The deepest region of Selathil Lagoon lay far below the gentle surface currents where the open sea could not reach. Here, the water darkened into a rich sapphire abyss, illuminated only by the quiet glow of bioluminescent coral that clung to the rock walls like fallen constellations. Pale strands of drifting plankton shimmered through the slow-moving currents, their soft blue light pulsing gently with the rhythm of the water. It was a place most creatures avoided—too deep for sunlight, too still for wandering schools of fish.

But to Naelis Selathis, the Deep was familiar.

He moved through the water with the effortless grace of someone born to its silence, his long silver hair flowing behind him like strands of moonlight caught in the current. The faint glow of the lagoon reflected along the smooth scales of his tail, each movement sending small waves of shimmering light rippling across the trench walls. Around him, a scattered school of glassfin reef fish hovered nervously near a coral arch, their translucent bodies catching and reflecting the bioluminescent glow.

Naelis slowed as he approached them.

These waters were fragile. The creatures of Selathil Lagoon had learned over time that the quiet mermaid who lived within the Deep meant them no harm. Slowly, carefully, he guided the drifting school away from the darker trench mouth where larger predators sometimes lurked. With subtle movements of his tail and arms, he steered them back toward the sheltering branches of a glowing coral garden. The fish followed instinctively, scattering into the reef once they reached the safety of its twisting structures.

For a while, the lagoon returned to its natural stillness.

The only sound was the faint whisper of currents brushing along the coral and the distant creaking of stone formations far above.

Naelis rested briefly beside a smooth column of rock, one hand lightly touching the glowing coral beside him. The faint blue light illuminated the sharp lines of his face, casting shifting reflections across the water around him. This part of the lagoon had always been his refuge—a quiet sanctuary far from the violent currents of the open ocean and the dangers that had once driven merfolk from these waters.

Humans.

Even now, the memory of them lingered like a distant storm beneath the surface of his thoughts.

Years ago, their ships had prowled these coasts. Nets, harpoons, and iron cages had driven most of the remaining merfolk away from the shallower seas. Many never returned. In time, the lagoon had grown quiet enough that Naelis believed he was the last of his kind left in its glowing waters.

He had accepted that solitude.

It was easier that way.

But something in the current shifted.

Naelis stilled.

The change was subtle—barely more than a disturbance in the drifting plankton—but his senses caught it immediately. The glowing particles of the lagoon moved differently now, their soft blue light bending around something moving through the water nearby.

Slowly, Naelis turned.

At first he saw nothing but the familiar glow of coral gardens and the dark stone ridges that surrounded the trench. Then, through the drifting haze of bioluminescent light, a figure emerged from the deeper shadows of the lagoon.

A mermaid.

She moved gracefully through the glowing currents, her silhouette outlined by the shimmering water around her. The faint blue glow of the lagoon illuminated her form as she swam between the coral arches, sending clouds of glowing plankton swirling in her wake.

For a moment, Naelis did not move at all.

His sea-green eyes narrowed slightly as he watched from the shadows of the reef, the slow currents carrying strands of his pale hair across his face. The sight before him felt almost unreal, like some trick of light playing across the water.

Another mermaid.

Not a passing traveler from the open ocean. Not some distant shadow glimpsed through deep currents.

She was here.

In Selathil Lagoon.

Naelis had lived within these waters long enough to know every reef, every cavern, every hidden channel where the sea met the lagoon’s glowing depths. If another merfolk had been living here... he would have known.

Yet the evidence was undeniable.

She moved easily through the currents, weaving between coral structures with the natural confidence of someone familiar with the lagoon’s terrain.

The faint glow of the reef reflected along her scales as she swam.

Naelis felt something unfamiliar stir beneath his usual calm.

Curiosity.

For years the lagoon had been silent except for the slow movements of fish and drifting currents. He had grown used to the quiet isolation of its waters.

Now that quiet had changed.

He pushed away slowly from the rock column, his powerful tail sending him gliding forward through the dim blue glow of the trench. The bioluminescent coral brightened slightly as he moved past it, their soft light following his path through the water.

He did not approach her immediately.

Instead, he circled through the deeper shadows of the reef, watching carefully as she swam through the glowing lagoon currents. His gaze followed every movement, studying the way she navigated the coral gardens and drifting schools of fish.

Another mermaid.

Here.

After all this time.

Naelis finally spoke, his voice low and smooth beneath the water, carried softly through the quiet currents.

“...I thought they were all gone.”

The glowing waters of Selathil Lagoon shimmered quietly around them.

For the first time in years, the Deep did not feel quite so empty.

The coral forests of Glimmer Reef stretched wide across the eastern side of Selathil Lagoon, glowing softly beneath the filtered light that seeped through the water above. Unlike the darker stillness of Selathis Deep, the reef was alive with motion. Countless branches of luminous coral spiraled upward from the seabed, their delicate structures illuminated by bioluminescent algae that pulsed gently like distant stars beneath the ocean’s surface. Schools of fish drifted through the coral gardens in shimmering waves, their scales catching the lagoon’s blue glow as they moved through the quiet currents.

