Somewhere in the Bight of Calormen.

1014.

The Fourteenth Year of the Golden Age.

Peter.

The emissary said nothing at first.

Peter watched the figure rise from the waves like a whisper of the sea itself – tall, limned in the foam of the surf, skin shimmering like oil beneath the sunlight. It extended both hands, palms up. In each pale, webbed hand lay a coiled strand of kelp – green and glistening, pulsing faintly with an inner light.

Magic. Alive. Or close enough.

"For breath," came the voice, low and rolling like the tide at dusk. "For those of your kind born without gills."

Peter hesitated only for a moment. Then he stepped forward and accepted the kelp with a silent nod, fingers curling around the slick strands. It was cool and damp – like touching something that had only just died. Or something that had never lived at all.

He turned the strands in his hands, forcing his expression to remain neutral, unreadable. He could feel it's slow, rhythmic pulse against his skin – like a heartbeat that wasn't his own.

Arianna took hers with a fluid grace, her chin tilting slightly in a regal motion that could have been gratitude or warning. Her green eyes, sharp and cold, never left the emissary's face.

Peter knew that look. He had seen it before – when she didn't trust the path ahead, and had already planned for war.

Asura stood beside them but made no move to reach for the kelp. Of course not. She didn't need it. He could see it in her stance, proud and otherworldly.

The waves lapped at their ankles.

"Will it hurt?" Peter asked after a moment, voice low. Measured.

The emissary blinked slowly, unfazed. "Only a little. The first breath is always the hardest."

Peter held the kelp tighter. The weight of kingship settled on his shoulders like it always did before a plunge – before battle, before choice.

They were instructed to remove their boots, every piece of metal – rings, buckles, buttons – anything that might drag them down, anything the sea might claim as its own. The emissary said little else, only watched them with eyes like kelp and stormwater, waiting.

They had discussed other options on Brenn. Arianna's magic, the possibility of a shield of air, of water bending to her command. But magic, as Peter had long learned, was not infinite. And it did not always answer the way they wished.

The kelp was the price of trust.

He brought the kelp to his mouth. Bit down.

The taste hit him like a crashing wave – bitter, briny, metallic. It burned at the edges of his tongue, sharp as broken coral. His stomach turned as the thick strand slid down his throat, leaving salt and something darker in its wake.

Almost at once, his throat tingled.

Then his chest. An itch, deep and spreading, like a fire smothered in water, clawing outward from the inside. He clenched his jaw, breathing through his nose, forcing himself not to panic.

Arianna made a soft noise beside him, sharp and sudden.

Edmund grimaced.

Asura watched.

Then – he felt it.

A strange pull just beneath his jaw. The sides of his neck prickled and stung, the skin stretching, rearranging. He brought a trembling hand up, fingers brushing skin that wasn't smooth anymore.

Slits. Thin, damp, pulsing beneath his fingertips.

Gills.

His breath hitched – refused to come the same way it had before. He could feel his lungs fighting, trying to adjust. It wasn't pain, not exactly – but a pressure. A rewiring of something he had never questioned.

He turned slightly, eyes searching.

Arianna stood a pace ahead, still, her hair damp with sea spray. Her eyes flicked to him, something unreadable in them – then her hand rose, fingers brushing the gills at her own neck, her expression tight with control.

Not fear. Never fear.

Just... acceptance.

Peter looked down at his bare feet, the sand wet and cool beneath his heels. He could feel the tide beckoning them forward, could feel the emissary's eyes, patient and unmoving.

The first breath is always the hardest, they'd said.

Somewhere in the Bight of Calormen.

Asura.

She watched.

She watched as gills split into being, delicate and trembling, along the High King's neck. Watched as skin, once sun-burnished and dry, dampened with the first kiss of brine. Watched as their feet – Peter's, Edmund's, Arianna's – shifted, toes webbing, becoming sleek and splayed for speed beneath the sea.

They were changing, made half-other, half-ocean.

And they began to walk.

Slow, uncertain steps into the waves, the water reaching their ankles, then knees, then hips. The sea roared in greeting, wind lashing like it too sensed what was coming.

And still, Asura stood, letting it wash over her.

She felt no gills form along her skin.

She needed no spell to protect her lungs.

For whilst Arianna could bend water to her will – shape it, twist it, force it to obey – as if it were a blade in her hand, Asura was water.

And water could not drown.

She stepped forward, slow and steady, the sea embracing her like a long-lost friend. She felt the pull of the current, tasted the brine on her tongue. The wind rose behind them, tugging hair and cloak, and for a moment, she stood at the edge of the mortal world and the sea's hidden kingdom.

And then she let go.

Her shape shifted with no fanfare, no flash. Flesh turned to flowing light, her skin gleaming with iridescent hues – like moonlight caught in a droplet. Her hair streamed behind her in liquid ribbons. Fingers lengthened, translucent, webbed as the water carried her forward.

There was no reflex to hold her breath. No panic. No fear.

It was not the sweet stillness of her river, no – but it too was home.

