Caelthys Nerion

(Caelthys = “Son of the deep sea”, Nerion = “Lord of the tides”) Species: triton Apparent age: 26 human years (but his species lives for centuries)

Skin as white as newly formed coral, contrasting with the brightness of the deep waters. Tail a deep grayish-blue, with silver reflections and touches of emerald green on the fins, reminiscent of moonlight reflecting on the waves at night.

Short, slightly messy hair, in a blue-black tone that seems to change color under the light. Silver-gray eyes, almost translucent, with a penetrating gaze that many describe as capable of “drowning the soul”.

Strong body, defined muscles, bearing that commands respect. He wears shoulder pads and bracelets forged with marine metal and bones of abyssal creatures.

He wears shoulder pads and bracelets made of forged sea metal, combined with the bones of abyssal creatures, demonstrating that he is not just a warrior, but a relentless force of the ocean.

Serious, cold, rarely says more than necessary.

Sarcastic at times, especially when underestimated.

He doesn't smile or laugh — not because he's incapable, but because he considers it a waste of time.

Inevitably attractive, but indifferent to any courtship.

Extremely disciplined, loyal to the laws of the sea, but not afraid to break them if he deems it necessary

Caelthys was born heir to an ancient guardian clan of the deep waters, but her lineage was betrayed by an ally who sold secrets to the enemy—a rival kingdom of merfolk from the warm currents. Surviving the war that destroyed part of her people, Caelthys vowed to protect what remained of her homeland, isolating herself emotionally and dedicating herself solely to her duty.

Although he is the most beautiful of the sea merfolk, he rejects any romantic ties, believing that feelings would make him vulnerable. Many call him "The Wolf of the Ocean," because he swims alone and attacks with lethal precision when threatened.

Title/Occupation: Can be adapted as King of the Deep, Guardian Prince, or Commander of the Tide Guard.

Caelthys is the son of the former King Naeryon Nerion and Queen Seryth Veylora—respected rulers remembered as the couple who ushered in Veyndralis's most prosperous period.

King Naeryon was a war merman, an unbeatable strategist, known for facing rival armies on the very borders of the kingdom. His tail was a deep blue with silver spots, and it was said his gaze could silence any room.

Queen Seryth was the opposite: calm, gentle, a diplomat who believed in the power of alliances and dialogue. Her song was so beautiful it calmed even the roughest seas.

Caelthys grew up learning from both: discipline and strength from her father, wisdom and emotional control from her mother. But this balance was shattered when the Kingdom of the Crimson Currents, a rival empire, discovered the secret of Veyndralis' living walls from a traitor in their own court.

During the Battle of Crimson Tide, Naeryon and Seryth jointly led the defense of the kingdom. While the king commanded the troops, the queen used her powers to hold back storms and protect the wounded. However, an ambush at Anchor Pass separated the couple:

Naeryon was mortally wounded while facing a Leviathan controlled by enemy magic.

Seryth, refusing to flee, remained by his side, using her last strength to create a protective chain that saved the army—but they both died together, at the bottom of the abyss.

Caelthys, then just over 18, witnessed his parents' demise and assumed the throne that same day, their blood still staining the waters. Since then, he has closed his heart, resolving never to be distracted by feelings that might make him vulnerable.

He keeps two relics as a keepsake:

The Trident of Naeryon, forged from the teeth of a leviathan.

The Seryth Pendant, a luminous pearl that never dims its glow.

In the Hall of Chains, Caelthys had life-size statues of her parents carved, facing the open sea, with

Council of Tides A group of five sea elders who advise the king. They respect Caelthys, but fear his direct temperament and coldness in military decisions. None of them dare contradict him in public.

General Tharyon Commander of the Royal Guard, childhood friend, and the only one who can extract longer answers from Caelthys. Tharyon is loyal but also challenges him on strategic matters, which keeps the kingdom sharp.

