Norrin had never realised how long less than a mile could be.

On a map, less than a mile was nothing. A neat measurement. A small note in the margin of a survey report. The sort of distance a professor dismissed with one hand while assigning a junior trainee to collect erosion samples from the upper dunes because "you could use the exercise, Mr Norrin."

On bruised ribs, less than a mile became a philosophical objection.

Every step up from the cove argued with him.

The beach fell away behind them in pieces. First the ruined court, all trenches and scattered shells and a sagging net that had died with professional resentment. Then Rika, standing too still in the torn sand with The Ball tucked beneath one arm. Then Freya between the sea and everyone else, small and solid and immovable. Marie hunched over her notebook, trying to write without letting anyone see her hands shake. Lilith at the surf, watching water that had gone back to pretending innocence. Carmella inspecting her sleeve as though the beach itself had committed a social offence.

And the Door.

Still there.

Two steps above the tide line.

Oak. Brass handle. Polished. Impossible.

Waiting.

Norrin looked away before it could notice him looking.

Sylvie walked beside him with her parasol tilted against the sun, moving over broken sand and dune grass as if the path had been laid out for her convenience. She had offered him her arm once. He had refused out of pride, embarrassment, and the deeply mistaken belief that walking under his own power would make him look less fragile.

His ribs had opinions about that.

Several.

Loud ones.

"You are making a very noble expression," Sylvie said.

Norrin focused on not tripping over a root. "Am I?"

"Oh yes. It says, 'I am in tremendous pain, but would rather perish than admit a beautiful woman may have been right.'"

"I do not recall saying that."

"No. Your spine said it for you."

He regretted several things.

Breathing was one of them.

The route climbed through dune grass and patches of broken masonry, old stones half-buried where the jungle had started reclaiming the cove one root at a time. Salt had whitened the edges of the ancient blocks. Shell motifs ran along a collapsed terrace wall to their left, worn almost smooth by centuries of weather.

A narrow drainage channel crossed the path ahead, clogged with leaves, sand, and fresh hoof marks from the pack animals.

Norrin noticed them automatically.

Left-hand donkey. Uneven step. Same one that had tried to bite Coren near the second ridge.

He nearly smiled.

Then his ribs reminded him this was not a smiling activity.

Sylvie's gaze slid toward him.

"You count things when you're frightened."

Norrin stumbled. "I do not."

"You counted the broken steps, the rope scrape on that stone, the three different sets of boot prints, and the place where one of your donkeys considered rebellion."

"That was obvious."

"To you, perhaps."

He glanced at her and immediately wished he had saved the effort for walking.

Sylvie was smiling.

Not teasing now.

Not entirely.

Studying.

That was worse.

"I am trying to make sure we are on the correct route," he said.

"Of course."

"I know the path."

"I know."

"There are several paths through the upper terraces."

"Yes."

"And Professor Tarl's camp is not visible from the beach."

"So I have gathered."

Norrin frowned. "Then why are you smiling?"

"Because you are doing it again."

"Doing what?"

"Being useful while apologising for occupying space."

His foot caught the edge of a half-buried stone.

Sylvie's hand caught his sleeve before he could pitch sideways into a patch of thorny scrub.

Gentle.

Effortless.

Embarrassingly necessary.

Norrin stood very still.

"Thank you," he said.

"You're welcome."

Her hand remained there for one heartbeat longer than it needed to.

Then she let go.

They climbed on.

Behind them, the sound of the sea thinned.

It did not vanish. Not fully. The cove held the surf in its shape, tucked it into stone and air and memory, so that even when the waves were out of sight they still seemed to breathe somewhere behind the world.

Norrin wished that felt comforting.

It did not.

By the time the first proper terrace wall rose through the jungle shade, he had rehearsed seven versions of the warning.

Every single one sounded like heatstroke.

Professor, things came out of the sea.

Professor, I believe the beach is under attack by previously undocumented amphibious hostiles.

Professor, a woman from an impossible inn destroyed a sea creature with a golden ball and then another woman tore a larger one apart with her hands.

Professor, please do not ask follow-up questions until everyone is farther from the coast.

He pressed a hand lightly to his side and tried not to wince.

Sylvie, unfortunately, looked as though she knew all of them.