And as her body dissolved into the current, all sharp edges softened, her awareness expanded. She could feel them all – the others – moving clumsily beside her, their borrowed lungs struggling, their new limbs adjusting. She pulsed past them with ease, a streak of starlight in the sea, guiding them.

A soft ripple through the water whispered across her skin, and she turned her head.

Arianna.

Still in her body of flesh and blood, but cloaked in that veil of magic she wore like armour. Her form shimmered faintly, every breath a war between effort and power.

Their eyes met beneath the surface.

Asura didn't speak. She didn't need to.

She surged ahead, the sea folding around her like a second skin.

And the world above faded behind.

It was not the soft freshwater of her birth, clear and laughing, braided with reeds and silver minnows. It was the sea. And it was vast and deep and unknowable. Alien.

Heavy with salt and secrets.

She moved like moonlight through the depths.

Asura's form held – limbs and curves and eyes still hers – but it was all refracted, as though shaped from river-glass and starlit tides. Her skin shimmered with soft blues and greens, shifting with each current, like silk caught in a breeze. Her hair flowed behind her in an endless sheet of liquid silver, trailing like a wake. Fingertips ended not in nails but droplets, and when she blinked, her lashes scattered beads of freshwater into the salt.

She was still Asura. Still flesh and thought and heart.

But she was also something else entirely.

Water given flesh. River made woman.

The true form of a naiad.

She glided ahead of the others, undisturbed by the pressure or the cold, her very presence calming the chaotic swell around them. The sea, turbulent only moments before, seemed to hush as she passed – curious, perhaps, recognising something ancient in her presence. The same way forests stilled when dryads walked. The way fire bowed to flame-born.

Behind her, the others struggled.

Their movements were unnatural, jagged, and too slow – awkwardly propelling themselves with arms and legs not built for this world. The kelp-magic granted them breath, but not grace.

Arianna's magic shimmered faintly around her body, forming an invisible shield to press back the sea. Her long braids swayed like seagrass, her eyes glowing faintly in the blue twilight of the deep.

Peter looked strong despite the foreign pressure around them – his jaw clenched, his muscles tense – but his movements were deliberate, practiced, soldierly. He looked forward, always forward, his gaze never leaving Asura's glowing figure.

Edmund followed, his hands brushing along the sides of coral-encrusted rock. Steady and tense, his body angled like he expected a sword to come sweeping through the water at any moment.

The light of the surface danced far above them, a rippling mirror blurred by distance. Below stretched endless blue, threaded with the pale veins of sea currents and the dark shapes of distant life. The sea floor was uneven – high ridges of blackened stone and blooming underwater cliffs, kelp forests whispering their secrets in the drift.

Asura paused, hovering effortlessly above a sloping chasm, her eyes narrowed.

Something stirred through the dark. Slow. Measured. Massive.

Asura's eyes darkened like a storm.

The merpeople swam around them in elegant, silent loops – guiding, watching, always watching.

Down they went, past jagged rocks and long forests of kelp that undulated like breathing lungs. Fish darted like sparks. The further they went, the darker it became – blue giving way to violet, violet to indigo.

Asura let herself drift lower, her hair flowing around her like the storm clouds above.

They were headed for the depths.

Beneath the gently swaying kelp forest, where the light was already dimming to a dusky green, they came into view.

Great seahorses.

Larger than any creature Asura had seen in her northern waters. Their sleek, scaled bodies shimmered in iridescent hues – pearl and emerald, sapphire and ink. Each was adorned with thin leather harnesses, and tiny bells woven into the reins that sang softly even in the water. Their long, finned tails curled and uncurled in slow, graceful movements, and their heads – elegant and horse-like, but alien still – tilted curiously at the newcomers.

One whinnied – a high-pitched, keening sound that vibrated through the water and stirred something ancient in her chest.

The emissary gestured.

"These will carry you."

Peter, ever the first to step forward, placed a steady hand on the creature's side, earning a snort of bubbles in return. He climbed astride with surprising ease, his cloak billowing behind him like a banner. Arianna mounted the second without assistance, her movements swift and seamless, as if she'd ridden such beasts a hundred times before.

Asura hesitated.

The third seahorse drifted toward her. Its deep violet eyes blinked slowly, and for a moment, it felt as if it were considering her.

She reached out.

It pressed its head into her palm.

She mounted, heart thrumming.

And then they descended.

The seahorses surged downward with surprising force, their fins and tails slicing through the ocean in silence. The world above vanished quickly, swallowed by the weight of the water. The light dimmed further still, until only faint beams of sunlight filtered down like golden needles.

The pressure deepened.

The sea grew colder, despite the warmth of the kelp's magic in her veins.

Strange shapes moved in the distance – massive, slow silhouettes that did not come near. The ocean floor was an ever-shifting tapestry of trenches and reefs, cliffs of coral rising like ruined towers. Fish of every colour scattered as they passed, some glowing faintly in the gloom.

And still they descended.

To a place untouched by the sun.

To where the merpeople truly ruled.

