Leena's first days aboard the Flying Dutchman were a torment. Accustomed to deception and manipulation, she was not ready for the relentless labor and the never-ending torture of the sea's wrath. The crew took a perverse pleasure in her struggles, as she had no power or art of persuasion over these forsaken souls.

Days blended into nights, and weeks into months. The relentless weight of the sea and the perpetual damp started to change Leena. The youthful, albeit deceitful, skin began to show signs of decay, her eyes dulled, and her once nimble fingers started to grow webbed and clammy.

The very fabric of her being began to intertwine with the sea. Barnacles began to sprout from her arms and legs, her hair took on a seaweed-like texture, turning a deep green and clinging wetly to her back. Her once sharp and conniving eyes began to glaze over with a blueish hue, as if the very abyss Davy Jones spoke of was consuming her from the inside.

Yet, within these changes, there was a metamorphosis of her spirit. Initially, the crew enjoyed tormenting the "little girl" who tried to deceive them with her tales. But as the sea began to claim her, making her one with its depths, they started noticing a certain fierceness in her. The deceptive little Esther was shedding her skin, and in her place, a formidable and resilient Leena was emerging.

As she lost her humanity, Leena became an adept sailor. She was entrusted with tasks that required precision and agility. Her new form, crafted by the sea, allowed her to slip through tight spaces and hold her breath for lengths of time that were inconceivable to her past self.

But the sea didn't just grant her physical prowess; it also sharpened her mind. The isolation of her servitude and the constant menace of her surroundings made Leena's cunning and wits crucial for her survival. She began to manipulate situations aboard the ship, subtly pitting crew members against one another, playing them as she had once played innocent families.

Years passed. Leena's reputation grew. Many feared her, others respected her, and some even sought her counsel. Rumors spread that she had become Davy Jones's confidante, but Leena never confirmed nor denied such tales.

Yet, even as she transformed into this powerful, sea-claimed entity, a remnant of humanity lingered within her. Occasionally, she would gaze over the vast expanse of the ocean, and a lone tear would roll down her decaying cheek. The tear would always fall into the sea, lost amidst the waves, much like the remnants of her former self.

Over time, Leena's ambitions grew. Would she be content to serve for a mere century, or did she aspire for something more? Only the vast and mysterious sea held the answer. And as the waves whispered their secrets to her, Leena listened intently, ready to shape her own fate once again.
