The attack came at dawn, at the worst possible time, which was how attacks preferred to arrive.
Kairu was on the eastern outskirts of the city where the buildings thinned and the city wall had a gap — not a breach, just a section under repair, boarded over with timber that was doing an optimistic job of suggesting it was a real wall. Yumi had sent him here at first light with a list of specific instructions: walk the perimeter, identify the patrol patterns of the city guards, note any locations where the wall's integrity was compromised. Reconnaissance, she called it. Useful work that would keep him occupied and away from Borro's shop while she negotiated the terms of their return visit.
He understood he was being managed. He went anyway because the instructions were sensible and because standing still made the almost-sound louder.
The Husk came over the timber boarding at the gap in the wall.
Not one — three. Low to the ground, moving fast, the animalistic hunger-driven scramble of the lowest demon tier. Husks were not intelligent. They did not adapt or strategize or assess. They moved toward warm living things with the single-minded momentum of water finding a drain, and they were fast, and there were three of them, and Kairu had the Ashblade drawn before the first one closed half the distance.
The first one he killed cleanly — or as cleanly as he did anything, which was with more instinct than technique and the blade doing the meaningful work. The red pulse traveled the steel, the soul-core was consumed, the Husk came apart. Ten seconds.
The second one he killed less cleanly, taking a hit across the ribs that cracked at least one of them and sent him into the wall hard enough to see white for a moment. He killed it anyway because the blade had developed the quality of finishing things it started regardless of what the rest of him was doing. Fifteen seconds. Ribs screaming.
The third one he swung at and missed.
The blade passed through where the Husk should have been and the Husk wasn't there — had moved, not with the adaptive intelligence of a Shaped but with the simple animal reflex of something that felt the sword's intent before the sword arrived. The blade passed through empty air and continued in an arc it couldn't stop and the edge of it caught something at the Husk's feet — a shadow, or what he thought was a shadow — and the red pulse traveled the steel and this time it didn't stop.
It went into the ground.
The Husk froze. Then it came apart — fast, the way Husks came apart, without the thoroughness of a full devour — and what remained of it scattered and was gone. But from the place where the blade had caught the shadow, something was happening. The shadow was moving. Not the way shadows move when light changes — moving independently, pooling and reshaping with a quality of intention, rising from the ground in a column that was simultaneously shadow and smoke and neither.
Kairu stepped back.
The column collapsed.
On the ground where it had been, something sat.
It was small — roughly cat-sized, vaguely humanoid in the way that a smudge is vaguely humanoid if you look at it sideways and are already expecting something. It was made entirely of shadow — not darkness, shadow, the specific phenomenon of light being interrupted, which meant it had no fixed form and shifted constantly at its edges depending on where the light was coming from. It had two points of dim red light where eyes would be if it were a thing that had eyes.
It looked at the sword.
Then it looked at Kairu.
Then it said, in a voice like something speaking from the bottom of a well: "You absolute idiot."
Kairu stared at it.
"You hit me," it said. The voice had clarified slightly — less well-bottom, more the quality of someone speaking through cloth. Female, he thought, though the concept felt imprecise applied to whatever this was. "With that. With the devouring sword. You hit me with the devouring sword and now I am—" It looked at its own hands, which were shadow-hands, which shifted and blurred at the edges. "I am considerably less than I was five minutes ago."
"You were a demon," Kairu said.
"I was minding my own business."
"Attached to a Husk."
"Adjacent to a Husk. There's a distinction." It stood — or achieved the vertical orientation that served it as standing — and the red eye-lights fixed on him with an expression that shadow-things should not have been able to have but that was unmistakably irritation. "I was passing through. I do not eat people. I was passing through this particular piece of ground because this piece of ground is near a Veilcrack remnant and that's where my kind travel and I was minding my own business and you hit me with the devouring sword."
"So leave," Kairu said.
It tried.
He watched it try. Watched it move toward the wall, toward the timber boarding, toward the gap — and stop. Watched it try again in a different direction and stop again. The stopping had a quality of running into something invisible, the behavior of something that has reached the end of its tether and discovered the tether.
It turned back to him.
The red eye-lights had a new quality. Not irritation now. Something more complicated.
"I can't," it said.
"What do you mean you can't."
"I mean I can't." It looked at the sword in his hand. "The blade touched me. It didn't finish the devour — I'm not inside it, I'm not consumed, I am still me and I am still here. But the touch established a—" It made a sound of profound aggravation. "A connection. I am connected to the blade and the blade is connected to you and I cannot move past a certain distance from either of you without encountering what feels like a wall made of the fundamental structure of reality."
Kairu looked at the sword.
The almost-sound had changed quality. There was something in it that he could only describe, and only to himself, as amusement.
"Fix it," he said to the sword. Feeling extremely foolish.
The almost-sound continued, unchanged.
"It's not going to fix it," the shadow-thing said. "That blade doesn't undo things. It only does things." It sat back down on the ground with the resigned posture of something that has just accepted an unwelcome situation. "I'm stuck."
---
He stood in the growing morning light and looked at the small shadow-creature sitting on the ground beside him and ran through his available options, which were limited.
"What are you," he said.
