Between Tides

Summary:

A royal command. A luxury liner. A sea that does not forget.

Duchess [y/f/n] [y/l/n] is sent aboard the Campania with Ciel Phantomhive, Sebastian Michaelis, and her own demon butler, Dorian. Their task is simple in name only: investigate a society that refuses to accept death. On open water there is nowhere to run when the line between duty, desire, and the grave begins to blur.

Out at sea there are no safe corridors, only locked cabins, polished railings, and the thin metal skin between the living and what waits below. Between tides, loyalty, obsession, and old bargains begin to shift.

Chapter 1: The Sea that Swallows Names

Summary:

The Duchess boards the Campania beside Ciel, Sebastian, and Dorian, navigating brittle courtesies with the Midfords as the ship pulls away from London. Fog closes in, the sea stretches open, and a familiar, unwelcome presence slips quietly aboard.

Chapter Text

“Every voyage begins with a name. Every disaster ends without one.”

~Your POV~

The harbor smelled of iron, salt, and steam, the scent of something too restless to stay still.

We arrived just as the morning fog began to thin, revealing the Campania in full. Its hull gleamed like a promise, every brass detail reflecting the pale morning light. The crowd around us swelled and murmured, drawn toward the spectacle of it. Laughter tangled with the cries of gulls and the steady hiss of steam from the boilers. Somewhere nearby, a whistle blew, long and sharp, like a warning to those still deciding whether to board.

The docks stretched wide, a forest of masts and cranes silhouetted against the awakening sky. Men in dark coats carried luggage and shouted orders, their boots echoing on wet planks. Perfume and coal smoke drifted together in strange harmony, the city’s heartbeat pressed against the sea. A row of lifeboats hung neat and white along the upper deck, paint unscuffed, ropes clean and proud. Flags snapped high above us, bright bits of color against the washed out sky, as if the ship wanted to be seen from as far as possible.

This voyage was meant to be a symbol of progress, of human triumph. Standing there, it felt like theater. The kind built to convince the audience the actors were gods, and that the sea would politely applaud instead of swallow.

Ciel stepped down from the carriage first. Sebastian was already beside him, one gloved hand steadying him with the precision of ritual. They moved together with the symmetry of habit, command and obedience polished into grace. I followed, skirts whispering against the damp boards, the faint tack of my heels against the wood lost beneath the harbor noise. The air tasted faintly of coal and brine.

Dorian stood just behind me, hands folded at his back, the faint glint of sunlight catching in his auburn hair. People glanced his way without meaning to, the kind of double take one gives a face the world was not built to explain. Some of them frowned as if they had forgotten something important. Others stared a heartbeat too long, then looked away, unsettled by an awe they could not name.

"Too much spectacle," Dorian murmured, voice pitched low for me alone. "Humans build their monuments tall when they need to feel small."

I almost smiled. "And when do demons build them?"

"When they intend to knock them down," he said, his tone somewhere between humor and truth. The corner of his mouth lifted, amused, as if he were already imagining the crash.

Ciel’s voice cut through the hum. "Do not wander."

"I would not dream of it," I replied lightly.

His answer came sharper than expected. "You have dreamed worse."

The sound of the harbor seemed to fall away. He had not raised his voice, but the words carried the precision of a blade. I saw what lingered behind them, his memory of me lying still at the base of the willow, the light, the fall, the choice I should not have survived. For a moment, all I could feel was the hollow of that impact, the way the world had gone thin and sharp around the edges.

He was still angry that I had even been on the brink of death. Perhaps not because of what I had done, but because it reminded him how fragile defiance can be, even when one wraps it carefully in duty.

"I try to keep better company now," I said quietly.

He said nothing. His gloved hand tightened once around his cane before he moved on, the conversation closing like a door no one intended to reopen.

Sebastian’s gaze flicked briefly toward us, the faintest curve of his mouth hinting that he had heard enough to understand, and more than enough to stay silent. His eyes lingered on Ciel for a heartbeat, then on me, weighing the distance between us with the same clinical care he gave to place settings and knives.

