Sylas arrived on a Friday with someone else's blood on his collar and the look of a man who had recently made a poor decision and was now fully committed to the consequences.
He sat at the counter. He did not order anything. He put his elbows on the surface and said, "Where is Vane?"
"Out." Ro set a coffee in front of him anyway. He'd drink it; she'd learned that much. "What happened?"
"I had a conversation." He picked up the coffee. "With a member of the cult's inner circle. It was — direct."
"Whose blood?"
"Theirs." He drank. "I was careful. They will not die." A pause. "Probably."
She thought about saying something about that. Decided it wasn't the moment. "What did they tell you?"
He set down the cup and looked at her with that specific Sylas expression — the one that said he was about to tell her something he'd been sitting on, working out the angle of, deciding whether the telling helped or hurt his position. Sylas always had a position.
"You know the cult wants the barriers down," he said.
"I know." Elias. Three nights ago.
He blinked. Just slightly. "You already—"
"Yes. What don't I know?"
A pause. He reassessed. She watched him do it.
"They have a mechanism," he said. "It is not theoretical. They are not simply — wishing at the problem. They have identified a method, and they have been implementing it for the past two years." He turned the coffee cup. "The weakening eastern boundary markers. The cult is not observing that. They are causing it."
Ro kept her expression level. The hum in her chest shifted.
"There is a sequence," Sylas said. "Seven anchors. But they do not all need to be removed — the system has redundancies. What you need, to cause cascade failure, is to corrupt the keystone and two of the six secondary anchors." He looked at her. "The eastern markers are one secondary anchor. It has been under targeted interference for approximately eighteen months. Slow. Careful. Below the threshold at which most Court watchers would flag it as intentional."
"They're patient," she said.
"Extraordinarily." He leaned forward slightly. "The second secondary anchor is in Brixton. The interference there began only recently — three weeks ago. They accelerated after the Recognition. After Miriam died and the binding transferred unexpectedly." His jaw was tight. "They did not plan for you."
"What did they plan for?"
"A death, likely. The binding without a successor, forced to attach to whatever was nearest — or not attach at all. A weakened keystone held by something unsuitable." He paused. "You were a variable they did not account for. You are resistant to their interference in ways they did not anticipate."
The immunity. What Elias had called being touched.
"They know about it now," she said.
"Yes." He drank the rest of his coffee. "They are adapting their strategy. What I took from the conversation tonight is that they have a timeline. The eastern markers — they estimate another six to eight weeks before that secondary anchor is sufficiently corrupted. Brixton will take longer. Three months, perhaps four."
"So worst-case five months."
"If they do not accelerate."
"And if they get the keystoned corrupted first—"
"The other failures compound faster. Yes." He set down the cup with a small hard sound. "I want you to understand what this means, in practical terms. The barriers between the fae world and the human world in London do not simply — dissolve and then everything is fine and humans and fae coexist. The barriers dissolve and the accumulated pressure of centuries of separation releases at once."
She thought about what Elias had said. Two ecosystems, the fence removed.
"It would be catastrophic," she said.
"For everyone. Fae included. Many fae do not want this. Many fae would lose everything they have built here — their structures, their territories, the careful arrangements of centuries." He looked at her directly. "Which is why I am here."
Not for you, his tone said. Not for the sentimental reasons. He was here because he had something to lose.
She respected that more than she would have respected a more palatable motivation.
"Caelan needs to hear this," she said.
"I imagine he already suspects most of it." Sylas said it with the particular dryness of someone who had complicated feelings about Caelan Vane's information gathering capabilities.
"Suspecting and knowing are different. We need to know." She pulled out her phone. "I'm going to call him in."
"He will have opinions about the timeline," Sylas said. "He will want to move faster than is wise."
"You two have different definitions of wise."
"We have different risk tolerances." He looked at his hands. "Vane has been managing this boundary for sixty years. He will feel it as a personal failure. That will affect his judgment."
Ro paused. Looked at Sylas. "Is that a warning?"
"It is an observation." He met her eyes. "You are the anchor. Not him. The decisions about how to manage this should ultimately be yours."
She thought about that for a moment. About the weight of it. About Ada's letter and Miriam's ledger and the generations of Blackwood women who'd sat on this side of this counter and managed things they hadn't been adequately prepared for.
She called Caelan.
He answered on the second ring. She said: "Get here. Sylas has a timeline. It's worse than we thought."
A pause. Long enough to be almost nothing.
"I will be there in four minutes," he said.
She hung up. Set the phone face-down on the counter. Outside, Friday night London was beginning its transformation — the shift from the tail end of the working day to the beginning of the weekend, the drinkers starting to move, the specific quality of noise changing.
"The diner," she said. "While we protect the keystone. The diner needs to keep running."
Sylas looked at her as if she'd said something slightly absurd.
"Yes," she said. "I know. But if the Hollow Crown closes, if it looks like the anchor is in crisis, every fae in London feels that. The Courts will panic. The cult will know they're succeeding." She looked at the taped window, the familiar scratched counter, the coffee machine that needed descaling, the fluorescent light that still buzzed. "This diner stays open. Normal hours. Whatever we're doing about the boundary markers, we do it around that."
Sylas stared at her for a long moment.
"You are," he said carefully, "a very specific kind of unusual."
"Art history dropout," she said. "We develop coping mechanisms."
The door opened. Caelan came in fast, coat still moving from his speed, eyes already tracking — Sylas, Ro, the space, assessing. His knuckles were white at his sides. He'd been somewhere that involved being alert, she could read it in him now. Four minutes. She believed exactly four minutes.
He looked at Sylas with an expression that was not quite hostility and not quite trust and was something that had been compressed by a very long acquaintance into a kind of grim pragmatism.
"Tell me," he said.
Sylas told him. All of it.
And Ro watched Caelan's face while he heard the timeline. Watched the thing Sylas had predicted — the particular tightening around his eyes, the way his jaw set, the controlled quality becoming more controlled and therefore more visible. Sixty years. He had been managing this for sixty years and it was coming apart on a five-month clock.
When Sylas finished, there was silence.
Then Caelan said, very precisely: "We cannot address this defensively. Protecting the anchor while the secondary markers degrade is not a solution. We need to find where they are conducting the interference and stop it at the source."
"Agreed," Ro said.
He looked at her. Something in his expression shifted — the tightening softened, just slightly, at the fact that she hadn't argued.
"Shoreditch first," she said. "Elias gave me an address. We go, we look, and we do not start anything we cannot finish." She looked at both of them. "Agreed?"
"Agreed," Sylas said, with the tone of someone who didn't entirely mean it but would hold to it anyway.
Caelan looked at her for a long moment. Those grey eyes, the exact colour of sky before rain. Three hundred years of bad decisions and good ones and survival. Something she didn't have a word for, moving in them.
"Agreed," he said. "Ro."
Always her name. Always that careful emphasis, like he was reminding both of them that she was here. Real. In this with him.
She picked up the coffee pot.
"Right," she said. "Sit down, both of you. If we're planning something, we're planning it properly, and I am not doing it on empty stomachs." She paused. "Yours can't be empty in the same way mine is, I know. But you know what I mean."
Sylas looked at Caelan. Caelan looked at Sylas.
Some kind of long-standing, deeply unenthusiastic communication passed between them.
They both sat down.
Outside, London went on being London. The taped crack in the window caught the streetlight and fractured it into small pieces. Somewhere east of the diner, in the specific dark of Shoreditch, something was quietly eating through the fabric of things, patient as rot.
But not yet finished.
Not yet.