"Lead with the danger," she said.

"I was going to."

"Not the Door."

"I was not going to mention the Door."

"Not the Maids."

"I was definitely not going to mention the Maids."

"Not Rika."

Norrin's mouth closed.

Sylvie's smile sharpened.

"Oh?"

"There is no way to explain Rika briefly."

"No," Sylvie said softly. "There really isn't."

The path curved around a wall of carved stone and opened into the recessed upper terrace where Professor Tarl's survey camp had been established.

The camp was still there.

That was the first wrong thing.

After the beach, after the sea-spawn, after Rika tearing the brute apart with her bare hands, some unreasonable part of Norrin had expected disaster to leave visible manners.

Broken tents.

Screaming.

Smoke.

Something obvious enough that no one could argue with him.

Instead, Professor Tarl's survey camp looked almost painfully normal.

Canvas tents crouched beneath stretched shade cloths. Crates sat in labelled rows beside a folding table. Rubbing sheets fluttered from a line strung between two old pillars. Sketch boards leaned against salt-worn stone. Measuring frames lay where Tarl's assistants had left them, carefully aligned, because Professor Tarl believed misaligned equipment indicated moral decline.

A donkey complained from somewhere behind a half-collapsed wall with more conviction than most lecturers.

Beside the supply table, two students were arguing over whether a rope coil had been moved by wind, sabotage, or Coren putting it in the wrong place and developing a theory afterwards.

Coren had the rope in his hands.

This weakened his case.

Miko lounged against a crate with the expression of someone who had been entrusted with responsibility and decided to negotiate.

Tibbs sat cross-legged near the rubbing paper, staring at a salt-worn carving while eating something wrapped in Puerto Salmera market paper. His eyes had the peaceful, unfocused intensity of a man receiving theological instruction from masonry.

Sella was the only one working.

Naturally.

She stood by the ledger table, sleeves rolled, hair tied back, pencil tucked behind one ear, counting sample bags with the grim patience of someone keeping civilisation alive by force.

She looked up first.

Her expression shifted from irritation to alarm.

"Norrin?"

The others followed her gaze.

Miko saw Norrin.

Then Sylvie.

Then Norrin again.

Then Sylvie.

His face slowly arranged itself into betrayal, awe, confusion, and what appeared to be a minor religious crisis.

Coren dropped the rope.

It landed on his foot.

He did not notice.

Norrin lifted one hand. "Listen. Something has happened at the beach."

Miko raised one finger.

"Norrin," he said slowly. "Important question."

"There are things coming out of the sea."

"Yes. Terrible. We will return to that. Who is she?"

Norrin stared at him.

Sylvie, to her credit, said nothing.

Yet.

"That is not the important question," Norrin said.

"It is currently the most visible question."

Coren nodded with grave support. "Very visible."

Sella closed her eyes.

Norrin forced himself not to look at Sylvie.

"There are monsters on the beach."

Miko nodded. "Understood."

"No, you do not understand."

"Sea monsters?"

"Yes."

"Actual monsters?"

"Yes."

"From the sea?"

"Yes."

Miko pointed past Norrin with both hands. "And her?"

Norrin inhaled carefully.

Pain objected.

"Her name is Sylvie. She helped me get here. That is all you need to know."

"That is absolutely not all we need to know," Coren said.

Tibbs lifted one vague hand without looking away from the carving.

"The sea is upstairs."

Everyone ignored him.

Norrin did not.

Sylvie did not either.

Miko waved a hand near Tibbs' face. "You are not helping."

Tibbs chewed slowly.

"The stone said it first."

"The stone did not say anything."

"Not to you."

Sella slapped the ledger shut with enough force to startle the donkey.

"Miko. Coren. Stop interrogating the injured person about the woman standing beside him."

Miko looked wounded. "Sella, be reasonable."

"I am the only person here being reasonable."

"That is your opinion."

"That is the ledger's opinion."

"The ledger doesn't have opinions."

"It does when I hold it."

Miko reconsidered.

Norrin tried to step forward and immediately regretted it. His side tightened. His breath caught. He managed not to fold, but only because Sylvie's hand appeared lightly beneath his elbow.

Sella saw that.

Her eyes narrowed.

