They were six hours out from Shatter Mouth, running north with a fair wind, when Lida came to find Elena.
She found her at the chart table, the survey notes from Carvalho spread out alongside the course plot Ortega had laid in. Elena had been staring at the notes long enough that the words had started sliding past her eyes without sticking.
Lida sat in the second chair without asking.
"Osha didn't sleep last night," she said.
Elena looked up.
"The night we arrived at Shatter Mouth. Before the dive." The girl turned the pendant cord between her fingers, the unconscious habit she'd developed. "She was up on deck at midnight. I was going to the head and I saw her. She had a lamp, a small one, and she was at the stern. Holding something in her hand."
"What was she holding?"
"A stone. A river stone — smooth, flat, the kind you find on beaches where there's good current." Lida paused. "Sera showed me what they mean. The cult uses them for navigation markers. A specific arrangement of stones placed in the water marks a location." She paused again. "She dropped it over the side."
The chart table. The survey notes. The grid positions for Grid B. Elena looked at Lida and didn't say anything for a moment.
"Did you tell anyone?"
"I didn't know what it meant until this morning. After the dive. When Sera explained to Carvalho's people about the inversion anchor and what the cult uses to mark locations." Lida's face was careful — the expression of a twelve-year-old who'd made the connection and knew that making it had consequences. "The swimmer who was in the chamber. It was in the collapsed section. Hidden. Waiting."
"The cult knew exactly where we were going to look," Elena said.
"They would have felt the pendant. The counter-resonance would have told them when we arrived and what direction we were working." Lida said it like she was still checking her own logic. "But Osha knew which chamber we were targeting. She was present for the conversation about the fragment's likely location."
"Did Sera—"
"I told her before I came to you. She's—" Lida stopped. "She knew already. She suspected. She said she should have seen it and she didn't." The careful expression again. "She's upset. The quiet kind."
Elena stood.
---
Osha was on the forward deck, working on a length of rope with the steady attention she applied to everything structural. She was a builder — a woman who'd spent her life maintaining an island colony's infrastructure with materials meant for a fraction of the purpose. Her hands knew what to do with rope.
She didn't look up when Elena sat across from her.
"Tell me," Elena said.
Osha's hands kept working. The rope. The quiet.
"How long," she said, "would you like me to talk."
"From the beginning."
Osha set down the rope. She was a middle-aged woman — possibly fifty, possibly older, the island life not exactly kind to faces — with the broad hands of someone who worked with stone and wood, and the specific stillness of someone who'd already decided how much of the truth to say and where to put the rest of it.
"On the island," she said, "the cult has come for as long as any of us remember. Not in force — visitors. Two, three at a time. They never stayed. They watched the barriers. They watched us." She paused. "Nahla forbade contact. But Nahla wasn't everywhere at once. And the cult visitors—" She stopped again. "They were the only outsiders who came. For decades. The only ones."
"They talked to you."
"Not everyone. Some of us." She looked at her hands. "They explained their purpose — not destroying the fragments, not the way you'd explain it to an enemy. The way you'd explain it to people who understood what the Crown had done to a civilization. The drowned kingdom." She paused. "We grew up knowing what the Crown had done. It's in our founding stories. The cult said: we are the guardians. We prevent it from happening again. We destroy the fragments so no one can gather them, because gathered fragments destroy the bearer and eventually destroy everything near the bearer."
"And you believed them."
"I believed that their goal and our goal were the same. We've been keeping the island safe for a hundred years. Keeping the barriers maintained, keeping the volcanic weapon from triggering, keeping anyone from bringing conflicting fragments to the island. The cult was trying to do the same thing on a larger scale." She met Elena's eyes for the first time. "I didn't understand that they destroyed the fragments. I thought they prevented anyone from taking them — protected them from people who'd misuse them. I thought they were guarding."
Elena looked at her. The sincerity of it was visible — not a liar's delivery, not the careful construction of an innocent explanation. Osha had believed this. Had believed the cult's purpose was protection, not destruction. Had not understood, or had not let herself understand, what "prevent anyone from using the fragments" meant in practice.
"The stone marker," Elena said. "What did you tell them."
"The date we were arriving. Our heading. That we were looking for a fragment in the lower ruins." She said it flatly. The accounting, stated without evasion. "I didn't tell them to station someone in the chamber. I didn't tell them to destroy anything. I thought they would—" She stopped.
"You thought they'd prevent me from reaching it."
"Yes." Barely above a breath. "I thought they'd make the water difficult and you'd come back up empty-handed and no one would be hurt. The fragment would still be there, below, waiting. Safe."
Elena looked at her hands on the table. The shards were in her coat pocket. She could feel them through the fabric.
"One of Carvalho's divers is still non-responsive," Elena said. "From the inversion anchor that was placed in the water three days before we arrived. You didn't know about the anchor?"