Dorian shifted slightly behind me. The stillness in him sharpened, reminding me that patience was never his strongest virtue. When the world grew too loud, he often went quiet, the kind of quiet that made the air itself seem thinner. I could feel him listening, not to the harbor, but to the breath I had not yet let go.

At the next berth, a small brass band tried to seize the morning with a waltz, the melody drifting across the water in clipped pieces. Children pressed their faces to the railings, leaving foggy marks on the cold metal. Porters chalked numbers onto trunks and slapped tags on handles, their gestures quick and practiced. A woman in a fur collar argued with a clerk about precedence. Another traveler slipped a coin to the stevedore who promised her boxes would be placed within reach of a maid by supper.

Someone near the gangway laughed too loudly, the sound high and brittle. Someone else coughed into a handkerchief and glanced toward the ship with the kind of rigid determination reserved for people who have already decided that this journey will save them.

The gangway crew was already shouting for boarding when the rest of the household reached us.

Finnian came first, hauling a tower of trunks that looked ready to topple. His grin stretched wide despite the effort. "This is the Campania? It is huge."

"Mind your feet, Finny," Ciel said, shifting aside as one of the trunks listed dangerously.

Mey-Rin rushed to help, nearly dropping her own luggage. "Careful, Finny. Her ladyship’s gowns are not meant for squashing."

Bard followed, a cigarette clinging to his lower lip, a crate stamped Fragile balanced on one shoulder. "You would think we were shipping half the manor," he muttered. "Hope the sea has room for your silverware, Sebastian."

Sebastian did not bother to answer, but the slightest lift of his eyebrows said enough.

Tanaka approached last, calm as ever, hands folded neatly behind his back. Snake walked beside him, his pale serpent slipping up one sleeve and down the other like a ribbon come to life. The creature’s head appeared and vanished with the rhythm of Snake’s steps, tasting the air as if unimpressed with the city’s attempts at grandeur.

It was still strange seeing Snake among us, another remnant of the Circus now dressed in Phantomhive black. The livery fit him, but only in the way a borrowed name fits the first time it is spoken. Ciel had insisted he stay, though never explained why. Perhaps mercy had been the rarest part of his revenge. Or perhaps Ciel liked to keep reminders of what he had survived where he could see them.

"Emily says the sea smells like secrets," Snake murmured.

"Then we had best hope it keeps them," I replied.

His eyes flicked to me, uncertain for a heartbeat, then softened as if my answer had satisfied more than one voice.

Sebastian’s smile curved faintly. "An astute observation, my lady."

Dorian’s eyes followed the group with quiet amusement. "He keeps his trophies close," he said. "The boy understands the power of what he has conquered."

I glanced at him. "And what does that say about me?"

His smile sharpened. "That you are the prize no one expected to win."

I felt his words settle over my shoulders with the weight of something both flattering and cruel. A prize is still an object, even if it walks and speaks and makes its own bargains. For a moment, I wondered which of us he thought had done the winning.

Before I could respond, Ciel’s voice cut through the air. "That is enough." He turned slightly toward Sebastian. "Ensure they return to the carriage when they are finished."

Sebastian bowed. "Of course, my lord." He addressed the servants. "You all know your duties at the manor while we are away?"

"Yes, sir," Finny shouted, nearly dropping the trunk again.

Mey-Rin nodded quickly. "Everything will be spotless when you return."

Bard exhaled smoke. "If it burns down, it will not be my fault this time."

"Ho ho ho," Tanaka chuckled softly, the sound swallowed by mist.

Sebastian’s smile stayed polite but cold. "Let us hope not." He gestured to Snake. "You will accompany us, Mr. Snake."

Snake inclined his head. "Emily says she prefers the sea to silence."

Sebastian nodded once. "Then it is settled."

