The lower west corridor had the quality of spaces that existed for function rather than habitation: stone-flagged floor, no carpeting, the walls plain plaster with the kind of minor imperfections that indicated they had never been expected to be decorative. The light here was different from the main house — there were no east-facing windows, only a narrow high window at the far end that admitted a thin blade of grey morning light.

She found door forty-seven by the number plate rather than by any distinguishing feature of the door itself, which was the same plain timber as the others along the corridor. The key turned smoothly, which told her it had been used recently and regularly. Whatever this space was, it was not a room that had been locked and forgotten.

She went in alone.

The archive was not large. A room approximately the size of a generous study, with shelving along three walls and a single table in the centre. The shelving was partly occupied: not the dense accumulation of the records room, which had the layered density of decades of document accumulation, but the organised collection of a person who had been building something with a specific purpose. Files, some of them pulled from what she assumed were Ravencroft's main records and transferred here, others clearly assembled from external sources. Correspondence. Documents whose official homes were probably elsewhere in the manor's administrative system.

Each item had been labelled, in Cassian's hand, with a date and a brief subject notation.

Grace stood at the entrance of the room and looked at the shelves. Then she went to the table, sat down, and began.

She went to Elowen Marst first.

This was a decision she had made before she reached the room — not the most strategically important file, not the one most directly relevant to the question of her own origin, but the one she felt she owed a certain kind of attention to. Elowen had been here before her. Elowen had left the note in the wall, the music box, the diary with the torn pages. Elowen had tried to reach across the gap between one Grace and the next and had succeeded, and Grace wanted to know who had done that before she knew anything else.

---

The file was thicker than she had expected.

Not the standard intake document of a ward arrangement or a marriage contract — this had clearly been assembled over time, from multiple sources, with the specific quality of a file built by someone trying to understand a situation rather than record it. Cassian's annotations appeared throughout: marginal notes, connections drawn between documents, questions written in the narrow margin and sometimes answered in a different ink, suggesting they had been written at different times.

Grace read carefully.

Elowen Marst had not been born into House Marst. This she had already known from the brief reference in Cassian's working notes, but the file contained the details: she had been placed with the Marst family at age three, origin not documented in the official Marst records, the arrangement formalised through a legal instrument that described her simply as "a ward of uncertain provenance, accepted for care and education under the terms described herein." The same language, Grace noted, that appeared in the Velmira records concerning herself.

She read the next section. The education: beginning at age six, comprehensive and specific. Penmanship. Scent identification. Social protocols. The curriculum described was not the standard education of a noble ward. It was the curriculum she had received herself, named and structured and clearly recognisable. Whoever had designed the training programme had used the same template for Elowen that they had used for Grace — with the small variations that time and individual circumstance required.

She turned pages. The aromatic sensitivity documentation: several physicians' notes over the years, recording reactions to Winter Rose exposure that were consistent with what Grace had experienced herself. Elowen had been monitored. The monitoring had been part of the system — checking that the training was producing the correct physiological profile, the specific susceptibility that made the pharmaceutical preparation effective.

Grace set that page down and looked at the wall opposite her.

She was reading about herself. Not directly — different name, different house, different years. But the same template, the same monitoring, the same specific preparation for the same function. Elowen had been a prototype, in the technical sense: an earlier version of the same design.

She picked up the next page.

Cassian's own notes began about halfway through the file. The handwriting was slightly different from his marginal annotations — fuller, more deliberate, written sitting down rather than in the quick notation of a person reading through and responding. He had written them at a desk, thinking carefully about what he was putting down.

He had known about Elowen before she arrived at Ravencroft. Not everything — his early notes had the quality of a person assembling a picture from incomplete information, asking questions in the margins that he couldn't yet answer. But he had known the broad structure of what she was and what she had been trained for, and he had made a decision.

The decision was documented in his own hand: *E.M. does not know what she's been trained for. If I tell her, she may act without sufficient information and put herself in danger. If I don't tell her, I'm complicit in the continuation. I will begin finding a way to end this that does not require her to be harmed in the process.*

Grace read this paragraph three times.

Then she turned to the last section of the file.

The final document was a handwritten account, in Cassian's hand, of the night of Elowen's departure. Not dramatic — written with the flat specificity of a man recording something he needed to have on record. The plan had been Cassian's, in outline. The execution had involved two people besides Elowen: Cassian himself, and a woman who had been in the lower level of the Glass Garden that night for reasons the account described as "her own business with the Garden, separate from the Elowen arrangement and unknown to me until the night itself."

The woman had been attempting to leave the Garden with something — files, he thought, or a child, or both — when everything had gone wrong. Cassian had prioritised getting Elowen out. By the time Elowen was clear, he had gone back for the woman and found he was too late.

He had written, at the bottom of the account: *I did not know her name. I found out later. I have not been able to include it here because including it changes the nature of what I'm building and I am not yet certain I have understood that nature correctly. When I am certain, I will add it.*

Below that, in a different ink — newer, she could tell from the quality of the impression: *Mariel Vale.*

---

Grace sat with the file for a long time after she finished reading.

Mariel Vale. Not a name she knew. Not a name she had encountered in any of the other documents she had worked through. But the initials: M.V. Not L.V. — M.V. The name of the woman in the grave was not the name of the child. The woman and the child were different people.

She looked at the name on the page. Mariel Vale. Then she turned to the last page of the file, which she hadn't read yet, which she had been leaving for the end in the way she sometimes left the final piece of a difficult document because the end changed the meaning of everything before it.

At the very end, in Cassian's most recent hand — the ink freshest, the date just three weeks ago, just before her arrival: *Mariel Vale had one child. A daughter. Liora Vale. Current location: House Velmira. Current name: Grace Velmira.*

Grace set the file down on the table.

She put both hands flat on the surface of the table and looked at the far wall and sat with this.

Mariel Vale was her mother. Her mother had been in the Glass Garden the night Elowen escaped. Her mother had died in the Garden that night, or because of what happened that night, and had been put in the grave under Elowen's name, and Cassian had known this — had written her mother's name in a file he had then given Grace the key to — and had not told her directly, had let her find it here, alone, in the correct sequence, with the full context of everything else he had assembled.

She thought about whether she was angry about that. She examined the question carefully, the way she examined most things.

Not yet. She was not yet angry, not yet anything except very still, in the way of a person who has received information so large that the emotional response requires space and time she is not currently in a position to give it. She would be angry later, probably. She would be many things later.

Now she was sitting with Mariel Vale's name written on a page and understanding that the woman whose voice had been in the memory fragment — who had sung her name in a melody her body still remembered — had gone back to the Garden the night everything broke, and had not made it out.

She sat there for a long time.

Then she went back to the beginning of the file and read it again, more slowly, looking for everything she might have missed.
