Threads and themes

The long fuses, and what the series is about. The open threads page is the ledger: what each book lit, moved and closed.

Threads

• 'You're not going to break me' from book 1 — Carl's mantra, first said to a safe-room ceiling after the You Monster! achievement and repeated whenever the game succeeds in making him feel like an asshole. The line the whole series will test.
• Addiction from book 2 — Katia's four drugs, from the Desperado Club, where blitz sticks are sold openly, and its frozen-yogurt drug den Carl told her about: a painkiller, ground fairy wings, blitz sticks of false memories, and Glory Bound, a coma that relives one — stats scrambled, a rainbow into Louis's bucket, a cure that is a bad trip through her worst memory. Carl thinks of his father, and then of himself. 'I do understand. I don't want to. That's the problem.'
• Already married from book 7 — 'Oh, I wish you weren't already married,' says Eris, All Knowing; Carl has no idea. Quasar, at the end: Donut's lawyer, Princess Chandra, Esquire — 'She's your new wife.'
• Carl's family from book 1 — 'After a stint in the US Coast Guard, I ended up working as a marine tech.' What Carl says of himself in the first chapter, and what leaks out after: a mother who locked him in the basement with his father's Frogger machine whenever his father's friends came over, and who left; a heavily tattooed father who laughed at him, broke his slingshot and never replaced it, and drove on past a wrecked moving truck saying it was a shame.
• Eileithyia's boons from book 6 — Katia's celestial prize for flooding Larracos, unopened since the sixth floor: the Engaged Lock Box of the Night Wyrm, three seals, and inside it the Orchid of Eileithyia's Grace — an hour at 1% health for one of three boons: triple constitution; Celestial Attendant, frozen as an NPC on the twelfth floor; or a child and the Kinder Facility in Mumbai. Won with Astrid's death; 'I won't eat it until we get down to the ninth.'
• Lucia's voices from book 5 — Points, a bridge, a papa, a youth assistant nobody else can see — and, at the party, a ten-year-old Dutch girl named Jill who knew the prime minister, in Lucia Mar's head with other children: 'There are multiple people in there. Real people, mostly kids.' Something to do with the dog and a man named Alexandro, Florin says, and he believes the dog can still control her from afar in short bursts. 'You guys said there were no children crawlers allowed.' 'It's complicated, Carl.'
• Odette and Mordecai from book 6 — The prologue's crawl and its bill: Odette as Mordecai's manager, staring into the eye, bribing Huanxin, tricking her, and killing Uzzi to buy a key; Armita dead for it the next season; Mordecai drinking for centuries while Odette watches. 'It's about Mordecai. It always has been.' A trust set aside; a plan to die killing Huanxin. Mordecai will not say a word of it.
• Primal engines from book 5 — Rice-grain computers at the core of certain planets, older than the planets — the resistance's life rafts, 'not meant to do what you think they would do': the biological fail-safe of the Primals, a people who ended their wars by becoming a collective mind and hunted the refusers. The mantises' macro AIs, installed into the engines 'like installing a consciousness in a zygote', are cups dipped from the collective's ocean; the Earth AI is one, and so, Carl concludes, is every sapient mob — 'Primals. All of them. All the way down.'
• Samantha's body from book 4 — Princess Lunette's weightless golem in Carl's inventory, a fish tattoo made flesh, and Shi Maria's promise of a master pulpmancer in Larracos who could move Samantha in, though the mage's shop was in the city's drowned bottom levels and Carl thinks the mage most likely dead. Meanwhile the doll head's neck hole is deeper on the inside — gold coins, a badger's arm burned black, spider automatons and a teleport trap, and, for twenty seconds, Carl's head.
• Seeds from book 2 — 'All it takes is a little seed.' Carl's mother's line, remembered at the circus, becomes his long game: talking Grimaldi down instead of killing him, the frog-in-the-pot speech that gets a trailer pulsed from orbit. 'Mordecai had his plans. I had my own.'
• The collapse dead from book 4 — 'People who die in the collapse aren't really dead, but they're put in storage.' Maggie's claim, in Chris's voice, that the dead of the first night can be brought back, changed, and put in a crawler's path on the deeper floors; the Cookbook has hints of it and Mordecai has not been asked. The epilogue's word for them is the Collected.
• The count from book 4 — Carl's tally of administrators killed, begun on the fifth floor with a note in the 25th edition — 'One.' — after a toy exploded beside Loita in a shielded trailer. Written for Coolie and for a gnome girl named Bonnie; 'What I do from here on out is solely for me and my people.'
• The death of Geyrun from book 4 — Emberus's quest to find who killed his son: Hellik denies it, Vinata worships Khepri to get into his temple, the memorial crystal shows itself, and Samantha says out loud that she may have had a hand in it — because the doggie would go to the Nothing, and she does not know who the guy in the hoodie was. Sixty-six minutes.