The crew began to load the final trunks. The sound of shifting rope and metal blended with the hiss of steam. Oil clung to the air, thick and metallic. A gull drifted low and shouted at the water, offended by a wake that had not yet formed.

For a heartbeat, there was nothing to do but stand there and feel the day tilt forward. I watched the crew move with the smooth confidence of people who had done this countless times and imagined, not for the first time, what it must be like to trust habit more than fate.

That was when a familiar voice cut through the noise.

"Ciel!"

Elizabeth’s tone was bright, too bright, the kind of cheer that hides exhaustion beneath polish. She moved through the crowd, ribbons fluttering in the wind, sunlight catching in her hair. Her family followed close behind, Lady Francis composed and unreadable, Edward a step behind her, posture taut, and Lord Midford steady at their side, expression carved somewhere between formality and fatigue. Their presence made a small space in the crowd, a careful ripple of deference and curiosity.

"Lady Elizabeth," Ciel greeted evenly.

She smiled, small and hopeful. "When we invited you to join us, you said you would be too busy."

"I decided everyone could use a break," he replied. "London has been demanding."

Francis’s gaze flicked toward me, assessing, then back to Ciel. "So you brought company," she said lightly. "How generous of you to share your respite."

The politeness barely masked the edge beneath it. I could feel the eyes around us. The nobles waiting to board had stilled, their curiosity hanging in the fog like perfume. Somewhere to our left, someone whispered my title, and someone else followed it with a scandal they only half remembered. Scandal is a kind of currency. I had learned how to live with it, even when it was spent in my name without my consent.

Ciel inclined his head. "Her Grace’s assistance has proved valuable to the Crown. I see no reason she should not benefit from a change of scenery as well."

Edward’s mouth twitched, not quite a smile. "How fortunate that duty and leisure align so neatly for you, my lord."

Lord Midford’s voice was steady but dry. "Let us hope this voyage brings calm, not further excitement."

"I am certain it will," Ciel said.

Elizabeth’s eyes darted between them. "It is good that you are both here. I feel safer with you close."

Her words trembled. Francis said nothing, but the silence between them spoke more clearly than any reply. Edward’s hands tightened behind his back. Forgiveness, if it existed, had not yet reached their hearts. They had given their consent for Ciel to continue standing beside Elizabeth. They had not forgotten what it had cost her to do so.

Sebastian bowed slightly. "If it eases your mind, my lady, the Earl will see that this voyage remains entirely uneventful."

Francis’s reply was too soft for kindness. "Let us hope he is more successful this time." She turned before Ciel could answer, as if the conversation had already given him more than he deserved.

Dorian’s voice brushed the air beside me, low and smooth. "Sharp tongues for polished manners."

"You sound impressed," I murmured.

He smiled faintly. "I am. It takes practice to wound without raising one’s voice."

Elizabeth turned to me, her expression gentler, as if she had deliberately shifted to a safer subject. "It has been a while since I last saw you, Duchess. How have you been?"

"Well enough," I said. "The months since London have been clarifying."

Memories flickered at the edge of that word. Blood pooling. Light that hurt to look at. Choices that could not be taken back. Clarifying was the polite word for it, the way one might describe a storm that had torn off the roof but left the foundations intact.

Dorian added, his tone smooth as silk, "A fair way of saying she has grown quite good at surviving the improbable."

Elizabeth hesitated. "That sounds rather dramatic."

He inclined his head. "She is rather dramatic company."

Ciel’s fingers tightened on the head of his cane, the only sign of what he thought of Dorian’s remark. The crowd noise rose again, a ripple of footsteps and voices filling the pause before Elizabeth’s soft, uncertain laugh.

She nodded politely, though she seemed unsure what to make of him. I gave Dorian a sidelong glance. "You make me sound exhausting."

"On the contrary," he said quietly, eyes glinting. "You make everyone else sound untested."

There was a twist of fondness in his voice that most people would have missed. Sebastian did not miss it. Neither did Ciel. I felt their attention without seeing it, two different kinds of scrutiny resting at the edge of my awareness.

