Lower Rings in the early morning had a particular quality of light that Seren had never been able to accurately describe to anyone who had not grown up in it.

The Vault shine reached the lower districts at an angle, filtered through the accumulated haze of the coal district and the charcoal workshops and the tallow rendering facilities and the communal heating vents that ran along the base of every residential block. By the time it arrived at street level in Lower Fifth or Lower Ashfield or the Tangent district where Seren had grown up, it had been strained of most of its direct quality and become something diffuse and yellowish, the color of old paper. Marked residents in High Ring complained sometimes about the quality of Vault shine on overcast cycles, meaning cycles when the dome’s luminescence was slightly reduced for maintenance reasons. They were complaining about conditions that Lower Rings residents would have considered a good day.

Seren had stopped noticing it years ago. This morning she noticed it again, because she was walking through it with someone who had grown up in the same light and who moved through it with the same practiced efficiency, and there was something about the parallel that made her aware of the light the way you became aware of something you had stopped seeing.

Alden walked slightly ahead, which was habit rather than discourtesy — he was reading the street as he walked, checking sightlines and cross-streets with the automatic attention of someone for whom the difference between the safe route and the less safe route was professional knowledge. He knew everyone on this stretch. Not by name, necessarily, but by pattern — the vendor who set up his tray on the south corner at this hour, the woman who crossed from the residential block to the water distribution point carrying the same two containers every morning, the group of young men outside the repair workshop who were not doing anything threatening but whose presence meant the workshop’s back exit was probably being used for something unofficial.

He did not narrate any of this. Seren simply watched him and understood it.

“Corvin’s sister,” she said. “She knows we’re coming?”

“She knows I’m coming. She’ll deal with you.”

“That’s reassuring.”

“She’s cautious. It’s sensible. Her brother is missing and the last person he was seen with is dead.” He glanced at her sideways. “She’ll be more comfortable once she knows you’re Records. People in Lower Rings have complicated feelings about Records, but mostly they want their paperwork handled correctly.”

“People in Lower Rings have complicated feelings about Records because Records is where their names go to get abbreviated,” Seren said.

Alden did not respond to this, which she took as agreement.

They passed the market stretch, which was already active — the early vendors with their carts of bread and preserved goods, the textile sellers laying out their stock on folding tables, the informal exchange points where people traded labor hours and ration supplements and the various commodities that circulated in Lower Rings at the margins of the official economy. Alden moved through it without pausing, acknowledging people with nods that were returned with the particular quality of acknowledgment that meant he was known here in the way that useful people were known: as someone who could be asked for things and who could be trusted to either help or tell you clearly that he could not.

At the corner of Lower Fifth and the Pipe Lane, they passed an older man sitting on a folded blanket outside a residential entrance. He was talking to a group of children who were eating their morning portions before the school registry call. Seren caught the end of what he was saying.

“— that’s why you don’t say things like that, because what’s outside is dead. All of it. The Vault is what keeps us breathing. You understand? Your grandmother’s grandmother was alive because of the Vault. You’re alive because of the Vault. Talking about going outside is like talking about cutting a hole in your own chest.”

The children were quiet in the way children were quiet when they were waiting for the authority to finish speaking so they could continue their actual conversation. One of the smaller ones was staring at the old man with the polite, blank attention of someone who had stopped processing the words and was waiting for their turn.

Seren watched them as she and Alden passed. The old man did not look at her.

After they had gone half a block, she said: “Did you ever think about it? When we were young.”

“Think about what?”

“Outside. What’s outside the Skyline.”

Alden was quiet for a moment. “Cassian talked about it once. Before.” He did not specify before what. He did not need to. “He said the reason they tell us it’s all dead out there is because they need us to believe it. I said, what if it’s actually all dead out there. He said, well, then we’re the same as before but with less hope.” He paused. “I thought about it after that.”

“What did you conclude?”

“I concluded I didn’t have enough information to know either way. I still don’t.” Another pause. “You?”

