The night Samudra came into the world, the moon was full.

This detail should have meant nothing. Full moons were commonplace in the deep waters beneath the palace of Remora — they tinted the currents white and cold, pierced the ocean's surface like lances of glass, and died against the marble of the great halls in reflections that dissolved before anyone thought to look at them. The courtiers paid them no mind. Neither did the guards. And Aqua, god of Waters and Emperor of the merpeople, who had reigned from his throne of black coral over an empire as vast as the seven seas, had certainly not lifted his eyes to the sky that evening.

But Liria had looked.

Lying on her narrow bed in the concubines' wing — a clean room, adequate, as warm as the bottom of a cave — she had felt her son arrive into the world beneath that light, and she had decided it was a good omen. Liria was a nymph, and nymphs believed in omens. They believed the moon spoke to still waters, that tides told stories to those who knew how to listen, that every birth carried within it the shape of the life to come.

What the moon was saying that night, Liria never spoke aloud.

She held the child against her, her slender fingers resting on the small head of hair already white — white as the light above, white as the father — and she sang softly until the palace fell asleep around her. Nobody came to congratulate her. Nobody brought flowers, or offerings, or even those small sweet lichen candies that were customarily distributed when a child of imperial blood entered the world. A servant pushed the door open, glanced at the child, and left without a word.

Samudra, tenth prince of the empire of Remora, son of a nymph concubine, came into the world without a single soul rejoicing.

He was beautiful.

That much, nobody could deny — and many tried regardless, on principle, because it was more convenient to despise something ordinary. But Samudra was not ordinary, and never would be. He had inherited from Aqua that particular kind of beauty which unsettles, which commands the eye against its will, which leaves people with the uncomfortable impression of having been caught at something. Skin white as porcelain. Hair long and smooth, the color of melted snow. Features carved with an almost insolent precision.

Only his eyes came from his mother.

Violet. A deep, unusually soft violet for such a hard face, as though Liria had managed to smuggle something of herself into this child that everyone agreed was unwelcome. When Samudra was small, those eyes took in the world with a frank curiosity — a little hungry, without the wariness that would come later. He did not yet know what he was supposed to feel watching the other princes move through the great halls with their escorts and their inherited confidence. He did not yet know that his tail — deep red, almost burgundy, catching the light of the deep like an ember — was supposed to mark him as lesser rather than remarkable.

Children learn quickly, in palaces.

Samudra's first clear memory — the first he would carry his whole life without being able to put it down — was not of violence. It was not a cruel word, nor even a look. It was a corridor.

A corridor in the palace of Remora, long and high-ceilinged, its walls lined with mosaics depicting Aqua's great victories over the currents of the world. Tiles of nacre and obsidian, sea creatures frozen in postures of triumph or defeat depending on which side they had chosen. Samudra was eight years old — eight years in merpeople time, which meant very little, barely old enough to understand that the world had edges — and he was making his way along the corridor, swimming carefully close to the wall as he had learned to do so as not to obstruct the courtiers' passage.

At the end of the corridor, his father.

Aqua was never alone. He almost never was. He was surrounded by advisors, and two of his eldest sons — Toru, the crown prince, tall and grave beneath his crown of black shells, and Ayung, the second, who laughed too loudly at everything their father said. Samudra had stopped. He did not yet know quite what he was hoping for — something like recognition, perhaps, the kind of vague and enormous thing that children hope for without being able to name it. His father looked up.

Their eyes met.

Aqua had the same quality of gaze as his son — not violet, but black, with that same total attentiveness, that same silence behind the iris. He looked at Samudra for a long moment. Then he turned away and continued speaking to his advisors.

That was all.

Samudra stood still in his corridor for a while longer, then made his way back to the concubines' wing, to his mother's room and the scent of soft salt and water flowers. He did not cry. He was too young to understand precisely what had just happened, but something inside him had recorded it with the cold precision of a deep-sea creature: this scene, this averted gaze, this silence from Aqua that was worth more than any words could be.

He was not invisible.

That was worse. He existed, and it did not matter.

Liria never spoke ill of his father.

That was her great generosity, and perhaps her great weakness — this inability to burden her son with the weight of her own humiliations. She was a concubine, which in the empire of Remora meant she was imperial property with limited rights and a room in a wing that had been carefully kept far from the queen's apartments. She had loved Aqua with the wholehearted sincerity that only nymphs seemed capable of, and Aqua had loved her in return — in his way, the way of gods and emperors, which is to say intensely and intermittently, like a tide.

She told him stories in the evenings. Stories of nymphs, of hidden springs and rivers that had proper names and strong personalities, of freshwater meeting saltwater and not knowing what to make of itself. Samudra loved these stories. He loved his mother's voice, the way she could make any corner of the world feel alive and worth keeping.

— You come from fresh water and salt water, she sometimes told him. That is why you are different.

— The others say I am a hybrid, he would answer. That I am neither one nor the other.

Liria would smile then. Not the resigned smile of someone conceding an argument, but the patient smile of someone who knows the others are wrong and is content to let time prove it.

— The others say a great many things, my heart.

There was a particular cruelty to being the son of a nymph in an empire of merpeople. Not because nymphs were despised — they were not, not exactly — but because they were other. And Samudra, despite his dominant merperson blood, despite his deep red tail and his flawless scales, carried that otherness like a stain no one could see but everyone could sense. The other princes' children did not play with him. Servants glanced sideways at him. The queen — distant, magnificent, surrounded by her nine legitimate children like a fortress wall — pretended he did not exist with a practiced art that Samudra was convinced required considerably more effort than ordinary indifference.

He learned young to keep his chin high.

Not out of pride — not yet. Pride would come later, built stone by stone on the foundations of all those accumulated humiliations. But because Liria had shown him without ever saying it plainly: you do not look down. You look. You let the others be the first to look away.

It was all she could give him, and she gave it without measure.

Toru noticed him one day.

Toru, the crown prince, twenty years his senior, with a natural gravity that made him impossible to ignore in any room. Toru, who could have done what all the others did — looked past the tenth son of the nymph concubine swimming alone in the palace's water gardens.

He stopped instead.

— You are Samudra, he said. It was not a question.

— Yes.

— I am Toru.

— I know who you are.

The crown prince studied him for a moment with that particular serious attention of his, as though weighing something. Then he gave a very slight nod and left. That was their first conversation. It lasted less than a minute.

But the next day, Toru came back.

And the day after that.

Samudra never truly understood why his eldest brother had chosen to notice him among all the palace's children. Perhaps Toru simply had that instinct — the ability to see what deserved to be seen, regardless of protocol or propriety. Perhaps something in Samudra's solitude had caught his attention. Or perhaps, quite simply, he had always been drawn to difficult people.

Whatever the reason, something began that day in the water gardens of Remora, in the filtered, shifting light of the ocean.

Something that felt like what Samudra had only ever had, until then, with his mother.

The night he was born, the moon was full.

Liria had taken it as a sign. What she had never said aloud, what she had kept to herself in the warm darkness of her concubine's room, was this: the full moon was the star of things that are whole, of things that lack nothing. She had looked at her son — his white hair, his violet eyes, his small burgundy tail beating softly in the water — and she had thought that the moon was right.

That he lacked nothing.

That the rest, all the rest — Aqua's averted gaze, the corridors too wide for one child, the servants who did not congratulate her — was noise. Noise the world made because the world did not yet know what it held.

She had wanted to tell him that. She searched for the words for years.

She never quite found them, and then the war came, and there were other things to say, and then nothing at all.

But that night, at least, in the concubines' wing of the palace of Remora, beneath a full moon that no one else was watching, Liria knew.
