Spoilers Off applies to all Nightmare Fuel pages, so here be unmarked spoilers. You Have Been Warned!
Neither Harry Potter nor The Owl House are strangers to Nightmare Fuel, so this page existing shouldn't come as a surprise.
- When the gang encounter Gregore again, Eda is incapacitated, and it's clear that if he hadn't wanted to look his best when defeating her, they would have been goners. And then once he and his goons are defeated, the Ashbelly that they were containing escapes because no one was reinforcing the ice spells on the fire snake's cage, and only Harry's quick intervention with Parseltongue stops it from burning half the city down.
- The fate of Benjy Fenwick is quite horrific and described in equally horrific detail, Dolohov's curse slowly melting off his face and eventually leaving nothing but a bare, blood-covered skull.
- Faust's funeral turns out to be a plot for revenge on the troublemakers at his school and his brother, as he has a band play a forbidden Bard spell called the Grey Dirge to drain their minds, and it's only stopped because Harry inherited Lilith's allergies to Faust's favorite flower, so he, Eda, and Raine were outside the building when they started.
- The maze on Monster Island turns out to be filled with Dementors, or "Wraiths" as the Boiling Isles know them as, trapped there for centuries. Pretty much every scene involving them and everything about them is terrifying. Beyond the mental effects they have on all characters, the Boiling Isles witches appear to have no feasible way of fighting them. Neither Eda's or Darius' magic is capable of harming them, meaning the Dementors are pretty much invincible. It's clear that, had it not been for the Patronus guardians of the maze, the Dementors would have easily overtaken them and escaped.
- Building on the point above, the unfortunate coven scouts who first found the maze ended up trapped in it, and Word Of God has it they all ended up getting the Dementor's Kiss. The description of the Kissed scout Luz finds is nothing short of horrifying. A bit of Fridge Horror in thinking about how the poor scouts' last days must have been like, trapped in a dark, seemingly endless maze with evil creatures none of them could even fight.
- The way the nature of Harry's scar, or rather the Horcrux, is described when Lilith perceives it by use of the Sight is unnerving to say the least. It is "perfect, absolute nothingness", an absence of feeling or humanity. Whereas everyone and every thing can be perceived as a song and what that song represents, Lilith instead perceives the scar as a shivering, unending scream. It really hammers in the fact that splitting a soul is something unnatural and wrong.
- Vitimir. Just... Just Vitimir. Where to begin?
- He is revealed to have a habit of abducting rare magical creatures and vivisecting them alive, and is implied to do the same to witches as well.
- The whole description of the flayed chimaera. How it's exposed muscles twitch, how one could hear weak breaths from its two heads, how the skin lay empty and discarded on the floor... It's sickening imagery.
- Vitimir is described by Lilith as "more poison than witch". When he's bitten by countless venomous snakes, they die instead of him. He doesn't bleed either, instead leaking some smoking, yellow pus. It makes you wonder just what the hell kind of experiments he has been doing to himself.
- The whole description of the effects of his "Burning Breath", how it feels as if knives are cutting the insides of your throat, how your lungs are being shredded from the inside. It's made all the more horrific by the fact that the one describing and experiencing all of this is Harry, an eleven-year old boy.
- There's also something incredibly disturbing about the fact that Lilith's problem with these experiments (with the exception of his interest in Harry) isn't how deplorable or needlessly cruel they are, but rather that Vitimir performs them without Belos' permission. Really think about that means for how the Isles are governed or the moral limits of Belos .
- When listing Vitimir's other side-projects, Hunter also mentions "strange reports from the Femur County Morgue" and an "epidemic in Wristberg". Messing with dead bodies and potentially starting some sort of virus? It all feels very sinister, especially consider we aren't given any further details.
- Even even half of what is said about the Witch King is true, he was a seriously nasty character that caused much pain to the Isles before Belos defeated him.
- Belos reveals that he knew about Lilith's pregnancy all along, and kept sending her on dangerous missions anyway as a Secret Test of Character to see if she would put fanatical loyalty to him before her maternal instincts.
- When forced to admit that Harry is the baby she gave up, Lilith is so desperate not to be ordered to cut contact with him in the present that she's forced to tell Belos about how he somehow survived the Killing Curse, spinning it as trying to find a way to make him useful to the Emperor. Which unfortunately works, as Belos is now clearly interested in Harry, which has very serious implications going forward.
- The Witch-King's Knights, after his defeat, were mummified alive, and died slowly in the dark catacombs of Kneetop.
- Kneetop itself qualifies. After fifty years of being haunted, the place has become "a bit of a ghost itself" as Amity puts it. The city gives off a feeling of deep unease simply by looking at it, and walking inside of it is even worse. With descriptions of whispers, chillingly wrong dimensions, and nausea, it reads like a mix of Minas Morgul and R'lyeh.
