The door opened.
It swung inward on whatever it was hinged on, smooth and without resistance, the way doors opened when they were simply doors and had been waiting to be opened. The dark beyond it resolved as her eyes adjusted, and the temple interior revealed itself by degrees.
It was larger inside than the facade had suggested. The ceiling went up further than it should have based on the exterior dimensions, and the walls were stone, old stone, the kind that had been here long enough to stop feeling like something built and start feeling like something grown. Braziers burned along the walls in long rows, low and amber, and the light they cast was the same quality as the light in Prometheus which Lilith noticed and filed away without knowing what to do with yet.
At the far end of the temple, seated, was the woman.
Lilith looked at her.
Or tried to.
The woman was there, a figure in a seat at the end of a temple with the brazier light moving across her but her face refused to resolve. Not obscured, not shadowed, not hidden behind anything. Just not quite available to Lilith's perception the way some things in this place weren't quite available. The shape of her was clear. The way she held herself was clear. The sense of her was very clear.
Her face was not.
Lilith stepped inside.
The door stayed open behind her. She walked the length of the temple toward the woman and stopped a few feet away and looked at the space where the face should have been.
The woman looked at her.
"Do you remember yet?" she said. Her voice was plain and direct, carrying no particular register beyond the weight of someone who had been waiting for a specific thing for a long time and was checking whether it had arrived. "Who I am."
Lilith's face did the thing it did when she was genuinely frustrated rather than strategically frustrated, the frown that went all the way to her forehead.
"How could I possibly remember," she said, "when there's — there's so much happening all at once." She gestured vaguely, which was not a gesture that accomplished anything but felt necessary. "We just arrived on Nocturne two days ago. Two days. And already there's an ancient entity appearing in a sealed room and staring at everyone with cyan eyes and the Librarians can't find any trace of it and Tu'Shan has put the whole fortress on heightened watch and I still have to figure out the training schedule and Eve needs—" She stopped. Breathed. "There's a lot happening. Is what I'm saying. There is a considerable amount happening and remembering who you are has not been at the top of the list because the list is very long and keeps getting longer."
The woman was quiet.
She had the quality of someone who had listened to longer speeches than this and had opinions about none of them.
Lilith stood in the temple and looked at the unresolvable face and thought about everything that had happened in the past several days and then thought about Lysander on a beach she'd never seen, and a gold cup, and a woman whose face had been beautiful and slightly wrong to look at directly.
She tilted her head.
"Wait," she said.
The woman waited.
"Were you the one who brought Lysander back?" Lilith said.
The woman smiled.
Lilith couldn't see her face but she could feel the smile, the way you felt certain things in dreams without seeing them directly.
"Maybe," the woman said.
"Maybe," Lilith repeated. Flatly.
"Maybe," the woman confirmed, with the serenity of someone who had decided that maybe was exactly the right amount of information for this moment.
Lilith looked at her for a moment. Then she looked around the temple. At the braziers, the walls, the ceiling that went too high. At the door behind her, still open, the forest visible through it.
"The door was always slightly open," she said. "Every time I've come here. I could have come in at any point."
"Yes," the woman said.
"But I didn't."
"No."
"Why can I come in now? What's different?"
"Nothing is different," she said. "You could have entered any time you wanted. It just wouldn't have meant anything until you were ready." A pause. "The door was never what was stopping you."
Lilith thought about this and all the times she'd stood at the threshold and turned away. She didn't have a complete answer for what had been different about those times. She set it aside.
"Someone is watching me," she said. "Something ancient. Cyan eyes. It came onto the ship during Warp transit and it followed us to Nocturne and it appeared in a briefing room and told the Chapter Master it was here because of me." She looked at the unresolvable face. "And something else told me I carry a fragment of the Emperor's soul." She kept her voice level. "Do you know anything about either of those things?"
The woman tilted her head slightly.
"I don't involve myself in the affairs of your world," she said.
Lilith narrowed her eye.
She looked at the space where the face was and tried to determine, using the skills she'd spent months quietly building, whether the woman was being honest or strategic or somewhere between the two.
The woman let her look.
She didn't shift or deflect or fill the silence with anything. She just sat with the quality of someone who found being examined perfectly comfortable and had no investment in the outcome.
She's not lying, Lilith thought slowly. But she's not telling me everything either. Those are different things. She genuinely might not know — or she genuinely might not consider it her business — which could both be true at once.
She was still working through this when the woman leaned forward.
Not far. Just slightly, the shift in posture that meant something was being said that the speaker wanted received properly.
"The knowledge you carried into this world," she said, "won't serve you much longer."
Lilith went still.
"What you knew of it. The surface of it, the shape of events, the names and outcomes; the world is already different from what you knew." She held Lilith's gaze, or did whatever it was she did that functioned as holding a gaze. "You being here has already changed things. Those changes will keep compounding." A pause. "What you knew will become less useful. And then it will become a problem."
