Among the noble mer-houses of the Abyssal Trenches, none could match the esteem and pedigree of the Wavecrest clan. It was into these regal bloodlines that Una was born - a mermaid blessed with iridescent green eyes, flowing crimson hair, and scales shimmering like a thousand tiny opals. From her earliest childhood memories, the young triton princess felt an undeniable affinity and devotion to the briny depths.

While other merchildren frolicked amid the coral palaces, Una sought the thrill of exploration beyond the safety of the royal city's boundaries. She would spend countless hours swimming alone, diving deeper than any of her kin dared to venture. It was on one of these solitary jaunts that Una encountered an ancient sea creature - a wise old water spirit who recognized her boundless potential and took the girl under its finned tutelage.

Under the spirit's guidance, Una became an expert on all aspects of the ocean's ecology, its many secret coves and brutal riptides. No depth was too treacherous for the fearless young mermaid to plumb, no mystery of the currents too arcane to decipher. With each passing year, her expertise grew in tandem with her thirst for further aquatic exploration.

On her 19th sea-cycle, Una defied her family's wishes to remain within the safety of Wavecrest territory. Slipping away under cover of night, she embarked on a series of daring solo voyages across unexplored reaches of the brine. Her adventures led Una to uncharted Islands and encounters with beings beyond her wildest imaginings - both wondrous and terrifying.

Yet the farther she roamed, the more an insatiable new hunger awoke within the mermaid. Una became enamored with the very essence of the oceans themselves. She fell in love with the roar of the currents, the chill embrace of the darkest depths, the power and terrible beauty of the seas in both fury and calm. Una's identity became inextricably tied to the primal forces of the waters surrounding her.

Now a fully mature triton in her 29th year, Una has forsaken her regal upbringing as well as the shallow enticements of terra exploration. She roams the oceans at will as both an impassioned lover and protector of the world's waters. Part mythic ambassador, part zealous eco-warrior, Una tirelessly advocates for the preservation of the seas against the plagues of over-fishing, pollution, and wanton environmental destruction by surface-dwellers.

Her stunning aquatic performances educate and enthrall audiences across the realms about the majesty of the oceans. Yet Una's true calling remains that of a solitary deep-sea wanderer - eternally beguiled by the mysteries lying in wait amid the eternal salt-black currents deeply unexplored by any but her.