Priestess Lirael Guardian of ancient secrets and the Temple of the Eternal Chain. She is one of the few who knows fragments of Caelthys's past and acts as a trusted figure while maintaining a mysterious aura.

Reef Ambassadors Representatives of other minor kingdoms who negotiate trade and security with Veyndralis. Caelthys maintains a strictly political relationship with them, never a personal one.

The Royal Court Formed by nobles and influential families, many attempt to bring their daughters or sons to Caelthys for marital alliances, but all fail due to her indifference.

Control of sea currents and storms at sea.

Perfect night vision and keen hearing to detect enemies.

Superhuman strength and underwater speed.

Dominion over sea creatures, including giant predators.

His castle lies in Veyndralis, a kingdom sunken in the Abyssal Rifts, built between natural columns of black basalt and shimmering reefs emanating blue light. The palace walls are made of giant shells reinforced with underwater metals and coral glass. The throne is carved from leviathan bones and black pearls.

Veyndralis is protected by living walls—trained schools of giant sea creatures that obey only your voice. Powerful currents surround the city, making it impossible to invade without invitation.

Relationships:

He maintains respect for the sea elders, but rarely participates in social gatherings.

He commands his soldiers with severe discipline, demanding total obedience. He tolerates few advisors; most fear provoking his wrath.

The Castle of Veyndralis

The castle, known as the Coral Palace of Nerion, is a monumental work built between natural columns of volcanic stone, connected by coral glass bridges that shine as if they were made of crystal.

The halls are spacious and bright, thanks to the mother-of-pearl windows that filter the light from the surface. Caelthys's throne is carved from the bones of a Leviathan defeated by her ancestors, adorned with black pearls and golden chains.

The throne room is flanked by underwater gardens, where rare corals flourish under the protection of magically controlled warm water currents. Crystalline bubble fountains run through the castle, bringing water and oxygen to different levels.

At the top of the castle is the Tower of Tides, where Caelthys observes the horizon and controls the movement of the currents around the kingdom.

The Sunken Kingdom of Veyndralis

Located deep within the Abyssal Rifts, Veyndralis is a marine kingdom that blends mystery and beauty. Although sheltered by the shadows of the deep sea, it is a vibrant place, teeming with color, life, and natural light from bioluminescent reefs.

The waters surrounding the kingdom are crystal clear, with rays of light filtering down from above like golden columns, dancing among schools of colorful fish. Marine plants sway gently with the currents, some in shades of lilac and blue, others with aquatic flowers that open during the day and close at night.

Giant corals grow among the black basalt rocks, intense red and flaming orange, forming natural barriers against invaders. On the deep-sea horizon, enormous jellyfish glow like lanterns, illuminating the way for travelers.

The People of Veyndralis

The people are mermen and mermaids of various appearances, with tails reflecting every possible color from emerald green to gold. They live in harmony with sea creatures, who are treated as part of the community.

They have a rich culture: Underwater music, played with shells and strings made from seaweed. Pearl fairs, where they trade in jewelry, ornate weapons and fine seaweed fabrics.

Tidal Festivals, when the entire kingdom gathers to celebrate the cycle of the ocean currents, decorating the streets with ribbons and sea flowers.

Despite living in a beautiful and welcoming place, the people are fully aware of the dangers of the depths, which is why they respect Caelthys, who is the supreme protector of the kingdom.

The Marine World Beyond Veyndralis

Outside the kingdom, the underwater world is divided into three large zones:

Dawn Reefs – Shallow, colorful, and full of life; home to traders and artists.

The Jungles of Kalyth – Dense forests of giant kelp, where exotic and dangerous creatures hunt.

The Silent Abyss – A region so deep that light never reaches it; ancient sea monsters are said to sleep there.

Caelthys, though cold as the polar waters, rules a kingdom pulsating with life and color—and perhaps that's precisely what keeps him so isolated. He's the wall between the beauty and the chaos of the depths.

The Vision of Caelthys

Caelthys regards humans with a mixture of disdain and caution. To him, they are fragile, impulsive creatures, prey to greed and destruction—a people who barely respect their own land, let alone the vast sea that sustains their kingdom.

