Nightmare Fuel / Doctrine of Labyrinths

• Felix's Keeper, a man who inflicted horrific emotional, psychological, physical, and sexual abuse on his kept-thieves. Even after he has been dead for years Felix is still deathly afraid of him.
• Felix talking about his past as a child prostitute. Doubles as a Tear Jerker.
• Almost any scene with Malkar.
• The scene in the Boneprince when Vey Coruscant tries to raise Brinvillier Strych and the something that replies.
• Felix's time in St. Crellifer's.
• Mildmay's nightmare of having sex with Kolkhis, who turns into a dead Ginevra mid-way through.
• Both times Felix is arrested and has to sit in a pitch-black cell, waiting to find out if he'll be burned alive.
• Whatever happened to Mildmay while he was a prisoner of Malkar. Made worse because we're never given the details.
• The fantôme, in both Melusine and Corambis.
• The orgy to restart the Titan Clock in Corambis.
• Mildmay waking up in Corambis to Felix, soaking wet from trying to drown himself, calmly telling Mildmay to drown him to save him from the fantôme that's trying to possess him.
