The Spire was beautiful at night. But on nights like tonight, it was something else entirely.
From our window in Ring Three I could see the light at the Spire's peak — cold clinical gold, steady and indifferent. Below it, the rings of Lumen stepped down in their concentric circles, each one threaded tonight with lantern-light and procession, the sanctioned vigil moving through the streets in its orderly way.
The Order called it the Night of Stillness.
My father had called it something else, once.
I was five or six. He stood at the kitchen window with a candle in his hand — not an Order candle, just a stub of beeswax he'd found somewhere, the cheap kind that smelled like nothing. He set it on the sill and lit it. Stood looking at it for a long moment, hands at his sides, then said the word quietly — to the candle, to the window, to something that wasn't in the room.
Apophrades.
I asked what it meant. He looked at me then — really looked, the way he did when he thought I'd asked something worth answering. The dead come home tonight, he said. We leave the door open so they can find us.
My mother came in from the hall. He didn't say it again.
We were four rings out from the centre. Far enough that the surveillance runes on our building were standard-issue rather than custom. Close enough that we could see exactly what we weren't.
I had been watching the Spire from this window for five years. I had never once felt like the vigil was for us — even though we were born in the middle of it, even though every year the city lit its lanterns on our birthday without knowing or caring that it was our birthday. Eighteen years of sharing the night with everyone and belonging to none of it.
I had never stopped finding it ugly.
They said things about what lived beneath Lumen. Everyone did, in the particular way of things nobody wanted to look at directly — sideways, in fragments, in the careful language of people who had decided the less said the better. That the people who went down didn't come back right, if they came back at all. That the water did something to you. That whatever was left of the people who'd fallen through the city's cracks had stopped being people in any way that counted — had gone feral in the dark, had lost language and reason and anything that might be called a life.
That the dead didn't stay dead down there.
I had grown up with these stories the way you grew up with anything told in low voices — half-believing, half-dismissing, certain only that the under-city was somewhere you didn't go. Somewhere things went when Lumen was done with them. The Order didn't name it in official documents. It simply wasn't there.
We called it the Errata, the way you'd name anything you didn't want to look at for too long.

Eirene made the cake.
She did it the way she did most things — with the full weight of her attention and a complete lack of ceremony. Flour on her forearms. The recipe she'd long since memorized open anyway on the counter, because she liked having it there.
I sat on the counter beside the sink and handed her things when she asked. I didn't ask where she'd gone last night or the night before. It was our birthday. I had made myself a promise.
The kitchen smelled like vanilla and something slightly burnt where she'd gotten distracted. The rail passed overhead at its regular intervals. Outside, the Order's vigil moved through Ring Four with its lanterns and its approved hymns and its careful pretense that tonight was simply tonight.
For a little while, none of that existed. Just the two of us in the too-small kitchen, the cake taking shape between us.
I watched her the way I always watched her when I thought she wasn't looking.
There was something different about her this year — something I couldn't name, had been trying to name for months. Not different-wrong. Different-settled. Like she had made a decision that had weight to it, that had changed the specific gravity of how she moved through a room. She laughed easier. She slept harder. She had started humming to herself when she thought she was alone, low and tuneless, in a way she hadn't done since we were small.
I didn't know what to do with that. So I watched her instead. Waited. Told myself I wasn't counting the days.
We sang under our breath while we frosted it — the old counting song, the one we'd learned before we knew what we were, before the Order had language for us, before the word deviation had ever entered a room we were standing in. Her voice was low and steady. Mine found the harmony without thinking, the way it always had.
Eighteen candles. We lit them all.
The kitchen was small enough that four people sharing it constituted a crowd, and we were four — Mother moving around the edges with the careful efficiency she'd perfected over five years of making herself smaller in spaces she'd never quite claimed. Father at the table with his hands around a cup he hadn't drunk from, looking at something in the middle distance that wasn't in the room. The cedar block sat beside his elbow where it always sat now, the nick in the grain still uncorrected. I had stopped looking at it directly the way you stop looking directly at certain kinds of damage. Peripherally. Just enough to know it was still there.
