Amaya grunted as she was lifted in the air, the motion of Cecilia's fingers shifting her like a marionette.
"What are you doing? Let me go!" She demanded. She could feel the unknown influence invading her, taking control, but was powerless to do anything about it.
Cecilia smiled.
"I am giving you a gift, free of charge. Just because you are so... fascinating."
She curled her fingers, the threads of destiny tightening in her grip.
Her influence was seeking an outlet, and soon found it. For generations, Amaya's clan had lived in a secluded valley, high up on the mountains of Fuaxhu. The country had been well known for its arts, culture and martial prowess, but a more mysterious and almost mythical part of it had been its elite stealth operatives, the ninja. Spies and assassins, they were famed for their skills in battle and prowess in staying undetected. And of them, Clan Duskrain had been especially notorious thanks to their magic.
But all things must come to an end, and after numerous civil conflicts many aspects of Fuaxhu's culture faded into obscurity generations before their fall, the ninja among them.
Until now, when that long forgotten potential was being brought forth once again, a wilted flower blossoming into a deadly nightshade.
Amaya gasped as her muscles tightened, the lean fibers strengthening bit by bit under Cecilia's influence. Bones started popping as she stretched taller, her school uniform starting to strain. Her hands opened and closed on their own, the tendons renewed as brand new muscle memory trained its way into her.
"I don't... understand. Ugh!" She grunted as her biceps swelled.
"I don't need you to understand. Just be a good little pawn and let me work. I'm sure you'll love the results." Cecilia dismissed her. Another hand had joined the work now, and she found herself actually starting to enjoy twisting the girl into a new form more befitting of her purposes.
Amaya's core rumbled as abs pushed their way to the surface. Soon a six pack adorned her stomach, and in her mind's eye she could see the rippling womanly musculature undulating as she dove out of the way of an attack from a practice dummy.
"My mind... it's..." she managed before it hit her in full force, her mental image being rewired, intensive training pumped in. Her lengthening fingers grew proficient in handling all sorts of weaponry, her footwork becoming almost unnatural as her leg muscles were engorged. Lean but strong, agile but powerful, womanly but unmatched. Her body was developing into a perfect predator.
But her physical enhancements were nothing compared to the magical ones. Her burgeoning talent with illusions exploded as a fraction of Cecilia's overwhelming magical power entered her. Within seconds, becoming invisible was as easy to her as breathing, but it didn't stop there. She could change her appearance, manipulate noise, become intangible, climb up walls, walk on water. The ancient arts of her clan were awakening as darkness became her new home, allowing her to project it to conceal herself and extinguish the magic of others, and even meld into it and travel in shadows. Soon she would be truly reborn as a Duskrain Shadow Dancer, the highest calibre of ninja in history.
Cecilia observed her creation as she neared completion. She had been positively surprised to find herself enjoying the process of twisting an unassuming girl into a powerful servant. She suspected the influence of the pond might have been at work, but gave it no thought. With a final flourish of her hands she pulled the strings, disentangling Amaya and letting the rest of the changes cascade in.
She screamed as Cecilia's masterstroke coursed through her, a final burst of strength filling Amaya as bones snapped into their new, more adult configuration. Her spine curved to present her chest and backside, nonexistent breasts drinking in fat as they bounced into existence as solid B-cups, manageable handfuls that wouldn't hinder her movement.
Her bottom clearly didn't get the memo as it engorged with copious amounts of fat, her hips angling and cracking into a childbearing configuration as her buttocks swelled and thighs grew with muscle, a heart-shaped ass leading into luscious tree trunks that could kick a man's head off. Her whole body undulated as strategic fat rounded out her form to conceal the strength within, leaving her looking womanly and weak but stronger than most men underneath. Under Cecilia's amused watch she multiplied, her powers peaking as she manifested countless copies of herself, hundreds of Amayas populating the courtyard, all of them simulating her orgasmic thrashing as she achieved perfection, the darkness leaking out coloring her pupils pure black and lengthening her raven hair, a pitch-black hair tie tying it into a shoulder-length ponytail. The shadows leaking out of her consumed her tattered school uniform, leaving brand new clothes in their place. Her new womanly form was encased in a fishnet bodystocking, a midnight blue vest and pants covering her modesty as a black bandana covered her mouth, completing the new shadow dancer.
Cecilia let go of her threads and allowed her newest acquisition to regain her bearings.
Amaya breathed heavily, the hundreds of other Amayas following suit. She could clearly feel each and every one of her doubles, the control over her powers perfect. She allowed all the illusions to melt into shadows that coalesced around her, forming into a short, single-edged sword that fit her grip perfectly.
She holstered her new weapon and took a knee, bowing before the floating sorceress who had empowered her.
"Mistress, I thank you for this gift. You have given me new purpose, new hope in life. I pledge myself to your service."
Cecilia was pleased with how her little test turned out. Even without her conscious demand, Amaya was now a loyal servant ready to follow her every order. Of course she had no need for help of any kind, but who knew? This could prove even more amusing than anticipated.
"My Shadow. Your loyalty is appreciated, however unnecessary it may be. But I do have a new plan in the works already..."
