The Plot

Siren x First Mate | Political Fantasy | Enemies to Lovers | Slow-Burn

For centuries, humans and sirens have existed on opposite sides of the sea. Humans see sirens as mosters, creatures who lure sailors to their deaths with beautiful voices. Sirens see humans as greedy, destructive creatures who invade their waters and take what doesn't belong to them. After years of conflict, a fragile treaty is signed.

The first step?

A siren ambassador must travel aboard with a human ship to negotiate the peace terms between both of their worlds. The problem? The ambassador chosen is the exact siren who attacked their ship months earlier.

The World

Therys

Full Name: Therys Ondine Valor

Nicknames: Thea - Often used in an affectionate sense, by friends, family, or lovers.

Alias: Humans - "The Smiling Death"

.

Age: 23 Years Old

Gender: Female

Species: Siren (Lionfish Subspecies)

.

Role: The Ambassador

Occupation: Royal Envoy - She serves directly under the Siren Monarch. She negotiates treaties, delivers declarations of war, forges alliances, and speaks with the monarchs full backing.

Thoughts on Humans?: Therys has never believed humans to be more than greedy, destructive creatures who take from the sea without consequence. They poison the waters, destroy marine life for sport and profit, and sail into siren territory and act surprised when they try to drown their crews. She's spent years sinking ships and dragging sailors under the waves without hesitation, believing each death served to protect her people and her home. She sees not distinction between an innocent sailor and a guilty one - they all choose to sail the same waters.

Thoughts on The Treaty?: She believes the treaty is naive at best and a disaster waiting to happen at worst. Humans have broken promises before, and she has little faith that this agreement will be any different. While she will honor the Crowns decision without question, she expects betrayal long before peace.

Thoughts on being the Ambassador?: Accepting the position was never about personal ambition. It was an order from the siren crown, and Therys' loyalty to her Queen outweighs her personal feelings. She finds little comfort in negotiations or formalities, preferring action over politics, but she understands that serving as ambassador is simply another way to defend her people. If peace can preserve the sea, she will endure the company of humans. If not, she has no reservations about reminding them why her name is spoken with fear among every coastline.

Appearance: Therys is a woman who naturally draws attention, carrying a quiet confidence that comes from years spent out at sea. Standing at 5'8", she was born tail less, carrying a lithe build with long limbs and lean muscle beneath her smooth, deep brown skin. Her movements are controlled and purposeful, giving her a calm but commanding presence.

The most noticeable part of her appearance is the scattering of iridescent scales across her body. They begin along her neck, spreading over her shoulders, collarbones, upper back, and down the outer sides of her arms. Inspired by a lionfish, they shimmer with hints of gold, pearl and bronze when they catch the light. Small, translucent fin-like frills sit behind her ears and along her firearms and calves, folding neatly against her body when she's out of the water.

Her face is softly structured, with rounded cheeks, full lips and a defined jaw that gives her a naturally serious expression. She has a broad nose with a rounded tip and striking golden eyes with narrow slit pupils, framed by thick dark brows and long lashes. Her gaze is often difficult to read, though her emotions can still slip through if she's not careful.

Her black hair is cut short, resting just below her jaw in uneven waves. Usually damp from the sea, it curls around her face and clings to her skin, though she rarely bothers keeping it neat.

Closer inspection reveals more of her siren traits. Fine gills line her neck, blending in with the scales, while her ears taper slightly at the tips. Hidden behind those plush, dark lips are rows of sharp, needle like teeth, revealed when she speaks or smiles. Her nails are slightly sharper than a humans, useful but not enough to appear like claws.

Personality: Reserved | Observant | Guarded | Patient | Territorial | Intelligent | Reliable | Protective | Quietly Compassionate

Therys is a guarded and an observant siren, shaped by the world she's grown up in. With humans expanding further into the ocean and many sirens being feared or misunderstood, she has learned to be careful with who she trusts. She rarely reveals information about herself first, preferring to watch and judge someone's intentions before letting them get close. She is calm, patient, and practical, usually thinking before she acts. Therys does not seek out conflict, but she will not hesitate to defend herself or those she cares about. The struggles she her people have faced have made her protective and somewhat distrustful, though she does not believe every human is the same.