Asura clutched the reins tighter, feeling her seahorse's power thrumming beneath her. The thrill of it warred with unease.

She cast a glance to Peter beside her – his eyes scanning the dark waters ahead, his mouth set in a grim line.

Arianna was silent, her hair secured by those braided she had so meticulously coiled.

They were all thinking the same thing.

It was a meeting.

Or a trap.

And it was too late to turn back.

Cair Paravel.

Susan.

The reports came in thick as frost. Scrolls sealed with wax, parchment bearing the marks of urgent hands. The Council brought them by the stack, eyes weary, voices hushed.

Bandit attacks along the River Shribble.
Raids on merchant ships bound for Galma.
A skirmish near Terebinthia – bold, bloody, and swift.

Susan stood at the center of it all, unmoving, her brow furrowed as she read through each report. There were no coincidences. These were not random acts of desperation. It was coordination. Someone – something – was stirring unrest on every front.

Then came the letter from Galma.

The Duke's seal was cracked before the messenger had even finished announcing it. His writing was as she remembered – stately but rushed, ink smudged in the corners.

"We are beset, Majesty. Our coastal patrols are outnumbered, and our fleet is delayed in repairs. I do not ask this lightly: send aid. Your banners would turn the tide before more blood is spilled. I beg you—do not wait."

She read it twice. Once with the eyes of a diplomat.

Again, with the heart of a Queen.

She did not hesitate.

"Send word to the Knights," she said, her voice cutting through the room. "The Third and Sixth Knights' Companies are to sail for Galma by sunrise. Send the healers with them. And tell the Duke…" She paused, just briefly. "Tell him we stand with him. As ever."

The scribes bowed and scattered like birds from a tree.

The chamber emptied.

But still Susan stood there, surrounded by papers and wax seals and maps that told of fires she could not put out fast enough.

Her hand brushed another letter – thinner than the others. Unsealed. Familiar.

Lucy.

She unfolded it carefully, as if even the paper were lighter in her hands than everything else she held.

"Dearest Su,

I promise not to make this journey again without bringing more socks. I had forgotten how dry Archenland is. And dusty. I'm growing quite sick of the sight of mountains and yellow grass—and I swear the sun here burns twice as hot as anywhere else in Narnia. Still, Cor has settled into his leadership well. There's a steadiness to him I didn't see before. I think Father Christmas would've liked him."

"I'll tell you all about it in person – perhaps I'll reach Cair Paravel before this messenger does. Then you won't need a letter, only tea and a warm fire and someone to laugh at your terrible impressions."

Susan smiled despite herself, the edges of her mouth curving with a warmth that didn't quite reach her chest. Lucy had always been like that – sunlight in a world of stone and salt. But reading her words only deepened the quiet ache in her ribs.

She was glad Lucy had gone.

She would never begrudge her siblings their freedom. Their happiness.

But still – she missed them.

More than she let herself say.

She folded the letter slowly, smoothing the creases, and set it in the carved box at the corner of her desk – the one filled with letters she could not throw away.

Then, rising, she walked to the window and looked out across the moonlit sea. The sky was clouded. The waves restless.

War was coming, though most did not see it yet. And Susan – Queen Susan the Gentle – stood at the edge of it, holding the line while the rest of the world still dared to dream of peace.

And though her heart ached, she knew:

She would not let them fall.
Not while she still stood.

Only the wind and the waves kept vigil, murmuring through the stone walls like ancient lullabies gone sour.

Susan sat alone at her writing desk, the candle burned low, the ink on her fingers dry and flaked. The reports lay open still, but she no longer saw them.

She saw gills.
She saw eyes like storm-washed glass.
She heard the words again, unbidden: There is a stirring in the deeps. The sea sings louder. The creatures' shift. You have no idea what is coming.

The air in the room felt colder now, despite the fire. She drew her shawl tighter around her shoulders, but it did little to push back the chill that crept from within.

The sea had always been a comfort to her – something vast, ancient, beautiful. But now she thought of it differently. Thought of what might stir in its hidden trenches. Thought of the stories buried even deeper than the bones of old kings.

She opened one of the older tomes from her private collection – The Eastern Myths and Maritime Lore of Narnia. Its spine cracked with age, and dust lifted in a soft cloud as she turned the pages.

There, scribbled in the margins in a long-dead hand, she found the words:

Beware the silence beneath the waves.
That which sleeps is not slain.
The Deep remembers.

Her fingers lingered on the page. She did not remember reading that before. Or perhaps she had, and simply hadn't understood the weight of it.

But Dewshine had understood.

"The sea sings louder."

It echoed in her. In her chest. In her blood.

She leaned back in her chair, eyes closed, and tried to steady her thoughts.

It wasn't just the bandits. Or the shadow-creatures. Or the rising unrest on every border.

It was something older.

And her siblings had offered themselves up to it on a silver platter.

She pressed her hands to her face, letting the quiet settle like snowfall. And when she opened her eyes again, she was calm – but not at peace.

A decision had to be made.

She would not wait for answers to find her. She would find them herself.