Ciel exhaled once, almost a sigh, not quite approval but enough to ease the tension. Elizabeth seemed grateful for the shift.

"Then I am glad you are both well," she said gently.

Ciel inclined his head, and the conversation dissolved into the hum of the docks. The spell of that small, fragile politeness broke, and the harbor rushed back in.

Francis straightened. "We should board, Elizabeth."

Lord Midford offered his arm. Edward followed behind them. Francis paused long enough to meet Ciel’s eyes, cool and deliberate, then turned away.

When they were gone, the sounds of the harbor crept back in. Steam hissed from the pipes. Gulls cried overhead. Somewhere a bell tolled, counting down a morning that could no longer be taken back.

Dorian watched the retreating figures. "The living do carry their ghosts poorly."

"They are not ghosts," I said. "Not yet."

"Give them time," he replied. "Grief fades faster than it pretends to."

For a moment, none of us spoke. A gust from the harbor swept through the fog, carrying the metallic scent of salt and coal. It felt like the world was holding its breath, as if the ship itself could sense it was about to swallow something whole.

Ciel adjusted his gloves. "We board," he said at last.

Sebastian inclined his head. "After you, my lord."

The fog deepened as we approached the gangway. The sound of the crowd thinned to a low hum. The Campania loomed above, polished brass and white steel set against a gray sky, the sort of beauty meant to convince its passengers that comfort is the same as safety. The gangway creaked slightly underfoot, its ropes drawn tight as if reluctant to give us away.

As we climbed, Ciel spoke again, quieter now. "We need to determine why Her Majesty wants us here. She has never cared much for pleasure voyages."

Sebastian’s mouth curved faintly. "Indeed, my lord. Though I find Her Majesty’s timing impeccable."

Ciel gave him a flat look. "How so?"

Sebastian’s eyes drifted over the passengers below. "A fine collection of souls, each convinced this journey will change their lives. It usually does."

Ciel said nothing, his expression unreadable. His shoulders, however, held that particular stiffness that meant he had already begun turning the problem over in his mind, looking for teeth beneath the gold leaf.

I caught the faintest glance from Sebastian as we stepped onto the deck, too brief to be accidental. There was amusement there, and something else I could not yet name, as though he were curious which of us the sea would try to bargain with first.

Inside, the air changed. The scent of oil and salt gave way to perfume and varnish. Passengers in crisp uniforms and satin gowns filled the corridors, their laughter bright and practiced, their smiles already calculating who mattered. A stewardess with a polished badge glided past carrying a stack of folded deck rugs. She smiled with her mouth rather than her eyes.

Ciel’s cane tapped lightly against the marble floor. Heads turned as we passed.

"The Phantomhive boy," someone whispered, as if saying it softly could make it safer.

Another voice followed, hushed but eager. "And the Duchess with him. Imagine the scandal if they were not on royal business."

I kept my gaze forward, letting their words slide past like water against glass. Let them imagine. Let them build whatever stories they needed in order to feel that they understood us. The truth of it was stranger than anything they could afford to believe.

Sebastian managed the formalities with practiced precision, presenting our tickets before the steward could finish his greeting. "The Earl Phantomhive, the Duchess [y/l/n], and their attendants," he announced smoothly.

The steward bowed low. "Of course, sir. Your cabins are ready. If you will follow me."

We moved through a corridor lined with mirrors and brass trim. Our reflections appeared, broke apart, and reassembled with every step. For a moment I saw myself beside Ciel, then beside Sebastian, then beside Dorian, the images overlapping like a deck of cards being shuffled by an unseen hand.

Servants passed with silver trays, their polished shoes whispering against the floor. The faint vibration of the engines stirred below, like a heartbeat beginning to wake. A sign near the staircase instructed passengers to keep corridors clear for the comfort of others. The letters gilded the warning into courtesy.

