You were afraid someone might take your sword away from you if you left it; rather than lifting it, you lay down next to where it glowered at you blackly from the bed. You rolled over onto its flat steel breadth and bound crisscross straps of dense bone across your back, around the blade, around the hilt. Straining beneath its weight, with nothing but a ripped-up sheet to mask you, pathetic in your turquoise nudity, you found yourself accompanying the Emperor down long black corridors, trying to fix yourself in time and space.

Harrow the Ninth - Act One, Chapter Two

“I see you calling my bluff and I resent it,” said Gideon. “So, hey. What do you really use when you’re not pretending the rapier’s your main wield? Two short blades of equal length, or one blade and one baton?”
Her keen eyes narrowed into black-lined slits. “How did I mess up?” she asked, eventually.
“You drew your rapier and your dagger at the same time. And you’re ambidextrous. You keep cutting like both your blades are curved. Also, there’s six swords and a nightstick on your bed.”
“Should’ve tidied my mess,” admitted Camilla. “Two blades. Double-edged.”

“Hardly insurmountable,” said Harrow, having regained her composure.
“Very hopeful! What would you use?”
“A corporeal ward; skin-bound, tight focus.”
“Try it.”
Harrowhark flexed her fingers slowly. Gideon watched as she narrowed her eyes into obsidian slits, fringed thickly with blunt black lashes, and then extended her hand beyond the line again. There was a brief shower of blue sparks; Harrow snatched her hand back, amazed and furious. The fingers had withered into puckered twigs; her little nail had fallen off entirely. The edges of her sleeve had holed and frayed as though assaulted by moths. Gideon lunged out of a sheer desire to do something, but Harrow held her back with her healthy hand, staring fixedly at the hurt one as it slowly mended.

Gideon moved. She heard Harrow shout a warning, but she couldn’t help it. She drew her rapier from its scabbard, and she threw herself at the grey thing wearing a person skin. It was not a cavalier: it did not meet the arc of her sword with a parry. It just clouted her with Colum’s shield with a strength no human being ever had. Gideon staggered, very nearly fell, ducked out of the way of a sword gracelessly slammed downward. She took advantage of his movement, got up close, pinned his arm between her body and her sword and shattered his wrist with a meaty crack. The thing opened its mouth and opened its eyes, right up in her face. Its eyeballs were gone—Colum’s eyeballs were gone—and now the sockets were mouths ringed with teeth, with little tongues slithering out of them. The tongue in his original mouth extended out, down, wrapping itself around her neck—

Gideon the Ninth - Act Four, Chapter Thirty-Four

Harrow still didn’t turn round, but Gideon knew innately that her eyes were rolling. “The Second House study contained a full and perfect explanation of the theorem which had been used to articulate the construct. Having studied that theorem, any halfway competent necromancer would be able to reproduce its effects. I now possess the competencies required to ride another living soul. I’m perhaps even more interested in what I’ve learned from the theorem behind the construct.”
“Making big shitty bone hunks.” Gideon preferred not to think about riding another living soul.
At that, Harrow had stopped—almost at the head of the staircase—and finally looked around. “Nav,” she’d said. “I could already make bone hunks. But now I can make them regenerate.”
The outcome literally nobody wanted.

The Reverend Daughter gave this consideration, for once. “All right. Let me—hmm. You know that a bone construct is animated by a necromantic theorem.”
“No way! I assumed you just thought super hard about bones until they happened.”
Ignoring this, Harrow continued: “This particular construct is animated by multiple theorems, all—woven together, in a sense. That enables it to do things normal constructs can’t possibly.”
“Like regenerate.”
“Yes. The way to destroy it is to unpick that tapestry, Nav, to pull on each thread in turn—in order—until the web gives way. Which would take me ten seconds, if I only had it at arm’s length.”

“It’s a bad idea, but it’s a chance, you know,” said Aiglamene abruptly. “Take it or leave it.”
“I thought you said it was the best idea we have.”
“It is—for Lady Harrowhark. You’re the best swordsman that the Ninth House has produced—maybe ever. Can’t say. I never saw Nonius fight.”

Gideon the Ninth - Act One, Chapter Four

Harrowhark drove the blade home, straight through the malignant thing in Cytherea’s chest: it bubbled and clawed out of her, a well of tumours, a cancer, and she seized up. It ran through her like a flame touched to oil, seething visibly beneath her skin, her veins, her bones. They bulged and buckled. Her skin tore; her heart strained, stretched, and, after ten thousand years’ poor service, gave out.
Cytherea the First sighed in no little relief. Then she toppled over, and she died.

Gideon the Ninth - Act Five, Chapter Thirty-Seven

“Look, this conversation is all I’ve ever dreamed about,” said Gideon, “but I’m fine. H— My necromancer overreacted.” (This, at least, seemed to strike a chord with Camilla, whose glance softened with the understanding of someone whose necromancer was also prone to gross overreaction.) “I’m just hungry. Do I or do I not seem totally fine to you?”
“You do,” said Camilla, who had pulled a frankly upsetting bulbous glass object out of her bag. “That’s what I’m worried about. Warden said you’d be in a coma. Put this in.”
The bulb, thankfully, went in the mouth. Another one tucked up into her armpit. Gideon submitted to this treatment because she had gone a round with Camilla the Sixth before and had a healthy fear of her. The other cavalier looked at her toes and fingertips, and inside her ears. Whatever she found—plus her pulse, which the other cavalier took carefully—was noted down in a fat notebook with a stub of lead pencil. These numbers were scanned with due diligence, and then Camilla shook her head.
“You’re fine,” she said. “Shouldn’t be. But you’re fine.”