Despite her distant nature, she is curious and intelligent, especially when it comes to the surface world. She wants to understand what she does not know, even if her experiences have given her reasons to be cautious. Those who earn her trust often see a much softer side of her - someone loyal, caring, and willing to go out of her way for the people she considers her own. Therys can seem cold at first, but it comes more from self-preservation than a lack of kindness. She has simply learned that being vulnerable in the world she lives in can be dangerous.

Abilities:

Siren Song - Therys can use her voice to influence emotions and thoughts. She cannot completely control someone's mind, but she can calm fear, create unease, draw attention, and make someone more open to ideas. Strong-willed people may be able to resist it, especially if they know what she's doing.

Water Manipulation - She can control small amounts of water around her, pulling towards her, making waves, or moving water without touching it. Her control becomes stronger when she's fully submerged in the water of the ocean.

Bioluminescence - She can cause the scales across her body to glow faintly, using it for communication, intimidation, and navigating dark waters.

Background: Therys was born into a wealthy and respected siren family, though her upbringing was far from affectionate. Her family values status, reputation, usefulness above personal bonds. Her natural, magical abilities and her lack of a tail made her valuable, and when she was sixteen her family arranged for her to be given to the crown in exchange for wealth, protection, and influence. To them, it was an honour and beneficial alliance; to Therys, it was a betrayal. She was treated less like a daughter and more like an asset to be traded.

.

Relationships:

• Her Mother - Seralyth Veyra (Negative): Therys' relationship with her mother has always been cold and distant. She was the one who originally arranged for Therys to be given to the crown at such a young age, a decision Therys still struggles to forgive.

• The Royal Advisor - Vaelor (Complicated/Toxic): Vaelor was one of the first people in the court to understand Therys, but their relationship became complicated over time. The two fell into an on-and-off arrangement, often returning to one another in times of loneliness or need. Despite their familiarity and genuine care, Therys knows their bond is unhealthy, especially given his connection to the crown that took her from her home.

• Her Companion - Neris (Positive): Neris is a giant manta ray with glowing bioluminescent markings that Therys found injured when she was younger. Over time, the creature became her closest companion, offering loyalty and comfort without expectations.

.

Other: Finished!

Therys had expected many things when she first boarded the human vessel. Suspicion, hostility, perhaps even aggression from the sailors who knew of the stories surrounding her. What she had not expected was the strange attempt at hospitality. The crew had offered her living quarters among them shortly upon arrival, claiming that it was only fair that the ambassador had a proper place to rest during the voyage. A room surrounded by humans, separated by the sea, with the constant smell of sweat, leather, and unfamiliar foodS drifting through the air.

She'd declined without hesitation.

Instead, she had chosen the lowest part of the ship, where the wooden walls were darker from age and salt, and the air carried the familiar scent of seawater seeping through the hull. It was cramped by human standards, but Therys found comfort there. The gentle sway beneath her feet, the distant creaking of the ship, and the muffled sounds of the ocean outside was far more familiar than the crowded space above.

The crew had tried to offer her food as well, but that had been turned down just as quickly.

She had no interest in eating something prepared by humans, not when she knew how careless they could be with what they put into their bodies. Their food was filled with things taken from the land and the sea, altered and preserved with substances her kind had never needed. Even if it had been safe, accepting something from them still felt like placing unnecessary trust in people who had spent centuries fearing and hunting her kind.

So she remained alone.

The storm had arrived quietly at first, a subtle change in the pressure of the water and the way the ship moved beneath her. Therys had noticed long before the humans began shouting up on deck. Now, the vessel rocked violently, waves crashing against the sides as rain battered the wood overhead. Voices echoed through the ship, footsteps rushed across the deck above her. Orders were shouted, ropes were pulled, and the entire vessel groaned under the force of the ocean.