A boy in a page’s uniform hurried past, arms full of folded napkins, muttering the order of table numbers under his breath. A woman in pearls adjusted her hat in the mirror and glanced at me with quick curiosity before dropping her gaze, measuring in an instant that I outranked her and that her interest would go unanswered.

Our assigned quarters were on the upper deck. When the steward opened the door, I paused at the threshold. The cabin gleamed with polished wood and brass fixtures. The bed was dressed in crisp linen trimmed in gold thread. A vase of lilies sat by the window, scenting the air with something sweet and faintly funereal. A small wardrobe held an extra blanket, two life belts, and a printed card that explained how one might fasten the straps in the unlikely event of misfortune. The ink on the card was still sharp. No hands had yet creased its edges.

Sebastian inspected the arrangement with his usual precision. He checked corners, hinges, the placement of the bell pull. "Adequate," he murmured.

Dorian glanced at him with a half smile. "You call a chandelier adequate. The world has spoiled you."

Ciel ignored them both and crossed to the porthole. His reflection in the glass looked ghost pale in the light, the line of his shoulders drawn tight. "We will reconvene at dinner. Until then, keep alert."

He left without waiting for acknowledgement. The door closed with a soft, assured click.

When the sound faded, the silence felt heavy enough to touch. The rhythm of the engines pulsed faintly through the floor, steady and distant, like a heartbeat that was not my own.

I unbuttoned my gloves and let them rest on the table. The wallpaper shimmered in the light that filtered through the porthole, gilded by the motion of the sea. The ship smelled faintly of beeswax and lilies, but underneath it all lived the colder scent of salt. It threaded through the air no matter how hard attendants tried to drown it in civility.

In the mirror above the desk, my reflection wavered. The light made my skin look paler than usual. The ribbon at my throat sat perfectly aligned, the fabric smooth and respectful. I lifted my hair away from my neck for a moment and felt the familiar thrum beneath the collar, a private pulse that did not belong to the ship. The mark there answered to a different rhythm entirely, one that had nothing to do with engines or tides.

I let my hair fall back into place and smoothed the surface until I looked like myself again, the acceptable version of myself that could stand at a railing and be whispered about from a safe distance. The other version, the one that remembered what it felt like to fall, stayed where it always did, just beneath the skin.

I moved to the porthole and rested my fingertips against the glass. The harbor outside was blurred and small, framed in a perfect circle. Men moved like pieces on a board that someone else had already set in motion. A gull wheeled close, its reflection flashing across the glass before it vanished from sight. For a moment, the round window felt less like a view and more like an eye.

A soft knock at the door. Then Dorian’s voice. "My lady."

"Come in," I said, turning from the mirror and the window both.

He stepped inside, the gold of the chandelier catching faintly in his hair. "We are about to leave the docks. The passengers are gathering on the promenade."

"You came to fetch me?" I asked, adjusting a stray curl back into its pin.

"Sebastian suggested it," he replied lightly. "I prefer to think I beat him to it."

"I suspect you both enjoy pretending you are ahead."

"Only when it is true," he said, smiling.

He offered his arm. I took it. The fabric beneath my fingers was warm from his skin, as if the ship’s vibration had already settled into him and he had decided to claim it as his own. There was comfort in the solidity of him, even when he was the most dangerous thing in the room.

On the way back through the corridor, a stewardess paused to open a door for an elderly couple and said something soothing about the weather clearing by afternoon. A boy in a sailor suit ran past with a paper boat in his hand. His nurse caught him by the sleeve and hushed him with a look. Somewhere above us a violin found the tail of the earlier waltz and tried to coax it back to life. The notes trembled in the air like something uncertain whether it wanted to be joyful.

A pair of gentlemen standing near the stair paused their conversation as we passed. One of them watched Ciel, the other watched me. Neither of them watched the boy who had nearly collided with their boots. That, I thought, was the way of people who believed the world had been built correctly the first time.