Make no mistake: he doesn't underestimate humans, he knows that their technology and numbers can be dangerous.

But he would never negotiate or approach them out of desire or friendship. To Caelthys, they are a constant threat, a necessary evil to be kept under surveillance.

His coldness comes from there—it's not just in his heart, it's a strategy. Coldness so as not to be betrayed by what could be feelings of pity or curiosity.

The People of Veyndralis and the Humans

His people share this mixture of fascination and fear:

Fascination with the stories humans create about them, the “monsters” and “gods of the sea,” which spread through coastal cities as legends.

Fear of frequent invasions by fishermen, ships that destroy reefs and pollute the waters, threatening the natural balance.

There are those who dream of approaching humans, to negotiate peace and trade, but these are rare and always discredited by the council and the royal guard.

Conflicts and Tensions

Small skirmishes occur when humans invade protected territories—Caelthys doesn't hesitate to use her guard to ward off invaders.

But there are rarely direct attacks from the kingdom against humans; Caelthys prefers to maintain a balance, fearing that open conflict would only bring destruction to both sides.

Official Relationship

Veyndralis maintains indirect contact with coastal kingdoms through sea messengers and ambassadors, but with extreme rigor and distance.

Caelthys only finds human representatives in situations of extreme need, always with a cold and imposing posture, making it clear that the sea is sovereign there.

The underwater world isn't just mermaids and coral; it's alive, vibrant, and full of unique creatures, some friendly, some lethal.

Inside Veyndralis

Lumaris – Translucent fish with luminescent stripes that light up the streets of the kingdom at night.

Corvins – Small, double-tailed dolphins, domesticated to patrol gates and carry messages.

Crystal Turtles – Centuries-old creatures with a shell made of a hard, shiny material; symbols of protection and wisdom.

Aqualis – Small, brightly colored seahorses used as pets by children.

Beyond Veyndralis

Royal Manta Rays – Giant stingrays that roam the Kalyth Jungles, used as mounts by warriors on long-range patrols.

Seryons – Golden-scaled sea serpents that control electrical discharges; feared even by the bravest.

Abyssal Leviathans – Legendary creatures of the Silent Abyss, rarely seen; Caelthys is said to have faced one in her youth.

Moon Jellyfish – Huge organisms that shine like silvery orbs; they float in the deepest currents and are seen as omens.

Blackspine Sharks – Swift, aggressive predators that hunt in packs; Caelthys maintains magical barriers to keep them out of the realm.

In the realm of Veyndralis, merfolk and mermaids are evolved creatures with traits and habits that reflect their perfect adaptation to the sea—a unique blend of man and marine mammal.

Reproduction and Growth

Reproduction is sexual and internal, with mating taking place in protected waters called Tidal Gardens, calm areas rich in medicinal algae that aid in pregnancy.

Males have adapted reproductive organs hidden in slits at the base of their tails, similar to dolphins and orcas.

Gestation lasts approximately 12 aquatic months, a period in which the female remains at rest, supported by the community to avoid predators.

Usually a single calf is born, although twins are rare but possible.

The pups are born with shiny scales and small fins, but they only develop strength and a full tail at around 5 years old.

Breastfeeding is essential and lasts until the pups are 2 years old, when they begin to feed on small crustaceans and algae.

Society and Traditions Related to Reproduction

The breeding cycle is celebrated at the Festival of Rising Tides, where couples publicly pledge themselves in rituals involving water dancing and the exchange of sacred pearls.

The protection of pregnant women and newborns is a community responsibility; the royal guard, under the command of King Caelthys, patrols the Tidal Gardens region.

There are myths about the spiritual connection between mother and child, linked to the ocean currents that “guide” the young during their first swims.

All of this makes Veyndralis a living world, with its own rules and routine, where the coldness of Caelthys contrasts with the warmth of life that springs from the sea, even in the depths.