"Murei. Low tier. I don't eat people, I don't attack settlements, I travel along Veilcrack remnants and consume ambient dark energy and I keep to myself." The red eye-lights regarded him steadily. "I've been doing it for a long time."
"How long."
A pause. "I don't remember exactly. Long." Something in its voice shifted when it said this — a texture he couldn't name, there and gone. "Time is different in Mureiga."
"Do you have a name."
Another pause, longer.
"Not anymore," it said.
He looked at it for a moment. Then he sheathed the Ashblade, which seemed like the right thing to do given that the Ashblade was apparently responsible for all of this, and picked up the pack he had dropped at the start of the attack.
"Can you keep up," he said.
The red eye-lights blinked — a gesture that required no physical eyes and therefore meant it was entirely intentional. "I don't have a choice, do I."
"I meant can you move fast enough. Without being seen."
It looked at itself. Shadow-form, constantly shifting at the edges, currently about as subtle as a cat-shaped hole in the world. "I can flatten," it said, after a moment. "Travel as shadow. On surfaces. If the light is right."
"Then travel as shadow. Stay close. Don't talk until we're away from the wall."
"Are you giving me instructions," it said.
"Yes."
"You hit me with a devouring sword and now you're giving me instructions."
"Do you want to stand here and discuss it."
The red eye-lights regarded him for a long moment. Then the shadow-creature flattened — folded itself down into two dimensions with a smoothness that was deeply wrong in a physical sense — and became, to all appearances, Kairu's shadow, trailing behind him with a slight wrongness in its shape that you would only notice if you were already looking for it.
From the ground, in a voice barely above a murmur: "This is humiliating."
"Quiet," Kairu said.
He walked back toward the city.
---
Yumi's reaction, when he returned to the room above the old man's building and told her what had happened, was to open her notebook and write in it for forty-five uninterrupted seconds while he stood waiting.
"Show me," she said, without looking up.
He looked at his own shadow on the floor. "Come out," he said, feeling foolish again.
The shadow peeled itself upward and reconstituted the small shadow-form, red eye-lights and blurred edges and the air of profound reluctant dignity that was apparently its default state. It looked at Yumi. Yumi looked at it, pen still in hand.
"Interesting," Yumi said. She was not speaking to either of them specifically.
"It's not interesting, it's a problem," Kairu said.
"Those aren't mutually exclusive." She addressed the shadow-creature directly. "Tier?"
"Low," it said. "And before you ask — no allegiance to any General-class, no connection to organized incursion activity, no information about current Murei movements worth mentioning." A pause. "I keep to myself."
"It said that already," Kairu said.
"I'm establishing it for the record." Yumi made another note. "Can it be used in combat?"
"I'm right here," the shadow-creature said.
"Can you be used in combat," Yumi said, without adjustment.
The red eye-lights considered this with what appeared to be genuine evaluation rather than offense. "I can interact with shadows and darkness. Manipulate them, to a limited degree. I can obscure. I can move through surfaces that shadow can move through." A pause. "I am not a weapon."
"Everything is a weapon," Yumi said, in the tone of someone stating a principle. "It's a matter of application."
"I like her less than I like you," the shadow-creature said to Kairu. "And I don't like you."
"What should we call you," Kairu said.
The question landed in the room and sat there. The shadow-creature went still in the particular way of something that has been asked something it did not expect and does not have a ready answer for. The red eye-lights dimmed slightly — not extinguishing, just retreating, the way a person's eyes go when they're looking at something internal.
"I told you," it said, after a moment. "I don't have one."
"You need one. We can't call you the demon."
"You can call me whatever you want. I can't stop you."
"Sable," Yumi said, without looking up from her notebook. "The color. It fits."
The shadow-creature looked at her. Looked at Kairu. Looked at its own shadow-hands with an expression that was, despite having no face to express it with, clearly the expression of something that has just been named against its will and is deciding how to feel about it.
"Sable," it said, trying the word.
"Yes," Yumi said.
"That's a color."
"Yes."
"You named me after a color."
"Would you prefer something else."
A long pause.
"No," it said, quietly. Then, quieter: "Sable is fine."
Kairu looked at the small shadow-creature — Sable — sitting on the floor of the room in the morning light, its edges blurring and shifting, its red eye-lights steady. He thought about what it had said when he asked how long it had been traveling. The pause before *long.* The texture in its voice that he couldn't name.
He didn't ask. It wasn't the time.
"Can you scout," he said instead. "Move ahead of us through shadow, see what's there."
Sable looked at him. "You hit me with a devouring sword two hours ago and now you want me to do reconnaissance."
"Can you or not."
The red eye-lights regarded him for a long moment with an expression that was irritation and something underneath the irritation that was more complicated and that he filed away for later.
"Yes," Sable said. "I can scout."
"Good." He picked up his pack. "We're going back to Borro's."
"Who's Borro."
"You'll see."
"Is he going to try to name me something."
"Probably not."
"Small mercies," Sable said, and flattened herself back into his shadow as he moved toward the door.
From the ground, already fading to a murmur: "For the record, this is still humiliating."
Kairu said nothing. But something in his chest — some tight and wound-up thing that had been wound up for eight days — loosened by a fraction so small it was nearly nothing.
Nearly.