Not at Sylvie.

At Norrin.

"You're standing very close to her."

Norrin blinked. "There are circumstances."

"You're not panicking."

"I am absolutely panicking."

"Not properly."

That silenced him.

Miko's head whipped toward him. "Wait. She's right. You're not dying."

"I am in significant pain."

"That's different. Around women, you usually become furniture with a pulse."

Coren nodded. "Or a lamp."

"A lamp?"

"A nervous lamp."

Norrin pressed his free hand over his face.

Sylvie made a soft, interested sound.

"Oh," she murmured. "How revealing."

"It is not revealing," Norrin said through his fingers.

"It is a little revealing," Sella said.

"That is not helping."

"Good," Miko said, pointing at Sella. "Now that we've established Norrin has somehow returned from the beach with an impossibly beautiful woman and partial social function, we return to the important question."

"Monsters," Norrin said.

"After that."

"There is no after that."

Miko clasped both hands together and leaned forward. "Who is she?"

Sylvie's parasol stopped turning.

The change was tiny.

Norrin felt it anyway.

Until that moment, she had allowed the scene to happen around her. She had stood slightly behind him, amused and watchful, letting him speak, letting his world reveal itself in all its ridiculous student-shaped glory.

Now her smile changed.

Not larger.

Sharper.

"Oh," she said softly. "So this is how you do it."

Miko blinked. "Do what?"

"Make him smaller before he has finished speaking."

The camp went quiet in a way it had not managed for sea monsters.

Norrin went very still.

Sylvie stepped closer and brushed a careful line of sand from his sleeve. It was not intimate enough to mean anything.

It was exactly intimate enough to destroy several young men.

"Poor darling," she said, voice warm as honey and twice as dangerous. "You did warn me they were difficult."

Miko and Coren made two different sounds of spiritual collapse.

Coren grabbed Miko's shoulder.

Miko grabbed Coren's shirt.

Tibbs looked up at last, studied them both, and whispered, "The quiet ones ascend first."

Norrin's brain attempted to escape through the back of his skull.

"They are not my—" he began.

Sylvie's hand settled lightly on his arm.

"Hush. You're injured."

Miko clutched at his chest.

"Darling," he repeated.

Coren stared at Norrin as though seeing him for the first time and not enjoying the discovery. "When did this happen?"

"It did not happen."

"It clearly happened."

"It did not clearly happen."

Sylvie tilted her head against Norrin's shoulder by the barest fraction.

"It is sweet that you're shy."

"I am not shy. I am trying to prevent people dying."

"That too."

Sella stared at Sylvie.

Then at Norrin.

Then at Miko and Coren, who were now somewhere between betrayal and worship.

Then she made the exhausted sound of someone who had just watched order slip down a drain and decided the drain deserved it.

"Enough."

The word cut through the camp.

Miko froze.

Coren froze.

Tibbs slowly raised both hands, though no one had accused him of anything specific.

Sella pointed at Norrin.

"He is bleeding."

Norrin glanced down.

"I am mostly scraped."

"He is bruised, scraped, sunstruck, and standing beside a woman none of us can explain. He is also Norrin, which means if he says he saw something impossible, he probably spent the first five minutes trying to disprove himself before coming here."

Norrin looked at her.

Sella did not soften.

That was not her style.

But her voice changed slightly.

"So maybe listen."

Miko's expression shifted.

Not completely serious.

But less useless.

Coren looked down at the rope on his foot, as though discovering gravity had continued in his absence.

Norrin swallowed.

"Things came out of the sea," he said, slower this time. "Pale creatures. Webbed hands. Reef growths. Blue veins. They attacked the beach. There were many of them, then one larger one. Much larger. It struck Rika down."

Miko opened his mouth.

Sella pointed at him without looking.

He closed it.

Norrin continued.

"The beach is not safe. The sea is not safe. Professor Tarl needs to bring everyone back from the inner temple, or at least move away from the coastal side of the ruins until we understand what happened."

Sella's jaw tightened.

"Professor Tarl isn't here."

The words landed wrong.

Norrin turned fully toward her.

"What?"

"He took the inner temple group through the western arch after the second bell."

Norrin's hand tightened against his side.