"No." She held Elena's gaze. "I swear it. I didn't know they'd placed anything. I didn't know about the modified—I didn't know those people existed." A pause. "I knew the cult used Crown-corrupted power. I didn't know they'd done it to themselves."
"The fragment is gone," Elena said. "They destroyed it before I could reach it. That's what they do — that's what they've been doing for centuries. Not protecting. Destroying. The fragments don't go anywhere safe. They stop existing."
Osha looked at her hands. Said nothing.
"The cult told you what they wanted you to believe because they needed information from the island and they couldn't get it any other way. They know exactly who Nahla's Keepers are and exactly what your vulnerabilities are and they've been cultivating your trust for decades for exactly this kind of occasion." Elena kept her voice even. Not angry. The anger was there — she could feel it precisely, the specific fury of a fragment lost and a swimmer in a chamber and three months of cult planning that had used someone's genuine beliefs as its instrument. She kept it exactly where she needed it: behind her, not in front of her. "You made a mistake. A serious one."
"Yes." Barely a whisper.
"You made it because you were told something that aligned with what you already wanted to believe, and you didn't think past it to what the cult's methods actually were." She paused. "That's a human failing. It's also a catastrophic one in this specific context."
Osha said nothing.
"What were you going to do with the pendant information? You're here on the ship. The cult observer was following us — they had our heading. What did the stone add?"
"The depth." Osha looked at her hands. "I knew from Sera's work which chamber was the target. The stone marker's placement told them the specific chamber location." She stopped. "I didn't know that would mean someone waiting in the chamber."
Elena stood. She looked at Osha for a moment — the builder, the woman who'd maintained a dying island's infrastructure with careful dedication for her entire adult life, who'd been given a story about protection and guardian purpose and had accepted it because the alternative was believing that the only outside contact she'd ever had was manipulation.
"You stay on this ship," Elena said. "You don't leave without my knowledge. You answer Sera's questions about what the cult told you — all of it, completely." She paused. "And you don't approach the pendant or any Crown-sensitive equipment on this ship without my permission."
"What happens when we reach Haven?"
Elena looked at her.
"I haven't decided yet," she said.
She went back to the chart table.
Lida was at the doorway. She'd been there for the last part of the exchange — not hiding, just present the way she moved through the ship, which was always quieter than expected. She looked at Elena with the expression of someone who'd been deciding whether to speak.
"The cult visited our island every year," she said. "Sometimes twice. I saw them from the cliffs when I was small." She paused. "I didn't know then what they were. Nahla said they were watchers from the deep sea. I thought that was beautiful." She held Elena's gaze. "I don't think that anymore."
Elena looked at her. "No."
"I want you to know that I would have told you. If I'd seen Osha at the stern that night. I would have told you."
"I know," Elena said.
Lida left.
Old Salt was in the doorway after her. He'd been there for the last few minutes. He didn't say anything. He came in and sat across from Elena and looked at the survey notes.
After a while, he said: "Grid B."
"Yes."
"Two more days. If we go now."
"Port Saro is in five days." She looked at the chart. "If we go to Grid B and there's nothing there — cult already at work, fragment gone, another lost mission — we arrive at Haven the day of the vote with nothing to show and two weeks gone. If we go to Grid B and find the fragment in time—"
"We don't know if it's in time."
"No."
He turned the survey notes over. Read the Grid B data again.
"The cult is moving east," he said. "Carvalho said recent activity at Grid B within the last month." He looked up. "If we don't go now—"
"I know."
She looked north. The direction of Haven. Of Port Saro. Of the two children in a kitchen who had five more days before they expected her back.
She thought about Isi's question, three weeks ago: *Is this yours?* And the answer she'd given. About hard things being yours to do.
This was hers too. Port Saro's council, the political work of keeping seventeen member states from looking for exits, the daily maintenance of a thing that needed constant care to stay alive — that was hers, just as much as the fragment hunt was. You didn't get to choose only the parts that felt like your calling.
Then she looked at the survey notes. At Grid B.
"We stop at the Keepers' island on the way north," she said. "I promised Nahla. It's two days off the direct route. After that—" She paused. "After that I decide."
Old Salt folded the survey notes back the way they'd been.
"I'll tell Ortega about the Keepers' heading," he said.
He went.
Elena looked at the chart table. At the northern heading. At the decisions that were already made and the ones still in progress.
She thought about what Carvalho had said. *If you go to Grid B now, you might get there before them.* The window, closing. The cult moving east at one site per three or four weeks. She had the information. She had the pendant. She had two warships.
What she didn't have was the time to do it right.
Going to Grid B underprepared was how she'd gone to Shatter Mouth. She'd had the tools, she'd cleared the anchor, she'd gotten to the chamber — and a cult swimmer hidden in a wall had been the thing that undid it. Because she hadn't known about the secondary placements. Because she'd assumed that clearing the anchor was enough.
She wouldn't make the same error twice. Grid B required knowing more before arriving, not improvising on site.
She rolled up the chart.
Four weeks. Varro's contacts. Better information.
She went above.