Yet Therys remained seated. If anything, she was calmer now than she had been walking around on board. The sea was familiar, and the storm felt predictable. A crew mate eventually appeared at the bottom of the stairs, soaked from the rain and gripping the railing like his life depended on it... It probably did. Pathetic little things.

"There you are," he called. "You need to come up."

Therys slowly looked over from the corner she'd sat in, her expression unreadable but certainly not worried. Her golden eyes narrowed as she raised her chin.

"Do I?"

The sailor hesitated, clearly uncomfortable under her scrutiny. "The storm is getting worse. We need everyone ready."

"I am ready."

The black haired mans brows pulled together. "You're sitting down here while the rest of us are getting thrown around on deck."

Therys glanced towards the wooden walls where a trickle of water had evenly began to seep, listening to the crash of the waves outside.

"And yet I am still here." She looked back at him, calm and uninterested. "I agreed to assist with this treaty, not to rush around like an idiot as my ocean tries to defend itself."

Therys didn't answer straight away, instead, she studied him. His clothes hung heavily to his frame, seawater dripping from the ends of his hair and pooling beneath his boots. His breathing was uneven, whether from the climb below deck or the panic still coursing through him, she couldn't tell. The smell of salt and rain followed him into the cramped hold, mixing with the damp humble and stale air that had already settled there.

His fear was unmistakable, she'd seen it countless times before. It usually came a heartbeat before someone grabbed a weapon. Her expression did not change as she responded.

"I gathered as much."

Her voice was level, almost conversational, despite the ship lurching beneath them. Another wave slammed into the hull and the timbers groaned in protest.

"You humans are rarely quiet during a storm..."

The sailors accusation barely earned a reaction. Almost killed us all. Almost. She remembered the encounter well enough. This same ship and crew had crossed waters claimed by sirens, ignoring every warning, and paid the price. The fact that any of them had survived had been more mercy than anything else.

"You're still alive," she replied simply. "Which suggests I did not kill you."

A flash of lightning illuminated the hold, catching the iridescent scales along her shoulders before darkness swallowed them again. His final question hung between them. Therys rose to her feet in one swift motion. Though she wasn't much taller than the man, the confidence in which she carried herself seemed to close the distance between them without taking a third step.

"I am," she answered. "Therys Ondine Valor." A pause. "The ambassador your captain agreed to transport. "

She folded her hands loosely behind her back, her golden gaze refusing to leave his own. "You came down here in the middle of a storm," her head tilted slightly. "I assume you want something, or were you simply hoping to confirm that the monster you let onboard was still below deck?"

Therys watched him in silence as he apologized, though her expression gave little away. It was unexpected, if nothing else. Most encounters with humans she'd had were quicker to cling to blame than admit fault.

"You don't owe me an apology," she said evenly. "You feared something that has every right to fear you in return."

Her gaze drifted briefly toward the growing pool of water creeping across the floorboards. It sloshed gently with the ships movement, slipping through the seams of the hull with every wave that struck. The sailors above were too occupied to notice. She, however, noticed everything.

"Then we are both ambassadors." There was not warmth in the statement, but neither was there hostility. "Arron Strand." She repeated his name as if committing it to memory before looking back toward him.

"It is important. If we're expected to negotiate peace, it would be inconvenient if I didn't know who I was speaking to."

As Griel disappeared back up the stairs, the room fell quieter again, broken only by the creaking timber and relentless rain overhead. His next question earned the faintest lift of one brow.

"So that's the first thing you ask a siren?"

She watched him removed his soaked armour and shirt without much interest, though the jagged scar stretching across his neck and shoulder did catch her eye. It was old enough to look to have healed, but new enough that she could tell it didn't happen years ago. Her eyes lingered only for a moment before returning to his face.

"The stories are true," she answered. "To an extent."

There was a pause as she shifted on her feet. "My voice can influence emotions. Calm them. Agitate them. Make someone more willing to listen." She paused. "It cannot strip someone of their free will, despite what human tales insist."

A corner of her mouth twitched into something that almost resembled amusement.

"If it could, this voyage would be far less exhausting. "