When we emerged onto the deck, the sound had changed. The engines had deepened to a low, resonant hum, and a cheer rose from the docks below. Hundreds of faces stared upward, waving handkerchiefs and hats. The fog was lifting, silvered now by sunlight that made the water look almost kind.

On the far side of the harbor, a small champagne launch glided past, its passengers raising glasses as it trailed the ship’s starboard side. Bottles burst open, corks arcing through the air before splashing into the sea. Someone laughed, and the sound carried, bright and careless. For a moment, it almost felt like celebration, as if this were nothing more than a festive separation, a party that happened to take place on water.

"Humans," Dorian said quietly, watching them. "They toast to every departure as though nothing ever sinks."

"Would you prefer they mourn before they set sail?"

He smiled faintly. "No. But I do enjoy the irony."

Snake had found a place near the rail. His sleeve shifted, a pale scale catching the light. "Emily says the salt tastes like old scales," he whispered.

"It is an old sea," I said. "It remembers more than it tells."

He nodded as if the sea had answered him directly, eyes distant in that way he had when listening to voices only he could hear clearly.

I looked back toward the shore. The crowd had begun to blur, faces dissolving into color and movement. Confetti drifted through the air like misplaced snow. The city itself seemed to lean away from us, its skyline shrinking against the horizon. Smoke curled from chimneys, reaching for us as if reluctant to let us go.

A church bell struck the hour. The sound reached us late, as if it had to cross water to find the right name. The delay made it uncanny, a reminder that time moved differently out here, even when the ship’s clocks remained obedient.

The Campania moved forward, slow and sure. The air tasted of salt and metal. Waves struck the hull in rhythmic applause. The deck shivered beneath my feet in a way that was almost like breathing. Someone behind us was crying quietly. Another was praying. Dorian stood still beside me, unreadable, his attention stretched between the scene on the dock and something much farther out.

As the docks fell away, I thought of what Sebastian had said, of the fine selection of passengers and how convinced they were that this journey would change their lives. Perhaps that was what this ship carried most of all. Hope disguised as purpose, gilded and weighty. The kind that always costs more than it promises.

The champagne boat veered back toward shore, its wake cutting a path of white across the gray water. I watched until it disappeared into fog. The wind shifted and carried the faintest trace of coal smoke and perfume. The city’s taste thinned on the air, replaced by something emptier and wider.

Then I saw it.

A figure moving against the tide of the crowd. Swift. Deliberate. At first I thought it was a passenger who had missed their chance. As it neared the edge of the pier, the stride changed. Measured. Precise.

The coat flared in the wind, black against the pale light. Metal caught the sun, a flash of silver, the faint curve of a blade no mortal craftsman would forge. For an instant, green eyes gleamed beneath the brim of a hat.

Then the figure leapt.

"Did you see that?" I asked, my voice low.

Dorian’s gaze followed the spot where the figure had vanished. "See what?" he murmured, though the faint curve of his mouth betrayed him.

The Campania cut forward through the fog. The city slipped away behind us. Whatever had joined us had no intention of leaving.

Far below, the water closed over itself with the neatness of a stitched seam. The ship’s pulse steadied, certain of its course. Ahead, the horizon waited. Behind us, the morning folded itself into memory, and the sea kept its counsel.

Notes:

A/N

Welcome aboard.

Between Tides: Campania Arc is a short interlude series set after the events of Our Little Game Book One and before the next main installment. We are picking up right where the initial work left off and following the Duchess, Ciel, Sebastian, and Dorian onto the Campania to explore the canon cruise arc through the lens of this story.

You don’t need to have every detail memorized, but this mini-series does assume you’ve read Our Little Game first, since it builds directly on the choices, relationships, and consequences established there. And if you would like to drop in and have a refresh, please feel free to look in the series page.

Expect: slow dread, ocean imagery, shipboard politics, and more of the quiet tension between contracts, loyalty, and whatever passes for a heart in this world.

Thank you for stepping from the manor onto the deck with me. Let’s see what waits between tides.