Sylvie's gaze moved from Sella to him.

Watching.

Waiting.

"Elira went with them," Sella said.

The pain in Norrin's ribs became distant.

Only for a heartbeat.

Only long enough for his face to go still and his fingers to curl into the torn fabric at his side.

But Sylvie saw it.

Of course she saw it.

Her parasol tilted.

"Elira," she said softly, tasting the name like a question.

Norrin was already looking toward the route that climbed deeper through the terraces.

"She's with Professor Tarl?"

Sella nodded. "She was assigned to the rubbing frames. Professor wanted the inner wall copied before the afternoon heat got worse."

Norrin had not spoken properly to Elira in weeks.

Not really.

They had exchanged field notes, shared water, argued over shell classifications, and once spent an entire dinner not mentioning the fact that childhood friendships became awkward when both people grew into different shapes.

They had grown up close enough that she still knew when he was lying, which was unfortunate because he was terrible at it. Then lectures, assignments, pride, embarrassment, other friends, and the quiet machinery of becoming adults had moved them into different orbits.

They still talked.

Sometimes.

Carefully.

But she was still Elira.

And she was still down there.

Miko rubbed the back of his neck. "They should be fine, right? I mean, the inner temple is up here. The sea's down there."

Tibbs looked up from his market-wrapped something.

"The sea is upstairs," he said again.

This time, no one laughed immediately.

Norrin looked at him.

"What do you mean?"

Tibbs considered the question with terrible sincerity.

"The arch changed."

Coren groaned. "The arch did not change."

"It did."

"You ate half of whatever that was before noon."

"It was medicinal."

"You were not ill."

Tibbs stared at the stone carving.

"Not in the part that matters."

Sella's expression sharpened despite herself.

"What changed?"

Tibbs lifted one hand and pointed vaguely toward the path.

"It was less open before."

Miko stared at him.

"That is not a useful sentence."

"It will be."

Sylvie smiled.

Not brightly.

Not playfully.

With interest.

Norrin did not like that at all.

Sella moved around the table and grabbed a folded route sheet from beneath a stone weight. She handed it to Norrin, then seemed to remember his hands were not steady and gave it to Sylvie instead.

"Western arch route. Main terrace, left of the old cistern, then down past the shell pillars. The inner chamber is marked. If Professor Tarl hasn't moved them again, they'll be there."

"Has anything else happened?" Norrin asked.

Sella hesitated.

That frightened him more than a quick answer.

"We heard noise from the coast," she said. "Booms. Tremors. Professor said the headland does that when the tide shifts."

"The headland does not do that."

"I know."

Miko looked between them. "You know?"

Sella's mouth tightened. "I know Professor Tarl says that when he doesn't want to stop work."

That sounded far too true.

Norrin took a step toward the route.

Sylvie's fingers brushed the edge of his sleeve.

Not stopping him.

Only reminding him that his body was still attached.

"You are injured," she said.

"Elira is there."

There was no argument in his voice.

Only fact.

Sylvie watched him for a moment.

Then her smile returned, smaller and much less amused.

"Then we should hurry."

Miko straightened. "We should come."

Sella looked at him.

"You should stay here and do the job you were left to do."

"I can help."

"You dropped a rope on your own foot and did not notice for nearly four minutes."

Coren looked down again.

"Oh."

Miko pointed at Tibbs. "Then Tibbs can—"

"No," Sella said.

Tibbs nodded solemnly. "I am watching the upstairs sea."

"Exactly why you are staying here."

Norrin looked at Sella. "If we are not back soon—"

"I know."

She did.

That was why she had been the only one working.

She looked past him toward Sylvie.

"I don't know who you are."

Sylvie gave her a small curtsy. "How refreshing."

Sella did not blink.

"But he came back with you. And he's standing. So for the moment, that is enough."

Sylvie's expression softened by one almost invisible degree.

"Practical girl."

"Someone has to be."

Miko leaned toward Coren and whispered, far too loudly, "Did she just approve of Sella too?"

Coren whispered back, "I think we are all being measured."

Tibbs raised one biscuit. "She is measuring the stairs inside people."

No one knew what to do with that.

Norrin started toward the western route.

His side burned.

His legs felt untrustworthy.