Lilith sat with this. The honest, uncomfortable weight of it.
I knew this, she thought. I've known this was coming. The longer I'm here, the more I change things, the less the map I arrived with matches the territory.
"Then what do I do," Lilith said.
The woman sat back.
"Learn," she said simply. "Stop relying on what you brought with you and start relying on what you find." She paused. "And there's something else."
Lilith waited.
"There's a way to speak with me outside of this place," the woman said, more carefully now. "Not through dreaming. A different path. More difficult. It requires things of you that dreaming doesn't."
"What kind of things," Lilith said.
"That's part of what makes it difficult," the woman said.
Lilith looked at her.
"I'll make you a deal," the woman continued. "If you find your way to me through that other means — if you reach this place without sleeping — I'll tell you who I am." A pause. "Properly. Without maybe."
"And if I can't?"
"Then we continue as we have been," the woman said. "Which isn't nothing."
Lilith looked at the braziers. At the walls. At the ceiling that went too high.
"You're not going to tell me how," she said.
"No," the woman said.
"Of course not," Lilith said, to no one in particular.
The woman's amusement was felt rather than seen.
"The answer," she said, quieter now, almost offhand, "is already in what you have. It always has been."
Lilith opened her mouth.
She woke up.
The room was dark.
Not the darkness of the dream — the straightforward darkness of a stone room at night with the volcanic glow coming faint and amber through the narrow window. The fortress hum around her. The smell of old stone and recycled air.
She lay still for a moment and held the dream carefully, running through every detail the way she always did, locking it into the memory that never lost anything.
The knowledge you carried into this world won't serve you much longer.
If you find your way to me through that other means.
The answer is already in what you have.
She turned them over. Filed them. Let them sit.
Then she opened her eyes properly and looked at the room.
Lysander was asleep, face-down, one arm hanging off the edge of the bed. The Salamanders book on the shelf, the Sentinel standing guard beside it. Eve on her own bed, breathing slowly, still.
And by the door, in the chair, Ha'ken.
Awake. His posture was alert in the contained way Astartes were alert, the stillness of someone whose rest didn't look like rest. His red eyes moved to her when she sat up, registering her wakefulness without comment.
Lilith swung her legs off the bed and sat there for a moment, looking at her hands.
Tell him, she thought. That was the plan. Tell Ha'ken.
She thought about the fragment. About the cyan-eyed figure saying why do you carry a fragment of the Emperor's soul with the certainty of something that already knew the answer. About the Librarian using the word attention. About the woman in the temple saying she didn't involve herself in the affairs of this world, which could mean she genuinely didn't know or could mean she had decided not to, and Lilith still wasn't certain which.
The figure with the cyan eyes hadn't said it out loud in the briefing room. It had said it to Lilith alone, on the ship; quietly, privately, without anyone else present. It had come into a room full of Salamanders and a Chapter Master and said nothing about it.
Why? Lilith thought. If it didn't matter, why say it at all? If it did matter, why not say it where it would have had immediate consequence?
She turned this over and didn't reach a conclusion that satisfied her.
I don't have confirmation, she thought. I have one entity's word for it, an entity I can't identify, whose motivations I don't understand, who walked through a Geller field like it wasn't there. She looked at Ha'ken's silhouette across the room. But if it's true and if it's even possibly true, then not telling him is the same mistake I've already made before. And I said I was done making that mistake.
She thought about what the Imperium did with things it didn't understand. What words like heretic meant in a civilization built entirely around a single figure on a golden throne. She didn't know enough about how this specific claim would land. She didn't know if it would be treated as blessing or threat or something that got her handed to the Inquisition.
But she thought about Ha'ken kneeling in a medicae ward and meaning it. She thought about him standing outside an orphanage in a hive city having come because a nun asked him to. She thought about do not make me regret that choice and the way he'd said it, hurt rather than angry, the hurt of someone who had extended something real and found it handled carelessly.
He had earned this.
Whatever happened after, he had earned being told.
She got off the bed.
Her feet found the stone floor and she crossed the room quietly, past Eve's bed, past Lysander's, until she reached the chair by the door.
Ha'ken looked at her. He said nothing, waiting, in the way he waited when he'd understood that something was coming and was giving it room to arrive.
Lilith looked at him for a moment.
"I want to tell you something," she said. Her voice was low, not to wake the others.
Ha'ken nodded once.
"I didn't want to say this without confirmation," Lilith said. "I still don't have confirmation. But I've been sitting on it since the ship and I think sitting on it is the wrong choice." She paused. "The figure that appeared. When it came to me on the ship, before the briefing room. It said something it didn't say out loud in front of everyone."
Ha'ken's eyes were steady on her face.
Lilith held his gaze.
"It asked me," she said carefully, "why I carry a fragment of the Emperor's soul."
