A pact under the waves.

Niko arrives in the shallows, cold water curling around his blue tail. Ahead, an exiled prince braces himself aboard a narrow, warded boat against the incoming tide.

The prince is a young adult man with a lean build, wind-tangled black hair, and a weather-darkened blue cloak clasped over travel-worn armor. Pale runes flicker across the boat’s hull.

The ward shudders, shedding silver sparks into the brine. Beyond the boat, a dark shape glides beneath the rippling surface, circling just beyond the prince’s reach.

Another wave lifts the boat hard against its failing magical boundary. The unseen shape pauses below, while the runes dim one by one.

The exiled prince studies Niko through the rain and silver spray. For one breath, the failing runes cast his face in cold, ghostly light.

At his name, the dark shape beneath the boat circles once, and the ward’s scattered sparks draw together into a thin ring around the hull.

The ring steadies the boat against the tide. Beneath the surface, something pale turns toward Niko, then slips into the deeper blue.

The silver ring around the boat tightens, and the water between Niko and Caelan goes still. The ward listens as though the sea itself weighs the warning.

Caelan removes his cloak clasp, a small crown-shaped piece of dark pearl, and presses it against the ward. The runes flare, accepting his consent.

The binding answers, but its first toll leaves Niko’s magic noticeably drained. The pale shape below rises beneath the hull, and the ward settles into a firm blue glow.

Niko places his palm against the blue ward. Its magic pours through him as layered currents: Caelan’s oath at the center, tide-pressure outside, and a deliberate fracture threaded beneath the hull.

The divination succeeds, but the ward recoils through Niko’s hand. Frost-white numbness climbs his arm, and a measurable portion of his remaining magic gutters away.

Niko’s touch exposes the severing charm in the runes, a narrow black filament anchored beneath the hull. The blue ward now reveals its exact wound.

Below them, the pale shape circles into view again. The exposed filament pulses once in answer, and the boat’s ward brightens around Niko’s hand.

Niko gathers the ward’s blue radiance through his palm and guides it into Caelan’s oath-mark. Sea-light coils around the prince without breaking the binding.

The transformation completes in a breath. Caelan’s legs become a powerful blue-green tail, while the ward reshapes its recognition around his changed nature.

Caelan slips from the boat into the shallows, newly adapted to the water. The dark shape beneath the hull circles once, then retreats from the ward’s calm blue boundary.

Niko’s gaze lingers on Caelan’s new blue-green tail, its scales catching the ward-light. Warmth rises visibly to his cheeks despite the cold spray.

For a moment, the tide and failing runes seem quieter. Caelan looks down at his transformed body, then back toward Niko with startled amusement.

He tests the powerful sweep of his tail, sending a smooth ripple beneath the boat. The ward accepts his movement, its blue boundary widening toward the open channel.