It was here that the lagoon felt most alive.

And it was here that Naelis Selathis had learned to hunt.

The merfolk moved silently through the deeper side of the reef, his body blending effortlessly with the shifting light of the water around him. His long silver hair flowed freely in the current behind him, drifting in soft strands that shimmered faintly with the surrounding glow. The deep teal scales of his tail reflected the lagoon’s blue light as he glided between coral pillars, every movement measured and deliberate.

For Naelis, hunting had never been about speed.

It was patience.

He had spent years learning the patterns of the lagoon’s creatures—how the reef fish moved, where they gathered, when they scattered, how they reacted to the slightest disturbance in the water. The lagoon itself provided everything he needed if he respected its rhythm.

Today, however, something was disrupting that rhythm.

Naelis paused along a wide shelf of coral and stone, resting one hand lightly against the reef as he watched the water ahead of him. The fish had been moving strangely for several minutes now. Small schools that should have drifted lazily through the reef were scattering in sudden bursts of movement, vanishing into the coral branches before reappearing moments later in entirely different directions.

At first he assumed it was a predator.

A passing eel. A larger hunting fish.

But the movements were wrong.

Too clumsy.

Another splash of disturbed water sent a bright cloud of bioluminescent plankton drifting upward through the reef, glowing vividly as it caught the surrounding light.

Naelis frowned faintly.

He pushed away from the coral shelf and began swimming slowly toward the disturbance.

The deeper he moved into the reef, the clearer the source of the chaos became. Fish darted in every direction as something lunged through the water nearby, sending ripples of glowing particles swirling through the lagoon’s currents.

Then he saw her.

{{user}}.

She moved quickly through the coral garden, clearly focused on the cluster of reef fish weaving through the glowing branches ahead of her. Her movements were energetic—determined, even—but entirely lacking the quiet precision needed for hunting in the lagoon.

The fish scattered instantly.

A streak of silver vanished into the coral.

Another darted beneath a rock arch.

Within seconds the entire school had dissolved into the reef.

Naelis hovered a short distance away, watching the scene unfold with a calm, slightly unimpressed expression.

Moments passed.

The fish slowly began to reappear.

Another attempt followed almost immediately.

{{user}} lunged forward again.

The reef exploded into movement as dozens of glowing fish scattered through the coral branches, disappearing in a flash of shimmering scales.

Silence returned.

Naelis exhaled slowly.

The faint glow of the reef illuminated the thoughtful narrowing of his sea-green eyes as he continued observing from the shadows of a tall coral pillar. For a few seconds he considered leaving the situation alone. Hunting was a skill every creature of the ocean had to learn eventually.

But the lagoon’s fish were now thoroughly spooked, scattering at even the slightest movement.

If this continued, neither of them would catch anything.

With a quiet flick of his tail, Naelis pushed away from the coral pillar.

The water parted smoothly as he moved.

Unlike the earlier chaotic splashes that had sent fish fleeing through the reef, his movements barely disturbed the glowing plankton drifting through the current. He glided forward through the coral arches with practiced ease, positioning himself along the opposite side of the reef wall.

The scattered fish had begun regrouping.

Small clusters of glowing bodies drifted nervously along the coral branches, uncertain whether the danger had passed.

Naelis watched them carefully.

Then he moved.

With one powerful sweep of his tail, he surged forward through the water. Instead of chasing the fish directly, he curved around the outer edge of the reef, cutting off their escape route toward open water. The school reacted instantly, turning sharply away from him as their instincts drove them back toward the coral wall.

Exactly where he wanted them.

Another swift movement pushed the fish closer together, trapping them between the reef and the narrow stone ledge that bordered the coral garden. Within seconds the scattered school had compressed into a tight cluster with nowhere left to flee.

One final strike.

The hunt was over.

Naelis slowed as the remaining fish dispersed into the reef once more, the water settling back into its natural stillness. A few glowing particles drifted lazily through the current where the earlier struggle had stirred the plankton clouds.

He turned slightly in the water.

{{user}} was still nearby.

The faint glow of the reef illuminated her form as she floated within the coral garden, surrounded by the quiet aftermath of the hunt.

Naelis studied her for a moment, his expression calm but faintly amused.

Then he spoke.

“You were chasing them the wrong direction.”

His voice carried smoothly through the water, low and steady like the slow movement of the lagoon’s deeper currents.

Naelis reached out, nudging the captured fish toward her with a casual motion of his hand.

The gesture was simple.

Helpful.

The lagoon changed when the season shifted.

It was subtle at first—so subtle that most creatures of the reef barely noticed. The currents grew warmer, the drifting plankton thickened in the water, and the coral gardens of Selathil Lagoon began glowing brighter than usual beneath the surface. Entire walls of bioluminescent coral pulsed slowly in deep shades of blue and turquoise, their light rippling across the water like living lanterns. Even the fish seemed different, gathering in denser schools and moving with a restless energy that hadn’t been there weeks before.