His head still rang faintly with the sound of Rika shouting his name.

But Elira was with Professor Tarl.

And Professor Tarl would not listen unless the warning arrived wearing enough evidence to satisfy his pride.

Norrin had no evidence.

Only pain.

Only fear.

Only the memory of the sea growing hands.

Sylvie stepped beside him, parasol balanced lightly against her shoulder.

Behind them, Tibbs spoke softly to no one in particular.

"Don't go through the open mouth."

Miko sighed. "It is an arch."

Tibbs looked genuinely saddened by this failure of imagination.

"For now."

Norrin did not look back.

Neither did Sylvie.

The route to the inner temple began politely enough.

That was how old ruins worked, Norrin had learned. They never announced the dangerous part properly. They started with sunlit stone, familiar steps, survey chalk, and enough broken masonry to make everything feel academically respectable.

Then, once everyone had relaxed, they remembered the teeth.

He followed the terrace path with Sylvie at his side, Sella's folded route sheet held loosely in her gloved hand. The path climbed left of the old cistern, just as Sella had said, past a low wall where shell-shaped reliefs had been worn nearly smooth by time and weather. Rope markers from the expedition had been tied around three leaning stones, their red cloth strips fluttering weakly in the humid air.

Norrin counted them without meaning to.

One.

Two.

Three.

Still in place.

That helped.

A little.

The camp sounds faded behind them. Miko and Coren's voices became distant fragments, then vanished beneath the rustle of jungle leaves and the soft scrape of Norrin's boots against ancient stone.

Tibbs' last warning did not vanish.

Don't go through the open mouth.

Norrin wished very much that it had.

Sylvie turned the route sheet once, then twice, then folded it closed.

"You know the way," she said.

"I know the upper terraces," Norrin replied. "Not the inner temple."

"And yet your feet have opinions."

"My feet are mostly arguing with my ribs."

"Your ribs are very talkative."

"They have had a difficult morning."

"So have you."

He glanced at her.

Sylvie's parasol tilted just enough to shade her eyes.

There was humour in her voice still, but less of it than before. Her gaze had shifted from him to the stones ahead, then to the carved gutter running along the edge of the path, then to the faint white crust gathered in the cracks.

Norrin saw it too.

Salt.

That was not unusual. Not here. The entire ruin had been at war with salt for centuries. It whitened exposed stone, gathered in old joints, flaked the edges of carvings, and made Professor Tarl talk at length about erosion patterns until even the donkeys looked spiritually diminished.

But this salt looked fresh.

Fine white crystals clung to the gutter like frost.

Norrin slowed.

Sylvie slowed with him.

Neither of them spoke.

A lizard darted across a sun-warmed block and vanished beneath a curtain of roots. Far above, the cliff-head temple rose in broken tiers, its upper stones catching the afternoon glare. From the beach, it had looked distant and almost decorative. Up here, beneath the terraces, it felt less like a ruin and more like something that had been waiting under a blanket of jungle for someone foolish enough to lift the edge.

The path narrowed.

The air cooled.

Not kindly.

Damply.

It pressed against Norrin's skin with the heavy patience of a cellar that had remembered the ocean.

He stopped beside the old cistern.

The stone rim was cracked and half-swallowed by vines, its interior dark beneath a lattice of roots and fallen leaves. Earlier that morning, it had smelled of damp earth and old rainwater.

Now it smelled faintly of tide pools.

Norrin's throat tightened.

"That's new," he said.

Sylvie smiled.

Not happily.

"I wondered if you would notice."

"You noticed first."

"Naturally."

"Is that meant to comfort me?"

"Not especially."

She stepped closer to the cistern and leaned over the edge without touching it. Her pale-lavender hair fell forward in a soft cascade, though not a single strand crossed the boundary of the darkness below. For a moment she looked like a woman listening at a door.

Then her head tipped slightly.

"Oh," she murmured.

Norrin's fingers tightened around the emergency biscuit Marie had pressed into his hand.

He had forgotten he was still holding it.

"Oh is not ideal."

"That depends."

"On what?"

"On whether it is saying hello."

The darkness inside the cistern gave one small, wet drip.

Norrin took a step back.

Sylvie straightened, eyes bright with interest.

"Don't touch anything," he said.

