Sam's apartment was on the fourth floor of a building that had no elevator and a stairwell that smelled like old wood and someone else's cooking. He had lived there for three years. He had chosen it specifically because it had one entrance, good sightlines from the main window, and a landlord who asked no questions.
He had never considered it home exactly.
It was a place he returned to. That was sufficient.
He stood in the hallway outside his door for a moment before going in — not hesitating, just preparing. The way you prepare before opening something you've been not-opening for a long time. You don't delay. You just make sure you're ready first.
Then he went inside.
The box was in the closet. Top shelf. Behind a tactical bag and two jackets he never wore. A standard moving box, sealed with packing tape that had yellowed over a decade, his mother's handwriting on the side in black marker: D + Y — Research Files, Archive 3.
He had moved it four times across four apartments.
He had never opened it.
Sam brought it to the kitchen table and stood looking at it for a moment. Then he made coffee — real coffee, not iced, the kind that took time — because he needed something to do with his hands that wasn't this yet.
He drank half the cup standing at the counter.
Then he opened the box.
The first layer was his father's — field notebooks, the compact kind that fit in a jacket pocket, filled with the dense shorthand that Sam had recognized on Krish's apartment wall. Seeing it here, in his father's hand, in a box that smelled of old paper and something faintly mineral — like excavated earth — was different from recognizing it on a crime scene. It arrived in a different part of him.
He set the notebooks aside carefully and kept going.
Maps. Printed and hand-annotated. Locations marked in a system that used symbols rather than labels — his mother's contribution, Sam recognized the logic of it. She had been the one who thought in encryption. His father had thought in narrative. Together their research had a specific quality — story and code intertwined.
Academic papers, some published and some not. A folder of correspondence — physical letters, which meant these were old, pre-email or deliberately off-network. Sam scanned the names on the letterheads.
K. Patel, Heritage Research Institute.
He stopped.
He pulled the letter out carefully.
It was dated fourteen years ago. His father's handwriting on the envelope. Krish's letterhead on the paper inside. The letter itself was methodical and warm — two researchers who had been exchanging information for some time, picking up mid-conversation. References to a previous meeting at a conference. A shared notation system that Krish had apparently passed on. A mention of a dig site that would appear later in his father's maps.
Your theory about the guardian families, Krish wrote, is closer than you might believe. I have reason to think at least two of the lines are still active. If you can get to Valdris before the winter season closes the region, there is someone there worth speaking to. Use my name carefully — the family is cautious with outsiders.
Sam read the letter twice.
Then set it down on the table and kept going through the box.
The photograph was near the bottom.
He found it in a manila envelope with three others — dig site documentation, his parents and colleagues in various configurations of fieldwork. But this one was different. His parents standing with Krish in front of a building Sam didn't recognize, all three of them looking at something off-camera, his mother laughing at whatever it was. A genuine photograph rather than a posed one. The kind that got taken accidentally and kept deliberately.
On the back, in his mother's handwriting: K.P. — Dravan site, Year 3. He knows more than he's saying. Trust him.
Sam turned it over and looked at the front again.
His mother was laughing.
He hadn't thought about that specific sound in years. He hadn't let himself.
He set the photograph on the table beside the letter and sat down.
The research his parents had accumulated was substantial — this was one box of what he assumed were several, the archive number on the side suggesting at least two others he didn't have. What was here was enough to establish the shape of what they had been building. The mythology of the fragments cross-referenced with physical locations. Guardian family names. Travel records to regions that mapped loosely onto what Krish had described in his recording.
They had been doing this for years.
They had been close.
The knock at the door was quiet. Two knocks, pause, one more — not a code exactly, just Sarah's particular rhythm, which he had apparently memorized without meaning to.
"It's open," he said.
She came in and read the room in the way she read all rooms — quickly, completely, without appearing to. Her eyes moved across the box, the papers, the photograph on the table, Sam's face.
She sat across from him without being invited.
He appreciated that. Being invited would have required him to decide whether to invite her, which would have required him to decide whether he wanted company, which was a question he wasn't sure he could answer accurately right now.
"They were already doing this," Sam said. The papers were spread across the table between them. "Before Unit 7. Before any of this existed officially."
"Yes," Sarah said.
"Krish knew my father. They worked together. Shared methodology." He picked up the letter. Set it back down. "They were building a map to the fragments. Fourteen years ago."
Sarah was quiet.
"And someone found out," Sam said.
The apartment held the sentence for a moment.
"You knew," Sam said. Not accusatory. Reading, the way he always did. "Not everything. But something."
Sarah's pause was exactly one beat longer than it should have been.
"I knew they were researchers," she said carefully, "who had been investigating something connected to the Outside. It was in the briefing when I was assigned to the unit."
"Assigned to the unit," Sam said. "Or assigned to me?"
Sarah met his gaze.
She didn't answer.
Which was, Sam understood, its own kind of answer.
He looked at the photograph. His mother laughing. Krish looking at something off-camera. His father's hand on a notebook, always a notebook.
"I'm not angry," Sam said.
"You're filing it," Sarah said quietly.
"Yes."
"That's not the same as not being angry."
Sam almost smiled.
"No," he said. "It's not."
He picked up the photograph and held it for a moment. Then he placed it carefully in his jacket's inner pocket.
"They were close to something," he said. "Before they died. The fragments, the guardian families, Valdris—" he tapped the letter, "—Krish pointed my father toward Valdris fourteen years ago. Someone there. A cautious family."
Sarah leaned forward slightly. "A guardian family."
"Has to be." Sam looked at the map spread across the table — his father's annotations, Krish's shorthand, a region marked in the northeast that matched the direction of the fragment's pulse from the recording.
Valdris.
"We need to get there before Seraphine does," Sam said.
"I know," Sarah said.
He looked at her.
"Thank you," he said. "For coming."
Sarah's expression shifted in the small, specific way it shifted when something landed that she hadn't entirely been prepared for.
"You left the door unlocked," she said.
"I knew you'd come," Sam said simply.
Outside, the city kept going.
On the table, his parents' work waited to be finished.