Eirene blew out the candles on the first try.
She always did.
I made a wish anyway. I didn't tell her what it was.
—-
The fight started because she began packing.
Not loudly. Not dramatically. She just crossed to the wardrobe after dinner and started pulling things out with a quiet, practiced efficiency that meant she had done this many times and knew exactly what she needed. The specific competence of it was what got me — not the leaving, not even the lying, but the practice of it. How many times.
The candles on the table had burned down at exactly the same rate all evening. I noticed it without noticing it — the way you notice that the window isn't rattling, that the pressure in the room feels settled, that everything is working the way it's supposed to. It was just Eirene being in the room. It was always just that.
"Where are you going."
Not a question. I had learned not to make them questions.
She didn't look up. "Out."
"It's our birthday."
"I know."
The frosting was still on the counter in its bowl. Mother had gone quiet in the way she went quiet when she wanted to be furniture, and Father's hands hadn't moved, and the cedar block sat in the lamplight with its uncorrected nick and I looked at it for a moment and then looked away.
Say something real, I thought. Just once. Just tonight.
"Eirene."
She folded a dark scarf. Set it in the bag. Kept moving with that same practiced efficiency, not looking at me, not pausing. She had dressed for the dark — everything she was packing was dark, I noticed that now, the kind of colors you wear when you don't want to be seen.
"I'll be back by morning."
"You said that last week."
"And I was back by morning."
"At dawn. You came back at dawn and you smelled like—" I stopped. "Like somewhere. Like somewhere that isn't here and isn't anywhere I know."
She finally looked at me.
Her eyes were the same as mine and completely different from mine, the way everything about us was — same green, same angle, same bone structure underneath, but hers carried something mine didn't, some quality of settled certainty that I had spent eighteen years either admiring or resenting depending on the day. Tonight I couldn't tell which.
"I'm careful," she said. "I'm always careful."
"That's not what I asked."
"I know."
"You've been lying to my fucking face," I said, quietly. "For months. And I just kept waiting for you to stop."
The room went very still.
Eirene set down what she was holding.
"I'm trying to protect you," she said.
"From what."
"From—" She stopped. "It's not safe. What I'm doing. If you knew and the Order—"
"Tell me what you're doing."
"I can't."
"Can't or won't."
She didn't answer. That was its own answer.
Just say it. She never just said it. I had learned to stop expecting that she would.
"You come back smelling like somewhere I don't know," I said. "Every time. For months. And you look at me like I'm—" I stopped. Started again. "Like I'm something you're protecting. Like I'm the thing you're keeping safe from whatever you found."
"You are," she said. Simply. Like that was supposed to help.
"I don't want to be."
She reached up and tucked her hair back — the gesture she made when she'd already made a decision and was waiting for the conversation to catch up.
"Not yet," she said. "I'm not ready to tell you yet."
I had been hearing that for months. It had a specific weight by now, a specific shape — the shape of a door that might never open, of a promise that kept moving forward the way horizons do when you walk toward them.
"Is it a boy?" I said.
She didn't look offended. She looked tired.
"No," she said. Immediate. Too immediate to be rehearsed. "Of course not."
The certainty of it disoriented me more than anything else she'd said.
"Then what is it."
She hesitated — not over the answer, but over the permission to give it.
"It's not a person," she said quietly. "Not the way you mean."
That was worse.
"Then tell me."
"I can't."
"If you loved me," I said, "you'd stay."
I said it quietly. Like a conclusion I'd already reached.
Eirene went very still.
The silence held for three seconds, four. Her face did something I had no name for — not hurt, not quite, but something below hurt, something structural.
She finished packing.
She picked up the bag.
At the door she stopped, and for a moment I thought she would turn around. Her hand rested on the frame. Her shoulders were set.
She left.
The door closed behind her with the soft, final sound of a room that had given up one of its people.
