Nightmare Fuel / Kushiel's Legacy
- Melisande drugging Phedre and Joscelin, torturing Phedre for information and selling them both to the Skaldi.
- Phedre is almost raped by two Skaldi in Selig's steading while on her way to farewell Gunther's people.
- The brutal murders of Fortun and Remy.
- Pretty much everything the Mahrkagir does qualifies.
- The portion of Avatar set in Darsanga when it's not being Fetish Fuel.
- Of course, as Phèdre points out, it's possible for something to be both horrific and Fetish Fuel at once.
