Nightmare Fuel / The Bartimaeus Trilogy

• Honorious slaughtering the entire Resistance as Kitty is desperately trying to escape.
• In the third book when all the members of Makepeace's conspiracy have been taken over by the demons they summoned and all start laughing in a completely emotionless way.
• The best description for the death of Verroq, found right in the book itself: "Bones in black clothes."
• The description of just what exactly is in Khaba's vaults. Mummies, multiple skeletons (of both animals and humans), tortured spirits...
• Gezeri's final attack on Asmira - he's mentioned as having lots of sharp teeth and claws, as well as skittering with "horrible speed" like some sort of demonic spider.
• The most powerful spirits are enslaved for thousands of years and if lucky get only a few years in-between periods of captivity. Imagine being cursed with a potent combination of raw physical strength, cunning and intelligence and being forced to serve as a slave for thousands of years.
• In general, the spirits all declare I'm a Humanitarian. They will eat people every chance they get, as well as each other. What happens after one is eaten by a spirit in material guise is left to the reader, but the screams aren't very encouraging. In a rare moment of real darkness, Bartimaeus shows exactly what happens to magicians who screw up:
  Ezekiel: [having been blown out of his protective circle] Bartimaeus—
  Bartimaeus: '[showing More Teeth than the Osmond Family] That's my name. Now... Are you going to get up, or shall I come to you?
  The answer he made was incoherent. The pretty maiden shrugged. Then she bared her pretty teeth and fell upon him, and any further sounds he made were swiftly stilled.
