History NightmareFuel / TheLaundryFiles

** The 'Ward of Nightmares' in the GPM compound too; not only are the women there permanently and completely paralysed, but they're forced to constantly produce children for the Ministry, unwittingly contributing to the end of the world.

* A bit of ParanoiaFuel combined with FridgeHorror. The Sleeper in the Pyramid seems terrifyingly adept at insinuating itself into belief systems. He manipulated Schiller and the Golden Promise Ministries into thinking he's Jesus so they'd stop at nothing to resurrect their Lord. But ''Delirium Brief'' also tells us that all this talk of the hierarchy of horrors was a lie as well. One does NOT need to wake the Sleeper to summon Nyarlathotep. In fact, the two despise each other. But the Sleeper managed to make even the Cult of the Black Pharaoh believe they needed to summon him instead of their actual master. Which begs the question: How many agencies and cults has he misled into inadvertantly helping him wake up?

** [[spoiler:And those same people run the country by ''Labyrinth Index''. Happy Joy!]]

** It gets worse. In ''The Rhesus Chart'', [[spoiler:it turns out that it's a second-order vampire, wide awake and hungry, capable of partially controlling the actions of Agent CANDID, and it's now ''extremely pissed off'' at Agent HOWARD.]]
*** It gets ''WORSE''. It's a fragment of [[spoiler: an elder god, specifically the King in Yellow and using it to play certain pieces of music can summon the King fully from Lost Carcosa. And while Mo's might be neutralised, it wasn't the only one and some of them are unaccounted for.]]

** And then, in ''Delirium Brief'' it gets worse as it introduces the hypercastrating variant referenced back in ''Codex''. These look like segmented lamprey eels that dig into the host's nether regions instead. Worse, the people hosting these parasites are NOT brainwashed. They are very much aware and part of a HiveMind that functions terrifyingly well. It's a good thing ''Delirium Brief'' ended the way it did or [[spoiler:Schiller's Assistant Anneka might have become an even bigger threat than him in the long run since she had all of his devotion with none of his scruples.]]

* If you thought the Sleeper's parasites were bad, you definitely don't want to hear about [[spoiler:Dread Cthulhu's.]] [[spoiler:Dread Cthulhu]], being hypothesized to be a hivemind of insectile creatures, communicates with its followers through its mouthpieces. Basically human-sized parasitic wasps that lay their eggs in humans. One of the larvae will eat its way to the human's brainstem, absorb their personality and then take over their body. The deterioration of the body is twofold here. On the one hand the body begins rotting and melting as the larva slowly grows into an adult wasp and on the other hand, the larva actively consumes the host's body, as we see the mouthpiece casually chowing down on one of its host body's fingers and seven of them already being gone. By the end the rest of the human body simply sloughs off the wasp, at which point the wasp will sting a new human to act as the next mouthpiece.

** And let's not forget Cassie's bombshell late into ''Delirium Brief'': [[spoiler:The Sleeper was the one who destroyed her home world.]] Pretty impressive for a being that's supposedly almost dead and incapable of acting.

* ''Equoid'' manages to make unicorns ''horrifying''. [[spoiler: Ia Shub-Niggurath ia!]]

* [[AC:Scorpion Stare]], in ''The Nightmare Stacks', has GoneHorriblyWrong. [[spoiler:Faced with a faerie invasion force heading to the heart of Leeds, and with the British Army reinforcements still on the way, the Laundry decides to activate the local [[AC:Maginot Blue Stars]] CCTV network to slow them down. The network is fitted with an image-recognition algorithm that should, in theory, zap many-angled invaders into ashes while minimising accidental human casualties. Only it proves utterly useless against the heavily-warded invading army, and what's worse, fails to account for several hundred costumed anime convention-goers accidentally trespassing the zone of exclusion...]]

* The sheer level of PersonOfMassDestruction that Bob operates on in ''Delirium Brief''. Before [[spoiler:he gained Angleton's powers]] he was terrified of fights for fear of getting hurt. Now he's scared of fights for fear of accidentally killing everyone in a ten mile radius. And for good reason...
* In ''The Delirium Brief'', the Senior Auditor's gambit to save the British Isles from [[spoiler:the Sleeper in the Pyramid - freeing Fabian Everyman, aka the Mandate, AKA the Living Avatar of the Black Pharaoh itself from prison and effectively handing over control of the entire United Kingdom to him.]]
* The Black Chamber's plan deserves a mention, for its sheer audacity. They plan to awaken their master, [[spoiler:Dread Cthulhu]]. Doing so will need a super computer. How super? They're co-opting the entirety of the US government, as well as Apple and dozens of other companies in order to hollow out all planets of our solar system, turn them all into [[DysonSphere Dyson Spheres]] to house said computer and eventually want to even hollow out the Earth. Although BLUE HADES and DEEP SEVEN may have some issues with that last part. And this solar system-spanning computer, along with roughly a hundred million human sacrifices, should suffice. And they want to be done with this plan in three years.

** The world may soon find out; according to WordOfGod, ''The Nightmare Stacks'' is about what happens when the Laundry gets blindsided by CASE NIGHTMARE RED...
