from drinking water polluted by her rotting corpse.
