Harrow had not noticed her knocking, or her passage in; this wasn’t the problem. The problem was that the sister’s ashen paint was decorating the lovely dead face of the Body.

Her palms felt wet. In this scenario, either the sister was real and her face was not, or the sister was herself unreal. One couldn’t simply gauge all the osseous mass in the room and do a best guess; bones in meat generated so much deceptive soft thalergy, only a fool would try. She flicked her eyes over to Ortus in the faint hope that he would betray her reality one way or another. But his gaze was still levelled at the ground.

“Our House has received good service from ‘those who are fit but to hold their blade in the scabbard,’” said Harrowhark, keeping her voice even. “Which is not a line that scans, just so you know. Nobody will be surprised to find you a laggard.”

“It’s enneameter. The traditional form. Those who are fit but to hold their blade in the scabbard—”

“That’s not nine feet of anything.”

“—never to draw it forth for the battle.”

“You will train with Captain Aiglamene for the next twelve weeks,” said Harrowhark, rubbing her fingers back and forth, back and forth, until the pad of her thumb felt very hot. “You will meet the very minimum that is expected of a Ninth House cavalier primary, which is now, fortunately, that you be as broad as you are tall with arms that can carry a weight. But I need … significantly more from you … than the edge of a sword, Nigenad.”

The serving sister shadowed the edge of Harrow’s peripheral vision. Ortus had raised his head and did not acknowledge the sister, which complicated things. He looked at Harrow with the faint kind of pity she always suspected he held her in: the pity that marked him as an outsider in his own House, and would mark him as all the more an outsider in the House of his mother’s line. She did not know what made Ortus Ortus. He was a mystery too boring to solve.

“What more is there?” he asked, a little bitterly.

Harrowhark closed her eyes, which shut out Ortus’s tremulous, worried face and the shadow of the Body-faced serving girl that fell over the desk. The shadow told her nothing. Physical evidence was often a trap. She shut out the new and rusty rapier that now creaked in the scabbard at Ortus’s hip. She shut out the comforting smell of dust made hot by the whirring heater in the corner of the room, mixing with the just-milled ink in her inkwell. Tannic acid, human salts.

“This isn’t how it happens,” said the Body.

Which gave Harrow a curious strength.

“I need you to hide my infirmity,” said Harrowhark. “You see, I am insane.”

NINE MONTHS BEFORE THE EMPEROR’S MURDER

IT WAS IN THE CLOSE of the myriadic year of our Lord—that far-off King of Necromancers, that blessed Resurrector of Saints!—that you picked up your sword. This was your first big mistake.

The sword hated you to touch it. The long hilt burnt your bare hands as though heated to starlike temperatures. The vacuum of space outside yielded no thanergy and generated no thalergy, but it didn’t matter. You no longer needed either. You iced your palms over with thick bands of cartilage, and you tried again.

Now the grip seemed cold as death, and it was just as heavy. You lifted, and your elbows locked, and you grasped the pommel to try to steady yourself. You tried a new trick—you slipped a narrow ribbon of bone up from your living metacarpal and eased the fragment gently around the flexor tendon, and you pierced it through the back of your hand. You didn’t flinch. It was never your way. From there you unfolded long fingers of bone to grasp the handle, then more, to grasp it again; you lifted it, in a manner of speaking, assisted by a seething, clattering basket of eight phalanx articulates.

So now you could wobble the sword up in an obtuse angle before yourself. You waited. You felt nothing: no understanding, no mastery, no knowledge. You were just a necromancer, and it was just a sword. It fell away from your hands and clattered to the floor, and you folded in half, and you upchucked violently all over the hospital tiles.

There were many uniformed people in that room, but they were used to these antics. Harrowhark the First, ninth saint to serve the Emperor Undying, might throw up as much as she cared to. You were a walking sacrament, even if your early contributions to Lyctorhood seemed to be finding new and different ways to puke. They only intervened if it looked like you might choke to death on your own vomit, a mercy that you always vaguely thought a shame.

* * *

The first time the man you called God had delivered you the sword—in what seemed to you his aspect of the Kindly Prince, intending only gentleness—you’d fallen into a deep stupor from which you had never really risen. Maybe the sword had reified your grief into six feet of steel. You had loathed that thrice-damned blade from sight, which might have been unfair before you knew it loathed you in return.

You kept trying to wield it, all the same. Each touch ended with the contents of your stomach splattered colourfully on the floor. Your days dissolved like ashes in front of a fan—scattered beyond any hope of retrieval—blown back into your face or fluttering upward beyond your grasp. Sometimes you would rise, and you’d take up the blade, as though in expectation of something. Nothing ever happened; you felt nothing except the sword’s enormous, empty hate of you, which you knew to be real, even then. You and the sword would seethe in your mutual bitterness and fury, and then you would end up with blistered hands and a floor’s worth of vomit.

Details sat at awkward angles to one another. You’d been in this bed some time, wearing clothes that weren’t yours. Occasionally ticklish rasps at your ears or forehead would frighten you numb before you realised it was your own hair. Away from Drearburh shears, it grew in a way that was almost debauched. You would cut it yourself and still find irregular little licks of it tucked behind your ears—or maybe you had not cut it at all. Sometimes, in reaching up to it, you would then recall that you had no robe or skeletal mask. Nobody had given you any paint and there wasn’t a stick of grease on board the whole ship, though even if there had been it would not have been blessed properly. The first time this happened, in your hot upset and shame, you ripped a sheet to shreds and covered your head with that. This still left most of your forehead nude, discounting the hair. Also, you were wearing a bedsheet. You took the poetic way out and used a black vestal’s last-choice gambit: you opened a vein and, trembling neither from pain nor blood loss, daubed blind upon your skin the sacramental skull of the Inglorious Mask.

The uniformed attendants were always busy with things that weren’t you. Sometimes you were humbly prevailed upon to sit up and part your ad-hoc veil to struggle through a bowl of clear soup, though those memories were doubtful fragments. It did not seem right that you could ever eat again. Sometimes people would move all around you, and you lay supine on your cot, astonished and shivering before the vista of stars out the window. The thick plex barrier seemed too light and frangible to keep you safe. Beyond it the great black throat of space bared itself to you, which frightened you beyond sense. At these times you fell in and out of sleep, somehow. You had long since ceased to care for human voices, which only talked nonsense: they would murmur their prayers of Three thousand units—replenish, that’s on the provision list—dump that stock, munitions will take it.

In your old life you might have been curious. But other noises haunted you, quite apart from the ones occurring to your ears. There was a great unmusical straining aboard ship—the sounds of wet drums—which had panicked you before you’d realised, with settling calm, that you were hearing the heave of seven hundred and eight beating hearts. You heard seven hundred and eight brains, thrumming in their cerebral fluid. You knew without checking that three hundred and four of those straining hearts belonged to necromancers; a necromancer’s heart myocardium flexed differently to your ears, worked worse, squeezed more feebly. You were sensing the living. Once you worked out what you were hearing, you became aware of everything immediate to you: the dust settling on the gleaming black plaques of the floor; the roiling of your pulmonaries; the soft marrow of your bones sucking up oxygen. Despite all this cacophony, you could not stay awake.

Sometimes you found yourself standing, gorge risen, staring at the great sword left untidy and naked on the floor. You would not remember rising. You would not remember how you had come to be there. Sometimes you would forget who you were, and at recalling yourself, weep like a child.
