Before them stood Cytherea the First, though they noticed her only as an afterthought. She stood with her sword down, just watching them, her eyes as wide and as blue as the death of light. The garden narrowed to her and her bloody green sword. Her lips were parted in a tiny o. She did not even seem particularly troubled: just amazed, as though they were an aurora, a mirage, an unreal trick of the sunshine.
“Now we kick her ass until candy comes out,” said Gideon. “Oh, damn, Nonagesimus, don’t cry, we can’t fight her if you’re crying.”
Harrow said, with some difficulty: “I cannot conceive of a universe without you in it.”
“Yes you can, it’s just less great and less hot,” said Gideon.
“Fuck you, Nav—”
“Harrowhark,” said Gideon the Ninth. “Someday you’ll die and get buried in the ground, and we can work this out then. For now—I can’t say you’ll be fine. I can’t say we did the right thing. I can’t tell you shit. I’m basically a hallucination produced by your brain chemistry while coping with the massive trauma of splicing in my brain chemistry. Even if I wasn’t, I don’t know jack, Harrow, I never did—except for one thing.”
She lifted Harrow’s arm with the hilt clutched in it. Her fingers, rough and strong and sure, moved Harrow’s other hand into place above the pommel.
“I know the sword,” she said. “And now, so do you.”
Gideon brought them into position: weight on the forward foot, knee bent a little, light on the right. She tilted the blade so that it was held with the blade pointed high before them, a perfect line. She moved Harrow’s head up and corrected her hips.
Time sped up, blurred, moved in bright lights before them. Now the old Lyctor Cytherea—wretchedly old, it seemed impossible that they could have ever taken her for anything else—stood there at the bottom of the stairs. Her radioactive blue eyes were quiet; her sword was held at the ready. She was smiling with colourless lips.
“How do you feel, little sister?” she said.
Harrowhark’s mouth said, “Ready for round three,” and, “or round four, I think I lost track.”
Their swords met. The noise of metal on metal screamed in that empty garden. Cytherea the First had been Cytherea the First for ten thousand years, and even ten thousand years ago her cavalier had been great. Time had made her more perfect than a mortal cavalier could understand. In a fair fight, they might even have fought to a standstill.
It was not a fair fight. As they fought—and fighting was like a dream, like falling asleep—they could see Cytherea was made up of different parts. Her eyes had been taken from somewhere else, two blue spots of someone else’s fire. Within her chest another conflagration burned, and this one was eating her alive: it smoked and smouldered where her lungs ought to have been, bulging, dark, and malignant. It had swollen to the bursting point inside her body, and most of Cytherea’s energy was being expended on holding it still. Harrow could touch what Palamedes had done; nudge it; knock it out of Cytherea’s grip.
“There,” said Gideon, in Harrow’s ear, her voice softer now. “Thanks, Palamedes.”
“Sextus was a marvel,” admitted Harrow.
“Too bad you didn’t marry him. You’re both into old dead chicks.”
“Gideon—”
“Focus, Nonagesimus. You know what to do.”
Cytherea the First vomited a long stream of black blood. There was no fear in her now. There was only anticipation verging on panicked excitement, like a girl waiting for her birthday party. The weight of Gideon’s arms on Harrow’s forearms was getting more ephemeral, harder to perceive; the brush of Gideon’s cheek was suddenly no more substantial than the remembrance of an old fever. Her voice was in her ear, but it was very far away.
Harrow placed the tip of her sword to the right of Cytherea’s breastbone. The world was slow and chilly.
“One flesh, one end,” said Gideon, and it was a murmur now, on the very edge of hearing.
Harrow said, “Don’t leave me.”
“The land that shall receive thee dying, in the same will I die: and there will I be buried. The Lord do so and so to me, and add more also, if aught but death part me and thee,” said Gideon. “See you on the flip side, sugarlips.”

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.