—-
For a moment I stood there, staring at the door like it might open again out of sheer stubbornness.
It didn't.
I went back into the bedroom because there was nowhere else to go. Because standing in the kitchen with Mother pretending not to listen and Father pretending not to exist would have broken something I didn't have the energy to fix.
Her side of the room still held her shape. The drawer she'd closed too quickly. The bed slightly rumpled and the faint smell of damp stone, something green I couldn't name.
I told myself I wasn't searching.
I opened the top drawer anyway.
Her sketchbook wasn't there.
That was wrong.
I checked beneath the mattress. Under the desk. The hollow behind the loose baseboard we'd used when we were twelve and convinced we were clever.
Nothing.
Then I saw something. Folded once. Tucked beneath the wooden bird on her pillow, like she hadn't meant to hide it so much as anchor it.
My name wasn't on it. It didn't need to be.
I unfolded it carefully, because my hands were shaking and I didn't want to give that away to an empty room.
Three lines.
If something goes wrong, find the Root Singer.
She listens to what the stone remembers.
Trust her.
No location. No explanation. No apology.
Root Singer.
I read it three times. It sounded like a story you told children. Like something you invented to make the dark feel older than it was.
She listens to what the stone remembers.
The stone doesn't remember anything, I thought. The stone is stone.
I found her sketchbook under the floorboards — hidden where we'd hidden things as children, where she knew I'd look eventually. Documentation of restoration magic. Careful studies of my void, the way it moved, the way it damaged. Page after page of notes about repair.
I looked at my hands. The gold scars were unnaturally even — not the ragged texture of wounds that had healed on their own, but something more deliberate. Someone had held each cut closed until it knit correctly. I'd never thought to ask why my body healed so cleanly when everything else about me leaked.
I folded the note along its original crease and slipped it into my coat pocket before I could decide not to.
I stood at the window.
Below, the city was still keeping its vigil. Lanterns in the rings, processions moving their careful routes, the Spire's light burning gold against the dark.
In the Cold Coast, my father had told me once, there was a hill behind the house where you could see the whole valley. On Apophrades the valley's candles burned in every window — small and personal and nobody's business but the families who lit them. You left the door open. You said the names out loud. The dead came home.
He said it quickly, quietly, in the particular tone of someone spending something they knew they only had a little of left.
I had not heard him say anything like it in years.
Passing through the residential corridor on my way out, I saw a maintenance notice I'd walked past a hundred times without reading. Stability rating: Nominal. No fluctuations recorded in Sector 7 for the past four months.
Four months. The same length of time Eirene had been making her secret trips.
I filed it without understanding. Kept moving.
—-
I turned away from the window.
Don't, I thought. Don't you dare just stand here.
I crossed to our bedroom. Knelt beside my bed. Pulled the bag out from underneath.
I had packed it six weeks ago. Then repacked it three weeks later when I realized I'd included things I wouldn't need and hadn't included things I would. The weight was right now — I had checked it more times than I cared to admit. Two days of food at half-rations. Canteen. Change of clothes rolled tight. Headlamp. A small kit of bandages and antiseptic. The things a careful person brings when they don't know what they're walking into. The leather pouch from the floorboard, heavy with coin I had been slowly supplementing for months without letting myself think about why.
I had told myself it was a precaution.
I had been lying to myself with the same fluency Eirene had been lying to me.
I pulled on my coat. Sling over one shoulder. Door open, then closed behind me without looking back.
I went after her.
—
The service corridor beneath Ring Four was the kind of place designed to be forgotten — maintenance access, functional and dim, the sort of infrastructure that kept everything above it running and expected no acknowledgment for doing so. Bioluminescent moss grew in the seams between metal panels, casting a thin blue-green wash that was just enough to navigate by. Steam hissed in the pipes. The smell was metal and burned oil and underneath both something older, earthier, drifting up from below.
I had known about this corridor for two years.
