Chapter 24
KAVOR
The thing beneath the pool opens its eye.
White-gray light is held inside a shape that has no name in my people’s teachings. Angular ribs fold away beneath the water, revealing a hollow center where blue pours inward.
Epis light. Sera’s blood-light. The sample’s frantic pulse. The unfinished bond between us. All answer. All are seen.
Sera turns in my arms, one hand still braced against my chest, her bandaged arm held tight against her ribs. Blue light glows through the blood-soaked cloth and spills into the sample pouch like a thread pulled between wounds.
The pool shudders. Far beneath the water, something moves again. Long. Vast. Not zemlja.
The zemlja has weight. Pressure. Hunger. A body that belongs to Tajss, even when it kills. This is different. This motion has no breath in it. No instinct. No life I understand.
Sera whispers, “Kavor.”
I hear what she does not ask. Yes, I see it. No, I do not know what it is. Yes, it has noticed us. No, we should not remain here when it finishes waking.
The wrong rhythm returns through the channels. Once. Pause. Again.
The eye beneath the pool pulses faster. It is not only calling zemlja now. Calling the reservoir. Calling the source. Calling whatever the glow found in us.
The sample at my chest flares so brightly the cloth cannot hide it. Sera flinches, and I feel the answer in her body before I understand the movement. Pain. Cold-bright and sharp, cutting through her wounded arm.
I shift my hand from her waist to her shoulder, steadying. Not holding. Not trapping.
She grabs my wrist anyway. Choice. A fierce little claw in the dark.
“What is that?” she asks.
Her voice is thin but steady. I look at the eye under the pool, at the blue light pouring into it, at the blackened channels around the reservoir starting to wake one by one.
“A heart,” I say.
The word tastes wrong.
“Machine heart?”
“Network heart.”
Her fingers tighten around my wrist. “Of the reservoir?”
“Perhaps.”
“Useful perhaps, or panic perhaps?”
“Old perhaps.”
She swears under her breath.
The cavern shivers again. High above, strands of epis turn toward the pool in slow waves, all blue-purple light bending to the white-gray eye. Where the pull is strongest, tips blacken. The drain we slowed begins to re-form through other channels, smaller now but multiplying.
We broke one tooth. The mouth has many.
“We need to leave,” I say.
Sera does not argue. That frightens me more than refusal.
Her gaze moves over the cavern, the pool, the blackening channels, and the old structures half-buried in glowing waste. I see her counting. Not food this time. Not rations. Loss.
How much can be saved. How much must be abandoned. How much hope the City can hold before someone takes it.
“We need proof,” she says.
“We have proof.”
“The broken anchor, the sample, the residue thread. Not enough.”
“Sera.”
“Not enough to make them understand this.” She gestures with her good hand toward the pool, the eye, the enormous, impossible glow of the reservoir.
“If I say there is abundance under them, they will hear salvation. If I say it is being drained, they will hear delay. If I say wait, test, map, decide carefully, they will hear only that I am standing between starving mouths and food.”
She is right. I hate that she is right. The City will hear epis, and hunger will become law. The Council will argue ownership over a thing already being stolen by something under their feet.
And Sera will stand in the center of that wanting. Her blood glowing. Her wound answering. Her body, turned by need into another resource.
No. The red rises, and I push it down until my claws ache.
“What proof?” I ask.
Her eyes flick to me.
Surprise, then something softer. She expected refusal. I give none.
“The map,” she says. “We mark the reservoir shape, the pool, the old structures, the corrupted channels. We take a visual record from here if we can. A strand from the blackened area and one from healthy growth.”
“No.”
Her expression sharpens. “That was fast.”
“Healthy growth, yes. Blackened area, no.”
“We need comparison.”
“The blackened area moved when the signal pulsed. It may contain the same filaments as the thing that cut you.”
“Then we contain it.”
“No.”
“Kavor.”
“No.”
The word lands too hard. I hear it, and so does she. Her face closes by one careful layer.
I loosen my hands at once. “Not as command.”
“It sounded muscularly command-shaped.”
“Yes.”
“At least you know.”
“I know the blackened growth is not worth your blood.”
Her eyes flash. “My blood is not the only blood available.”
“No.”
“There it is again.”
“Sera.”
“You just decided yours is acceptable.”
“Yes.”
She stares at me. I cannot lie. Not to her. Not now.
The eye beneath the pool pulses. Blue-white light pushes through the water, painting the underside of her jaw, her throat, the stubborn line of her mouth.
Beautiful. Alive. Angry with me. Good. Anger means she is still here.
“I am larger,” I say.
“And apparently dense enough to have your own gravity.”