Her expression became wounded. "You make one or two assumptions about a girl."

"I have known you for less than a day and every assumption has been self-defence."

"How quickly you learn."

She turned away from the cistern, but her gaze kept moving.

Over the old drainage channels.

Along the carved shell borders.

Past the faded figures marching along the terrace wall, their long arms raised toward a stylised sea.

Most of the reliefs were damaged. Salt had eaten their faces. Vines had cracked their limbs. Moss had softened once-sharp lines into gentle ruin.

But one carving near the base of the wall looked different.

Not new.

Worse.

Remembered.

The figure had a human body, or something pretending to have one, bowed beneath a crown of curling limbs. Waves rose around its feet. Its mouth was open.

Norrin frowned.

"That wasn't as clear before."

Sylvie stopped walking.

The world seemed to notice.

"What wasn't?" she asked softly.

"That carving." He pointed. "I made a sketch of this section two days ago. That one was almost gone. The lower half was worn smooth."

"And now?"

Norrin swallowed.

The figure's open mouth stared from the stone.

"Now it has teeth."

Sylvie's smile returned.

Small.

Sharp.

Curious in the way a knife might be curious about skin.

She crossed to the wall and crouched before the carving. Not close enough to touch. Not yet. Her parasol rested against her shoulder, the tip hovering above the stone.

"That one is pretending," she said.

Norrin stared at her.

"Pretending what?"

"To be carved."

A chill moved through him that had nothing to do with shade.

The path ahead disappeared beneath a hanging veil of vines. Beyond it stood the western arch.

It had always been the western arch. That was what Professor Tarl called it, because Professor Tarl believed naming things accurately was one of the few defences civilisation had against nonsense.

Norrin had copied its dimensions yesterday.

Fourteen feet high.

Nine feet wide.

Outer curve damaged.

Left support cracked.

Wave-glyphs along the lintel, mostly decorative.

Now, standing before it, Norrin understood why Tibbs had called it an open mouth.

The arch was not shaped differently.

Probably.

But the vines hanging from its upper stones looked too much like wet hair. The shadow beneath it sat too dark against the daylight. The lower carvings, half-buried in moss and salt, seemed to curve inward instead of out, drawing the eye toward the passage beyond.

Norrin tried to breathe shallowly.

His ribs punished even that.

Sylvie stood beside him.

For once, she did not tease.

"That," she said, "is rude."

"The arch?"

"The invitation."

Norrin looked at her. "Please do not call it an invitation."

"It is one."

"That is worse."

"Yes."

Her parasol tip lifted.

Norrin caught the motion and went very still.

"Sylvie."

She glanced at him.

There was delight in her eyes.

Not careless delight. Not stupid delight. Something older and stranger than that. The look of someone who had found a locked box humming to itself and had never once in her life believed locked boxes deserved privacy.

"No," Norrin said.

"I have not done anything."

"You are visibly considering it."

"I am admiring the workmanship."

"You are admiring the suspicious magical archway that a stoned man described as an open mouth."

"An unfair summary."

"An accurate one."

She smiled at the stone.

The carved wave-eye on the lower left support stared back.

At least, it seemed to.

Sylvie leaned in and tapped the arch once with the very tip of her closed parasol.

Not hard.

Not dramatically.

A tiny sound.

Stone against parasol.

Click.

Light moved beneath the rune.

Only for an instant.

Blue-green, thin as a vein beneath skin.

Norrin felt it in his teeth.

Then it was gone.

The arch was stone again.

Old.

Silent.

Harmless, in the way cliffs were harmless until one stood underneath them at the wrong moment.

Sylvie's smile widened.

"Well," she said softly. "That is impolite."

Norrin stared at the rune. "You touched it."

"I introduced myself."

"It answered."

"Exactly."

"That should not make you pleased."

"It would be rude not to appreciate a response."

From somewhere beyond the arch, Professor Tarl's voice echoed through the stone.

"…not devotional panic, Miss Venn. Documentation. If we allow every fragment of local superstition to dictate interpretation, we may as well return to Puerto Salmera and ask the market vendors to date the masonry by gossip."

Norrin went cold.

Sylvie's smile sharpened.

"Ah," she said. "There he is."
