Carvalho's team surfaced an hour later.
They'd retrieved three crates of artifacts from the upper chambers — historical materials, architectural records, the accumulated debris of a significant civic building from a civilization three centuries dead. Carvalho himself came aboard the *Resolution* to discuss what his team had found, which was not what Elena had expected. She'd expected him to collect his crates, wave, and go north.
Instead he stood at the stern rail looking at the shards in Elena's palm with an expression she couldn't entirely read.
"The thing that came out of the collapsed wall," he said. "My team saw it on the way up. Passing through the ruins at depth."
"Yes."
"What is it."
"A person who was modified by the cult's use of corrupted Crown resonance. The modifications allow extended underwater operation." She looked at the shards. "There are probably more of them in the surrounding waters. The one in the chamber was there specifically to destroy the fragment. The others may be guards or observers."
He processed this. "How many?"
"I don't know. The blockade attack used four large constructs. The underwater operatives are different — smaller scale, more targeted." She closed her fist. "Your non-responsive diver from yesterday."
"Still non-responsive."
"What I said last night still stands. The surgeon can help if—"
"She's already improved. Your surgeon has been aboard since last night." He paused. "I didn't expect that."
"I know."
He looked at the shards. "The fragment is gone."
"Yes."
"The cult destroyed it."
"That's their purpose. Not to possess the fragments — to ensure they can't be reassembled." She met his eyes. "They've been doing this for centuries. Every Crown fragment they can reach, they've been destroying or guarding against recovery. Not out of malice. Out of what they believe is necessity."
Carvalho was quiet for a moment. "You sound like you almost agree with them."
"I understand their reasoning. That's not the same thing." She looked at the water. At the site beneath them. "Your survey — three months at this coast. You've identified other locations."
He went still.
"Not just Shatter Mouth," she said. "The hawk recovery authority covered the full Southern coast. You've been mapping Crown sites."
"I'm not authorized to share survey intelligence with—"
"With the Federation." She nodded. "I know. But let me tell you something about the other sites on your survey, Lt. Commander." She looked at him. "The cult has already found them. Not all of them — probably the ones closer to their territory, the ones with stronger resonance. They'll work outward from those. Every site you've mapped, they'll eventually reach. They'll station modified operatives in the underwater approaches. They'll place inversion anchors." She paused. "And then the Imperial recovery teams who go to those sites will encounter what your divers encountered here. The anchor, the operatives, the specific way they ensure you can't access what's below."
He watched her. The careful attention of someone hearing something that was true and didn't want to be.
"The cult doesn't distinguish between the Empire and the Federation," she said. "They'll destroy the fragment before you can take it as readily as they destroyed it before I could." She held his gaze. "Two sites. That's all I'm asking. The two locations your survey identified as highest probability for fragment presence. Give me the grid positions and the survey notes and I'll take my people there before the cult does. If we find fragments, I have them. If the cult gets there first, no one has them." She paused. "Option three is you go to those sites with an Imperial recovery team and end up where you ended up here."
It was a harder argument than it looked. She'd structured it so that giving her the survey data was defensible in an Imperial after-action review — not because she'd asked for it, but because sharing it was better than watching the cult destroy the sites.
Carvalho knew it too. He stood at the rail and didn't say anything for long enough that Old Salt, behind Elena's shoulder, began the slow tactical shift of weight that meant he was getting ready for the conversation to turn.
"Two sites," Carvalho said. "Not all of them."
"Two."
He looked at the water. "The sites with the strongest fragment resonance signatures, according to our survey instruments."
"Yes."
Another pause. He reached into his coat and withdrew a folded paper. He didn't hand it to her yet.
"I need something from you," he said. "Not for me. For my non-responsive diver. Your surgeon has helped, but she needs information she doesn't have — specifically about what the inversion anchor does to Crown-sensitive people and how the effects persist." He looked at Elena. "I'm told your specialist on Crown matters is better informed than anyone."
Elena turned. "Sera."
The old woman was sitting on a coil of rope near the mainmast, the pendant in her lap, Lida beside her. She'd been resting since dawn, visibly diminished, the tremor in her hands present even at rest. But her head had come up the moment Elena said her name.
"The diver," Elena said. "Carvalho's surgeon needs what you know about inversion anchor exposure. Will you?"
"Yes." She started to stand.
Lida was on her feet first, arm out, letting Sera use her as a brace without being instructed. The two of them crossed to the stern rail together.
Carvalho watched Sera approach. He had the paper still in his hand.
Sera stopped in front of him. Tilted her head slightly — the way she oriented to voices she'd just heard. "The diver who was in the water during the anchor's peak resonance?"
"Yes."
"Tell me what she's presenting. I'll tell your surgeon what I know."