Seren thought about the bodies she had processed. The way the Vault shine came through the dome in the same grey-yellow wash every single cycle, without variation, because there was nothing behind it that varied — no weather, no seasons, no source that moved or changed. “I think,” she said carefully, “that I don’t know what’s out there either. But I’ve been writing down names of dead people long enough to notice that everyone dies afraid of the same things. The same two or three things. And not one of them is what’s outside the Vault.”

Alden did not respond. But he was listening. She could tell by the way he had stopped monitoring the street as carefully and was moving by habit instead.

They passed the old charcoal works on the way through to Lower Fifth.

Seren saw it out of the corner of her eye first — the sagging roof line, the warped boards, the particular lean of the eastern wall that made the building look like it was perpetually considering collapsing to the left. It looked worse than it had the last time she had walked past it, which was years ago, and the entry point that Alden had found was not visible at this angle.

She did not slow down.

Alden also did not slow down.

Neither of them said anything about it.

Corvin’s sister lived in a single-room dwelling on the third level of a residential block in Lower Fifth, accessed by an exterior staircase that groaned under weight in a way that was more performative than structural. Her name was Deva Ash and she was twenty-two years old and she had the look of someone who had been managing a sustained state of controlled fear for several months and had gotten very good at making it appear as something else.

She looked at Seren for a long moment before letting them in.

“Records,” she said. It was not quite a question.

“Ash Copyist,” Seren said. “The lowest tier. I process mortality records. I’m not here officially.”

Deva looked at Alden. He nodded slightly. She let them in.

The room had a window looking out onto the building’s interior courtyard. Deva had a cot, a table, two chairs, a small heating unit, and a shelf with three objects on it — a folded piece of cloth, a small carved wooden figure, and a tin cup. The walls had no decorations. The floor had been swept recently.

“He was asking about deaths,” Deva said, sitting on the edge of the cot. “Specific deaths. People who died in ways that didn’t match their records. He said he had found something in the Ashfield work records that didn’t add up.” She looked at her hands. “He always noticed things like that. He was good with numbers. He would have been good at your job,” she added, to Seren.

“What specifically didn’t add up?” Seren asked.

“He didn’t tell me. He said it was safer if I didn’t know details.” She was quiet for a moment. “He said he had met someone. Someone Marked who was also asking questions. He seemed scared of him and also… like he thought this person might actually be able to do something about it. Because he had access to things Corvin didn’t.”

Seren and Alden looked at each other briefly.

On the way back through Lower Fifth, they were stopped by a tangle of guards running a document check at the intersection of Pipe Lane and the main east connector. Standard rotation, announced and therefore expected — but Alden’s movement papers were Underways contractor documentation, which was valid for the lower districts but not technically for Middle Ring access, and they were currently at the boundary edge.

“Affiliation?” the guard said to Alden.

Seren held up her Records identification before Alden could answer. “He’s assisting with a cross-reference retrieval. Records support staff.” She kept her voice at exactly the register of someone who found this mildly inconvenient but entirely routine.

The guard looked at her identification, looked at Alden, looked back at her. Then he waved them through.

After the checkpoint, when they were far enough away that their voices would not carry, Alden said: “You lied for me.”

“I provided a characterization that was functionally accurate for the purpose of the interaction.”

“That’s a very Records way to describe a lie.”

“I process documentation professionally. I apply precise language.”

He was quiet for a moment. Then, so quietly she almost did not hear it: “Thank you.”

She did not say you’re welcome. She said: “Tomorrow. Same access point. I want to try the High Ring transition zone records before the cycle closes.”

Alden said: “Second watch.”

They split at the corner of Lower Fifth and the main connector without ceremony. Seren did not watch him go. She had four hours before she needed to be back at her desk, and a woman named Deva Ash who was waiting for her brother to come home, and somewhere in the Records building a routing card pointing at a room that was officially empty.

She walked back through the grey-yellow light and considered what she knew.
