The high tower containing Marlin's lab, was largely isolated from the rest of the palace. Both by design, and by coincidence. The magician's reputation was fiery, and fearsome, and nobody wanted to be risk offending him, nor risking his influence with the king.
The times where an explosion would rock that tower to it's roots, or when billowing clouds of unnatural colours and odours would escape meant, that few visited the him, and fewer wanted to visit him. Even when he wandered the corridors and passages of the rest of the palace, he had a distant look to his eyes, and frequently spoke to himself. The chambermaids and cooks recognised the herbs he collected from the forest when they were poisonous. The guards heard the deafening roar of his magic, and upon investigation, would find mass destruction, or worse left behind.
Despite his reputation, and abilities, the King considered him kindly and wise. Both men were fiercely loyal to each other. The gossip around the court told one particular story frequently, especially as it was so well witnessed.
The day one of the sculllery boys, whose normal work left them buried in the kitchen scrubbing pots and pans. Little Jack was waiting to surprise his love, one of the palace maids. In his exuberance, he leapt out from behind one of the suits of armours, and groped his true love. His hands roaming her body, squeezing her breasts, and sliding between her legs.
The shriek of outrage drew the guards, and as his true love turned around.... Well, it turned out to be Princess Fia, who landed a resounding slap on his startled face, and stuttering apology. When Fia drew a knife to defend herself, her honour, Jack twisted the knife from her hand and fled.
However, within a week, Fia had found a new Lady in Waiting, a youngish girl, though well-developed for her age. Initially she had a reputation for endless sobbing, and mournful looks. Even her clothes seemed to set her on edge, some dismissed it as the fickle emotions of youth. Jasmine however, positively flinched and cowered at the shuffling sound of the wizard's feet on the uneven stone floor of the castle. Not that rare a reaction, but there was a hint in her eyes, and from a certain angle, and in some lights, the vaguest hint of a scullery boy could be made out.

In Marlin's lab the glassware was clinking and chiming, as the wizard worked on a new infusion. It was a joyous opportunity, a chance to celebrate the upcoming meeting of Princess Fia and her suitor, Prince Kelos. The hope was this would secure the alliance between the two powers, and bring peace and prosperity.
Putting down the beaker, he went over to the cauldron, the contents brewed and stewed with a heavy slow bubbling certainty. Cautiously sniffing the brew, he nodded approvingly. Soon the perfection potion would be ready, a chance to further cement their love, and bring an abiding peace.
With a toast, both Fia and Kelos would take the potion, and their imperfections and past wounds be wiped away. Skin refreshed, features tweaked and improved. Not so much as to destroy their original proportions, but just to improve their pleasing symmetry.
Raising one hand in an imaginary toast to the happy couple, he failed to spot when the sleeve caught one of the test-tubes on the nearby table. Only when it shattered on the floor did he notice. A swirling cloud of emerald green rising, as the contents evaporated. It danced in the air, at moments moving against the air. Sparkles lighting it from within. Even Marlin wasn't quick enough, before it darted, like an insect and rose towards his face, his nostrils before sinking deep into his lungs.
Marlin fell to his knees, coughs racking his body. Each one scratchy, each one rising in pitch. Marlin's whole body rattled and rocked with each cough, as if trying to break his spine. He tried to talk, to mouth an incantation. He knew the potion he'd knocked over, knew it's consequences. Dread filled his heart, as he felt his clothes becoming baggier on his body, his hands retreating up his sleeves. He felt what few muscles he had winnowed away to softer, rounder flesh.
Kneeling on hands and knees, he coughed as if he were throwing up his lungs, and then stopped. The changes complete, finally able to breathe easily once more, he rocked back onto his heels. He felt his bum press against his feet, both wider and plusher than before. Marlin knew what this extra padding meant, he felt also the shifting weight on his chest. His spine was tickled by a long mane of hair, from his previously rather sparsely covered head. Dreading the discovery and the uncertainty, he explored his face. His hands discovering the extra plush lips, fixed in a permanent pout, not wide, but inviting, a mouth made for one thing, made for teasing and relieving men's aches and needs. Even the hand doing the exploring was slender and fine, long enough to encircle a man... where it matters most.
Her cheeks burning, she confirmed she truly was a woman, her elbows crashing against her wider hips, in the rush. She withdrew her hands just as quickly, as if afraid of catching something from her new delightfully feminine crotch.
"Shit, shit, shit."
Marlin cursed high and sweetly, her voice perfected for seduction, rather than cursing, or expressions of outrage.