“I heal faster.”
“That does not make you disposable.”
“No.”
“Say it like you believe it.”
The cavern hums around us.
I look at the old machine heart, the reservoir, the glow that recognized us too soon. I think of the caverns. Of males teaching one another to endure because no other future remained. Of sacrifice wearing honor until no one could tell the difference between courage and surrender.
Sera sees the thought move through me. She always sees too much.
“I am not disposable,” I say.
The words feel strange. Stone does not often speak of its own value.
Sera’s expression flickers. “Good.”
“But I am still taking the blackened sample.”
“Kavor.”
“Not because I am disposable. Because my skin is less wounded. Because I can seal it. Because if it reacts, you can pull me back.”
She glares, but the glare weakens at the edges. She dislikes reason when it does not belong to her.
“I pull you back?” she asks.
“Yes.”
“With one good arm?”
“And a bad temper.”
“That might work.”
“Yes.”
The almost-smile comes before I can stop it from forming. Her eyes catch on my mouth. The pull between us tightens. Not the bond. Not yet.
Want, braided with danger and with the memory of her mouth. Her knees on either side of me. Her voice saying, I want this. I want more than I know what to do with.
My body knows exactly what to do with wanting. My hearts do not. Both are traitorous.
The machine beneath the pool pulses again, breaking the moment.
Sera turns away first. “We do this quickly.”
“Yes.”
She retrieves the map from my pack one-handed and spreads it across a dry stone shelf. Her fingers move fast. Too fast. Pain tightens her mouth, but she does not stop. I want to tell her to slow. I do not.
She marks the reservoir with hard, efficient strokes. Ridge. Pool. Arch. Anchor site. Black channels. Healthy growth. Possible exit lines. Old district structures. She draws the cavern as if she is cutting a truth into the page so no one can pretend later.
I watch the pool. The eye watches us. At least that is how it feels.
Sera finishes the main marks and tears a thin strip from the map edge, using it to label the broken anchor pouch, the gray thread, and the sample. Proof, organized while the underworld opens its mouth.
Very Sera. Very human. Very fragile. Very terrifying.
“I need the healthy strand,” she says.
“I take it.”
“No, I do. You have anchor burns.”
“Minor.”
“Pain bad?”
“No.”
She narrows her eyes.
“Less than pain bad,” I say.
“Better.”
The healthy growth is close enough to the ridge to reach. A small side strand bright with blue and purple, not rooted in a central cluster. Sera reaches for it, then stops herself before touching.
She looks at me. I offer my knife. She takes it. Careful. That small act should not matter. It does.
She cuts the strand the way she watched me do before. Not too close to the root. Not too much. A tiny piece only. She wraps it in treated cloth and marks it with a fierce little knot.
The strand pulses once in her hand. Blue answers beneath her bandage. She freezes. I step closer.
She lifts her gaze to mine. “Do not.”
I stop. The glow fades. She breathes out.
“So that keeps happening,” she says.
“Yes.”
“I hate that.”
“No,” I say.
Her eyebrows rise. “No?”
“You fear it.”
“That is different?”
“Yes.”
Her face shifts. I see the place where the words land. Fear is not hate. Want is not theft. Care is not control. We are both learning dangerous distinctions in a cavern that may kill us before we use them.
The machine beneath the pool opens wider. A low vibration rolls through the cavern floor. Far below, the zemlja answers. Closer. Not under us yet. But turning toward the reservoir.
The signal has more than one purpose.
Call zemlja. Drain epis. Open old channels. Perhaps forcing the creature through buried structures until the City cracks from beneath.
“We are out of time,” I say.
“Black sample first.”
I move before she can.
The blackened growth lies where the corruption has reached the ridge wall near the old arch. It is not fully dead. Some strands are black at the tips and blue at the roots, with a sick white line flickering between. The wrongness inside it waits.
I use the torn anchor wrap as a barrier, then cut the smallest piece I can. It twitches. Not much. Enough. Sera inhales behind me.
“I saw it,” she says.
“Yes.”
“Do not put it near the healthy strand.”
“I know.”
“Or the gray thread,” she says.
“I know.”
“Or the blood-light sample.”
“Sera.”
“I am being thorough.”
“You are frightened,” I say.
“Yes,” she snaps. “And thorough.”
Truth with teeth.
I seal the blackened strand inside a separate scrap of hide, then wrap that in mineral cloth, then in another hide strip. Not perfect. Enough for now. Nothing on Tajss is perfect except the timing of disaster.
The eye under the pool flashes. The entire cavern goes white-blue. For a single breath, the world vanishes. In the light, I feel Sera. Not see it. Feel it.
