Chapter Text
The tide charts don't make sense.
Eric spreads them across his desk for the third time this week, comparing recorded measurements against what the fishermen are reporting. The numbers should align. They don't. High tide coming six hours early on Tuesday, three hours late on Thursday, not coming at all yesterday despite the moon phase demanding it.
He rubs his eyes, tastes salt on his lips from the harbor air still clinging to his skin. Outside his window, the sea sits flat and dark under a moonless sky. Calm. Deceptive.
His advisors want him to call in weather-workers, make offerings to sea gods, commission prayers from the coastal temples. Eric has been nodding through their suggestions while privately doing what actually works. He adjusts harbor schedules, redirects supply routes, meets with fishermen at dawn to track which waters are still viable and which have turned strange.
What matters, in the end, is that the kingdom functions.
Three years since Aerin left, and he’s learned how to govern without her. Wanting something and being suited for it aren’t the same thing. She wanted motion, exploration, the horizon always shifting ahead of her. He wanted roots. He wanted responsibility.
Neither of them failed. They just wanted different things.
He doesn't think about her often anymore. When he does, it's with relief more than grief. They would have made each other miserable eventually.
A knock at the door pulls his attention. His harbormaster has another report. Three fishing boats returned empty despite visible schools beneath the surface. The nets came up clean, like the fish had simply refused to be caught.
Eric pulls on his coat and follows the man down to the docks.
The water looks and sounds normal, heavy with salt and rot and life the way it always does. But when Eric crouches at the dock’s edge, trailing his fingers through the surface, something feels wrong. The temperature isn’t consistent. Patches of cold linger where they shouldn’t, even in summer waters.
He pulls his hand back, wiping it dry on his trousers.
One of the fishermen is explaining the phenomenon, words spilling faster than Eric can track them, something about cursed waters and angry gods. Eric half-listens, already knowing that panicked explanations rarely contain useful information.
“We adjust the routes,” he says when the man finally stops for breath. “Give these waters time to settle. Try the northern shelf instead.”
“But Your Highness, if the sea itself—”
“The sea has moods,” Eric says. “We work with them, not against them.”
The fishermen exchange looks. Eric knows what they're thinking. His practicality borders on disrespect when it comes to divine forces. Maybe. But his kingdom hasn't starved yet, so he'll keep making practical decisions until they stop working.
He's back at the harbor two days later when it happens.
Mid-afternoon. The sun is high enough to burn the back of his neck. He’s waist-deep in the shallows, helping Dmitri secure a listing skiff that’s taken on water faster than it should. The wind dies completely, the kind of stillness that makes his skin crawl.
The water temperature drops.
Not gradually, but all at once. Eric's legs go numb from the cold, breath catching in his chest. He straightens and looks down.
The water around him has gone dark. Not cloudy, but dark, like something vast is blocking the light from below.
His pulse kicks faster, but he doesn’t move or call out. He just stands there, hands loose at his sides, pressure building behind his sternum.
Something is watching him.
He knows it the way he knows when a storm is coming, when a horse is about to bolt, or when a negotiation is about to turn. His body understands before his mind catches up. There’s intelligence in the water, attention focused on him specifically, cataloging his response.
Eric holds still. He doesn’t retreat to shore or acknowledge the fishermen starting to notice the temperature drop, the unnatural darkness.
The presence lingers, as if considering.
Then it recedes, the water warming again as sunlight penetrates to the sandy bottom. The cold leaves his legs tingling, hypersensitive.
Dmitri is staring at him. “Your Highness? Are you—”
“Fine,” Eric says. His voice comes out steady. “Let's finish with the boat.”
He works through the rest of the afternoon with salt drying on his skin and awareness prickling between his shoulder blades. When he finally returns to the castle, he catches himself looking back at the water.
The sea looks calm, empty.
It doesn't feel empty.
That night he dreams of pressure, of being cataloged by something vast and waiting.
***
Triton has been watching the human prince for six months.
It started as anger. Aerin chose a human world over the sovereignty he'd offered her, chose motion over roots, and then the human she'd bound herself to, let her go without breaking. No grief spiral. No political collapse. No satisfying proof that mortals are too small, too fragile, too insufficient for the weight of what they claim to want.
Eric just governed.
Triton watched from the deep, expecting the inevitable fracture. Humans break, they always break. But Eric redirected trade routes when Triton sent storms, adjusted fishing schedules when Triton inverted migration patterns, and walked his coastline at dawn like a man accounting for every inch of territory he’s responsible for.
Triton saw competence without spectacle, leadership that didn’t demand recognition.
It should have been proof. Evidence that Aerin’s choice was doomed from the start, that humans are exactly as limited as Triton has always known them to be.
Instead, he found himself watching closer.
The human governs people the way Triton governs elemental forces. He rules by capacity, not command. Respect for limits. Strategic application of pressure. Eric doesn't fight the sea's interference. He adapts to it. Works with the moods Triton imposes rather than railing against forces he can't control.
Triton has been king of the sea for centuries. He's never encountered a human who operates at his level of competence in an entirely different arena.
The watching has become something he won't name.
Tonight he rises closer to the surface than he should. The moon is a sliver, the water dark enough that his bioluminescence barely registers. Eric is at the harbor again, always at the water, always alone at these hours.
Triton doesn’t surface or announce himself. He just hovers twenty feet down, tail moving in slow, restless coils, eyes adjusted to track the silhouette above.
Eric's standing at the dock's edge. His shoulders are broad and his posture upright, even in private. He's looking out at the horizon, but his body is oriented down, toward the water.
Toward Triton.
He knows, maybe not consciously, but his body registers the attention. Triton can see it in the tension along his spine, the way his weight shifts, the fact that he hasn't left despite the late hour and the cold wind coming off the water.
Triton's hands flex around his trident. He could surface and force a confrontation. Eric is in his waters, technically trespassing on sovereign territory every time he wades past the tide line.
Triton doesn't surface.
He just watches, cataloging the way Eric moves, how he thinks through problems, how much it would take to break his composure.
The human should have shattered by now. He should have crumbled under the weight of losing Aerin, of ruling alone, of the sea's increasing interference in his domain.
He didn't.
Triton sinks deeper, putting distance between himself and the surface, between himself and the human who keeps pulling his attention back.
Above, Eric stands at the harbor a moment longer. He turns, walking back toward the castle, steady and unhurried.
Triton stays in the deep, watching until the human's silhouette disappears.
The water around him agitates, current shifting without wind to drive it, his own restlessness made manifest.
He should leave Eric alone, let the human govern his small kingdom. He should stop interfering with tides and storms and fish migration. Stop watching.
He doesn't.
Three days later, he builds a storm.