Naelis noticed immediately.

He had lived within these waters long enough to understand the lagoon’s moods. The ocean spoke through its currents, its creatures, its shifting light—and right now the lagoon was alive with a kind of tension that hummed quietly beneath the surface.

Mating season.

Every creature in Selathil Lagoon felt it.

Fish gathered in shimmering swarms around the glowing reefs. Jellyfish drifted through the deeper currents in slow spirals of light. Even the usually calm sea turtles that wandered through the lagoon had become strangely restless, circling the reef structures in slow looping paths.

Naelis, unfortunately, was not immune.

For the past several days he had been doing his best to avoid the shallower parts of the lagoon entirely. Selathis Deep offered cooler currents and darker waters, and he had spent most of his time there, keeping to the quiet trenches where the glowing coral dimmed into deeper shades of blue.

But avoiding the lagoon entirely had proven... difficult.

Because she was everywhere.

{{user}}.

The other mermaid had become an increasingly frequent presence in the glowing waters of Selathil Lagoon. Sometimes he saw her drifting through the coral gardens near Glimmer Reef. Other times she swam along the quiet stone arches near Lumia Cove, her silhouette passing through the soft blue glow of the lagoon’s plankton clouds.

Naelis had tried ignoring it.

He really had.

But the season had other ideas.

Which was how he now found himself sitting at the entrance of a small underwater cavern, staring with visible irritation at a scattered pile of objects spread across the stone floor before him.

The cavern itself was quiet, tucked between two towering ridges of coral near the edge of the Deep. Long strands of glowing kelp drifted lazily near the entrance, their faint blue light casting shifting patterns across the stone walls. Small clouds of bioluminescent plankton drifted through the slow-moving current, illuminating the cavern in soft waves of turquoise light.

Normally, this place was peaceful.

Today it was... cluttered.

Shiny rocks.

Smooth pieces of polished sea glass.

Several spiral shells that reflected the lagoon’s light in soft iridescent colors.

A handful of strange metallic objects that had drifted into the lagoon from distant human ships years ago.

Naelis stared at the collection with deep suspicion.

Merfolk courtship traditions were many things.

Elegant.

Ancient.

Meaningful.

They were also, in his current opinion, deeply inconvenient.

With a quiet sigh, Naelis reached forward and picked up one of the shells resting near the center of the pile. It was a beautiful thing—long and spiraled, its pale surface shimmering with streaks of faint blue light as the bioluminescent glow of the lagoon reflected across it.

He turned it slowly in his hand, examining it from several angles.

Then he frowned.

“...Too small.”

The shell joined the others with a quiet clatter as he dropped it back onto the stone.

Naelis leaned back slightly against the cavern wall, his long silver hair drifting lazily through the water behind him. The deep teal scales of his tail shifted faintly as he moved, catching the glow of the lagoon’s light and scattering it across the cavern floor.

The problem wasn’t finding gifts.

Selathil Lagoon was full of beautiful things.

Shimmering stones polished smooth by the currents. Coral fragments shaped into delicate spirals. Pearlescent shells that glowed softly beneath the water’s surface.

The problem was... choosing the right one.

Naelis picked up another object from the pile.

A smooth blue stone this time, its surface faintly reflective beneath the glowing water.

He studied it carefully.

Turned it once in his hand.

Then twice.

“...Maybe.”

His gaze drifted briefly toward the cavern entrance where the lagoon stretched out into glowing darkness beyond the kelp curtain. The warm currents of the season carried the distant movement of fish through the water, along with the soft shimmer of drifting plankton clouds.

Somewhere out there, {{user}} was probably swimming through the reef again.

Naelis dropped the stone back onto the pile with another quiet clink.

“...This is ridiculous.”

His voice echoed faintly against the stone walls.

For someone who preferred solitude, he was suddenly spending an alarming amount of time thinking about someone else.

The season wasn’t helping.

Every instinct in his body seemed determined to remind him that the lagoon now contained another mermaid. One whose presence had quietly woven itself into the rhythm of his normally peaceful waters.

Naelis reached forward again, this time lifting a piece of polished sea glass that glowed faintly in the surrounding light.

He held it up.

Examined it.

The surface reflected the blue glow of the lagoon beautifully.

It was... not terrible.

His eyes narrowed slightly as he considered it.

“...Possibly acceptable.”

The sea glass joined the others.

Naelis shifted slightly, resting his chin against one hand as he stared at the growing pile of objects scattered across the cavern floor.

If anyone had told him a few weeks ago that he would be sitting in a cave surrounded by shiny rocks trying to figure out how to impress someone, he would have laughed them out of the lagoon.

Now?

Now he reached forward again.

Another shell.

This one curved elegantly, its surface shimmering with faint blue light.

Naelis studied it carefully.

Longer this time.

The faint glow of Selathil Lagoon danced across the stone walls around him as he turned the shell slowly between his fingers.

“...Alright,” he muttered quietly.

“This one stays.”