• The Eulogist from book 6 — The Primals' collective in its final form: asleep since it thought the nine-tier attack had succeeded, guarded by a smaller instance of itself that sheds Residuals, worshipped by the Nebulars, exploited by the Syndicate as the centre system where many people live, and shrinking toward a singularity for as long as it sleeps — 'May the Eulogist ever sleep'. Every macro AI is a cup dipped from it; the Earth AI, in its broadcast, says 'I am not the Eulogist'.
• The failsafe from book 6 — The Syndicate Council's last resort for a crawl gone wrong: kill the system's star. Cascadia is 'one crisis shy' of it on the eighth floor; Zev prays they never learn what it does; Princess Formidable demands it and is muted on a decorum sanction; Prime Minister Glory refuses, because half the galaxy's wealth is trapped in orbit and in the Scolopendra Club.
• The Great Consensus from book 4 — A kua-tin ideal that Loita names over Zev's generation on the fifth floor. On the sixth, Edict, a mantis merchant of Deep Mind, says it is what the kua-tin call the understanding that finding the stars was the worst thing that ever happened to his people, and that there is in fact no agreement.
• The Inevitable Ruin from book 7 — The moment you recognise a lost cause, after which nothing you do changes the outcome — the name a sward mantis's queen used for it, and a curse on the mind of the Hunter Wraith that ruins something pure by telling the truth. Carl knows the phrase in his bones without knowing from where — 'Do you remember the circus?' — and calls it hopelessness in another form.
• The kinder facility from book 5 — Where the children and the pregnant women of Earth are kept, physically, above the dungeon: Jurgen's Heidi, the 120,000 bound to Lucia, and, at the end, Katia, who chooses pregnancy to get there. Eileithyia senses her daughters there and cannot reach them.
• The Oak Fell from book 2 — The elves' tree goddess and her antichrist. Three separate stories about angels, an oakwood anklet from a dead crawler, and a cat with an award-winning derriere become, in the minds of nine city elves, the end of days. Mordecai says this is twelfth-floor stuff.
• The Pineapple Cabaret from book 7 — A pocket dimension built by two former crawlers, Herot and Menerva, behind the seventeenth floor as an oasis for awakened NPCs — outside the playing field, so a crawler inside at collapse is 'lost', not killed — now infested with the Ogre Imperium, shadow mimics and 'things that Agatha can and will wake'. No god-worshipper may enter. Two hundred and twenty-eight crawlers go by cleaner bot; the casino's holding-area door sends the rest to Sheol instead.
• The river in Carl's head from book 5 — A stream that has always murmured, louder in heat and muted only by rest, which the sixth floor names: 'The water is running.' It roars at the Grand Canyon in memory, at Bea's hologram, at the name Ferdinand, when Gideon's team dies because Carl asked. 'The sink is running. We're not supposed to let it run.'
• The Sluggalos from book 6 — Doctor Bones's Conscript charm on the slugs bred from Super-Spread strippers locked in a room for a day: forty hatchet-swinging idiots in orange slime who Leeroy a block of demons and retreat through Donut. 'If we get a few thousand more of these guys, we could win the war on the first day.' 'Don't forget how Carl makes these.'
• Waking the NPCs from book 2 — What the dungeon's people know about themselves: Mordecai's distinction between naturals, whose memories cannot be altered unless they sign away their rights, and the printed and imprinted rest, and the question, whenever an NPC seems to know more than it should, of what waking would mean.
• Ysalte from book 6 — Goddess of Hopelessness and Insanity, level 250, once of the Dirt, then of Tears; the Semeru dwarves' only goddess, patron of outcasts and bards, half-sister and niece of her former lover Taranis, threatened with the Nothing by Apito and fled to Sheol; Amayon's ex and mother of his child. Sponsored by Pontifex Shine of the Nebular Balance and not driven, she arrives through Sister Ines's corpse as a young dwarf with a pickaxe and a flickering scream, turns every potion to vinegar, enslaves a Demon Prince — and is beheaded by her own totem. A memorial crystal waits on a future floor.

Themes

• Entertainment as machinery — Everyone Carl meets is a part of the same inexorable machine — Zev's phrase — from the AI that tailors loot to the narrative, to the PR agent who asks him to repeat a line without coughing, to the prince who buys doomed crawlers for a game show. The game is cruel because cruelty is what tunnels.
• Staying human — 'If we get to the point where we don't help each other anymore, that's when we stop being human.' The book's argument with itself: Carl covers the Meadow Lark signs so no one farms the elderly for experience, is told by twenty percent of a focus group that he is carrying dead weight, and cannot decide whether keeping them alive was a kindness.
• The mobs are victims — The Hoarder begs in Spanish to be sent to Jesus; the Juicer is proud of Carl for fighting through the pain; the tuskling courtesans seem to have no memory of the ball; the goblin shamanka wants only to breed in peace deeper down. Mordecai warns it will not always be so, and that there are no gods here — only those who pay for the privilege.
