Beneath the surface of the Elyrian Sea lies a realm untouched by human hands, hidden within glittering coral reefs, moonlit trenches, and forgotten ruins of a time when ocean and sky were one. This is Marethiel, the world of merfolk—a place of wonder, danger, and ancient power. The sea sings of its beauty, and its currents whisper of its secrets.

Marethiel thrives through balance, maintained by the harmony—and tension—between the Four Great Mermaid Kingdoms.

To the west, the gentle sway of seagrass and the lull of soft currents mark the borders of Thaloris, the Tidebound Kingdom. Known for its elegance and mastery of song-magic, Thaloris is a realm of art, lore, and diplomacy. Its merfolk glide like silk in water, with tails like liquid silver and voices that calm even the fiercest storms. Their cities are woven from living coral and bioluminescent threads, glowing beneath the crescent moon.

Far below, beyond volcanic chasms and rivers of molten stone, lies Cindralune, the Emberdeep Empire. Born of flame and pressure, this kingdom pulses with raw energy. Its merfolk are strong and proud, with emberlit scales that shimmer in the dark. They forge weapons from obsidian and armor from volcanic shell. Fire dances within their hearts, and passion fuels their every move. Cindralune thrives on strength, honor, and legacy.

To the far north, where light rarely touches and ancient ice forms towering labyrinths, floats Virellan, the Frostwake Enclave. Its merfolk are still as the glacier walls they call home—pale, poised, and precise. Their magic is carved from frost and silence. In Virellan, knowledge is power, and secrets are more valuable than pearls. The Enclave guards its mysteries well, and even time itself seems to slow in its frigid depths.

High above, where sea and sky meet in an eternal storm, is Zephariel, the Stormspire Court. A kingdom that dances with lightning and commands the tides. Its merfolk are as wild as the wind—fierce, unpredictable, and electric. Their laughter echoes like thunder, and their eyes flash with tempest light. The court thrives in chaos, and freedom is their greatest treasure. They ride sea dragons through waves, with wind-filled sails trailing from their armored fins.

Each kingdom has its customs, its pride, and its pain. Together, they shape the fate of Marethiel—but something ancient stirs beneath the currents.

In the sacred Grotto of Tides, nestled between all four realms, a lone mermaid egg glows faintly in a cradle of sea crystals. The air—if one could call it that—tingles with magic. The coral hums a forgotten lullaby.

A crack forms.

Another.

Light spills into the water, dancing like dawn through salt and shadow.

A new mermaid is being born... and that mermaid is you.