I had found it eight months ago — followed Eirene to the building entrance once, lost her inside, and spent an afternoon systematically working through the basement until I found the maintenance access. I had stood at the top of it and looked down into the dark and gone back upstairs. Twice since then I had stood at the same spot and made the same choice. It had felt rational each time. It had felt like caution rather than cowardice.
I was done making that distinction.
I kept her in earshot, not eye line — far enough back that she wouldn't hear my footsteps beneath her own, close enough that the faint sounds of her movement reached me. She walked with the particular rhythm of someone who knew exactly where they were going. The confidence of it ached. Months of this. She had learned this dark the way I learned our apartment — by coming back enough times to stop being afraid of it.
The corridor descended. Branched. Descended again.
The moss gave way to something else — bioluminescent fungi in the mortar cracks, blue-green and gold, casting light that had no business being beautiful and was anyway. The air changed: less metal, more earth, something organic and alive threading through the cold.
I thought about what they said. That the people down here had lost themselves — that there was nothing left of whatever they'd been before, nothing recognizable, nothing that could be called civilization. That the water made you mad. I kept one hand against the wall and followed the sound of her footsteps and tried not to think about what was waiting at the bottom of this.
Ahead, Eirene's footsteps. Steady. Unhurried.
Don't lose her, I told myself. Just don't lose her.
I didn't lose her until the junction.
Four passages radiating outward from a central point, the stone older here — pre-Spire stone, the kind that predated the Order's architecture entirely. Eirene's footsteps ahead, and then a turn, and then silence.
I reached the junction and stopped.
Listened.
Nothing.
Something stirred in my chest. Not panic — I knew panic. This was quieter. An orienting, like a needle finding north. I didn't know what it was orienting toward. I pushed it down and kept walking.
The four passages looked identical in the fungi-light. No chalk marks, no worn stone I could read, no difference between them that my eyes could find. I picked the one that smelled most like the organic thread I'd been following — the living smell, the growing smell — and walked for two minutes until the passage ended in a collapsed section, rubble and old stone.
Back to the junction.
Second passage. Third. Fourth.
Each one either dead-ending or opening into spaces where the sounds that reached me were wrong — too many people, too much noise, nothing that felt like Eirene's particular quality of movement.
I stood at the junction and the facts arranged themselves without being asked. She was gone. The passages above me had dead-ended or locked me out. The bag on my back was the only reason I wasn't simply going to die of it.
I sat down on the stone floor.
The fungi cast their impossible light across the junction walls. From below — from somewhere below, through passages I hadn't tried yet — sounds drifted up. Voices. Laughter. A rhythm that was definitely music, low and percussive. And underneath it, threading through the stone, something I recognised before I understood why I recognised it: warmth, and names spoken aloud, and the specific quality of a night that had been given back to the people it belonged to.
Not feral. Not silent. The sounds drifting up were alive — voices and laughter and music, the opposite of everything I'd been taught to expect.
My father's word surfaced from wherever I'd been keeping it.
Apophrades.
I was sitting in the middle of it and could not have been more outside of it.
For a moment — just a moment — I wanted to go toward it. Not for Eirene. Just for the warmth. Just to be somewhere that was keeping the night the way it was supposed to be kept.
The want lasted exactly as long as it took me to recognize it.
I had come down here with a bag packed for weeks and a fight still raw in my chest and the last thing I'd said to my sister burning in the back of my throat.
If you loved me, you'd stay.
I sat with that for a moment. Sat with the specific ugliness of it. The way she'd gone still. The look on her face before she'd put the wall back up.
She had been holding things together my whole life — the apartment, my wounds, our family — without me ever noticing. And I had held that particular wound open and aimed at her.
I had spent eighteen years watching Eirene fix things I'd broken.
It had not occurred to me, until this moment, that I had been one of them.
The sounds drifted up from below like something breathing.
I stood up. Tightened the bag straps. Switched on the headlamp and let the clean white beam cut through the fungi-glow.
She went down because there was nowhere else to go.
So would I.