He described the symptoms. Sera listened without interrupting and then spoke for five minutes in the precise technical voice she used when she was giving information she'd verified. Carvalho translated some of it in real time for what was clearly a surgeon's briefing in his memory.
When Sera finished, he held out the paper.
Elena took it.
Two grid positions. Detailed survey notes — depth profiles, resonance signatures, structural assessments of the underwater ruins. His three-month survey compressed into two pages of dense notation that told her more about the Southern coast's fragment sites than she'd known an hour ago.
"The positions are accurate," he said. "The resonance signatures are the best our instruments can produce." He paused. "For whatever it's worth — the cult knows about those sites too. We found evidence of previous underwater activity at both of them."
"How recent?"
"The most recent was within the last month. At the second site — the eastern one." He looked at her. "They're working the sites in a pattern. Moving east from their territory."
"Which site is furthest east?"
"Grid B on that paper. That's the second column."
She looked at Grid B. East of Shatter Mouth, east of the cult's established territory from what she knew of it. They were expanding their reach. Moving faster than she'd assumed.
"If you go to Grid B now," Carvalho said, "you might get there before them."
"Or they might already be there."
"Yes." He straightened. "I'll give your surgeon's work the credit it deserves in my report. I'll also note that you cooperated in clearing a cult inversion anchor from the dive site and that the cooperation was conducted at arms' length and addressed a tactical problem we couldn't resolve independently." He looked at her. "That's the version that ends up in the hawk council's files."
"And the fragment."
"The fragment was destroyed by cult intervention before it could be recovered by any party." He kept her gaze. "Which is true."
She held his eyes. He was a hawk officer. He'd been trained by the same system that produced Rossa, that ran the blockade, that had sent her people into a dead zone to be killed by cult constructs. He was also a professional who'd watched four of his divers get hurt and had a non-responsive woman on his ship and had done the calculation that getting her better was worth sharing survey data with the enemy.
People were complicated. She'd spent twenty years knowing that and still occasionally being surprised by it.
She also knew she could have pushed for all the survey sites instead of just two. He'd given because the argument was correct, and because the diver, and because Sera. If she'd pushed for the complete survey, he might have given it. She'd judged that two was enough and that pushing for everything risked poisoning what they'd built in the last twenty-four hours. The moderate outcome was the right outcome. Not everything you could get was everything you should take.
"Safe passage north," she said. It wasn't a threat and he knew it wasn't, but saying it put something official in the space between them.
"Same to you." He went over the side into his dinghy.
---
By noon, the Imperial frigate was a sail on the northern horizon. Gone north with its crates and its recovering diver and whatever Carvalho was going to file in his report.
She hoped the diver recovered fully. Not for strategic reasons — just the ordinary human preference that the people Sera had helped would be all right.
Old Salt read the survey notes over Elena's shoulder. He didn't say anything for a long time.
Then: "Grid B. Eastern site. How long to reach it from here?"
"Two days. Maybe three if the current's against us."
He looked at the shards on the chart table. She'd laid them out — the seven pieces, the largest about the size of her thumbnail, no single piece keeping any of the original resonance. Dead fragments. The thing that had been approaching in the chamber was gone.
"We can still go," he said. "We've lost two days and a fragment, but we haven't lost the expedition."
She looked at the shards.
"The Port Saro vote," she said. "Seven days from the dispatch. We've been here two days."
"Five days left." He did the arithmetic she'd already done. "Grid B would take four days round-trip, minimum. We'd arrive at Haven the day of the vote. Maybe after."
She swept the shards off the chart table into her hand. Closed her fingers around them.
"Signal the *Sovereign*," she said. "North-northeast. We'll discuss Grid B on the way home."
Old Salt went to signal the *Sovereign*. Elena stood at the chart table with the shards in her closed fist and looked at the northern heading for a moment.
Then she put the shards in her coat pocket, beside Kira's letter from two days ago, beside the survey notes Carvalho had given her. The weight of several possible futures, all of them requiring her to be somewhere other than where she was.
She went on deck.
The *Sovereign* was already coming about. Ortega was giving orders. The *Resolution* swung north.
On the stern rail, Osha stood looking back at Shatter Mouth as the distance opened between the ship and the site. Just standing. Not hiding from Elena's gaze, not avoiding it — just standing and looking at the thing she'd helped cause, in the way people stood when the accounting was still in progress.
Elena watched her for a moment. Then looked north.
Ahead: Haven. Port Saro's vote. The diplomacy that needed a military position she didn't currently have.
In her pocket: two coordinates that might contain what she needed.
Both of them requiring more time than she could spare right now.
She thought about Carvalho sailing north with his crates of artifacts and his two pages of survey notes given away and his recovering diver and whatever he was going to put in his report. He'd done a professional thing in an unprofessional situation and had gotten something useful from it. She respected that more than she wanted to.
That was the situation. She'd held worse hands.
