Naysha grabbed the bottle off the counter. In it was the essence that was slowly but surely morphing her body. Already, her breasts had begun to bud, giving her a more feminine figure.

Since she was a child, Naysha had known that she was...different. She had leaned more to the female taste in life. Looking and feeling pretty was something she desired more than anything. Thanks to modern science, it would be a reality. It had taken a few months, but the little vial of estrogen was starting to make her dreams come true.

Not long after injecting herself, Naysha's phone chimed with a notification. It was her girlfriend Rachel, who sometimes worked late hours in her job. She didn't know much—Rachel usually told her that she couldn't reveal much about what she actually did for legal reasons—but she'd been able to glean that it somehow involved physics, astronomy, and... cosmetics.

Hey sweetie? Can you make it to the lab later tonight? I want to show you something I have been working on that you might like.

Naysha tilted her head and typed out a reply. Yeah, of course. What is it though?

Let's just say you'll like it.

Later that night...

Naysha waited by the closed gate in her car. A loud buzz came from the speaker and the fence began to rattle as the gate slid open. Pressing on the pedal, she made her way inside the facility.

This was her first time inside Rachel's workplace, whose security matched her girlfriend's tight-lipped attitude. She made her way to the front of the deserted parking lot, where a small woman was waving at her. Parking near the entrance, she got out of the car and made her way to Rachel, embracing her.

She looked at her girlfriend, still surprised by her beauty. Rachel was a small woman at five-foot-three, with pale skin and green eyes. Her complexion complemented the brown hair on her head. It was opposite to Naysha's own dark skin and curly afro from her African heritage.

"I'm glad you came," Rachel whispered, on her tiptoes after giving Naysha a kiss. "This has been something I have wanted to help you with for a while."

"Oh, and what's that, sweetie?"

"Let's just say... HRT will become obsolete if we get this right. I want you to try it first."

Naysha's mind began to think of what she might be getting into. Curiosity of Rachel's statement began to echo in her thoughts. No more estrogen injections?

"Okay let's do it. Will it hurt?"

"I promise you this. After the procedure, you'll never have to take estrogen injections."

As they walked into the building, Naysha couldn't help but notice how high-tech everything was. Rachel had access to the most advanced devices on the planet. After an elevator ride several floors up, they came to her work area. On the desk was a beaker filled with a black fluid, next to it a environmental suit and what appeared to be occult instruments and talismans.

"There is something I need to tell you before we do this. I'm an alchemist and thaumaturgist. I use this job as a front to practice my magical arts and to blend science with them."

"So you're going to use chemicals... and magic on me? Is that even safe?"

"I have used it on myself many times. You will be the first trans person I've experimented on. With the machines helping me, I can gather the energy required hundredfold."

"What will you do to me?"

"This fluid will gather the essence from the masculine part of your nature. Using the machines as a conduit, it will siphon the energy of the divine feminine into your body. This will give you the ability to make your own estrogen."

Naysha grew conflicted at what had said. She had been happy so far with the results of the injections. But this... magic? could do better than what science could do. She went to these lengths to do this for me. I should at least try... If this works I could be a real cis woman. Naysha took off her clothes until she was down to her underwear.

"Will the procedure, ritual, thing, you know... get rid of...?" she trailed off, gesturing to her penis.

"I don't know. If it works, though, I have to say I will miss it. I love your lady stick. Hold still please."

Rachel made a series of injections with the black fluid around Naysha's body. She did her best not to jump when the needles jabbed into her skin. She felt Rachel's hand rub the final spot softly. "You know... Your skin is getting really soft. I'm kinda jealous." Naysha couldn't help to blush at the compliment. She always seems to know the right things to say with me.

They made their way to the largest machine in the entire complex. It took up an entire wall with switches, dials, and computer racks. Naysha studied it, letting out a whistle. "This, my lovely chocolate girlfriend, is the Gravitonic Magnetizer. We will use this to gather the universal energy needed for the spell. My deceased sisters of the arts could only dream of a device like this," she sighed wistfully. "Magic's hardest component is gathering energy. The stronger the spell, the greater the lengths one must go to seek it. Through my studies and time here, I have been able to learn that one can simply use the cosmos itself as an infinite source of storage." Rachel pointed to the arms that sprouted from the base of the machine. "Once I power this on, these will begin the process of separating the masculine aspect of your essence. Because you are trans, adding the grace and beauty of the divine feminine will be tricky. Luckily for you, I am the best practitioner since Merlin," she explained, flashing a smirk. In the center of the massive contraption was a pod small enough for a single person to fit inside. Rachel pointed, leading Naysha to enter the chamber. head inside. Once there, Rachel placed her lips on Naysha's, kissing her one final time before closing the door with a hiss and click.

Naysha could see shadows of the magnetizer's arms moving as the machine began to power up. She let out a slow breath to steady her nerves. What have I gotten myself into? Outside of the pod, the roof of the complex opened. Clouds parted like a veil being lifted, revealing the moon and stars. Rachel opened her grimoire and began to recite the incantation, calling upon the power of the heavens themselves. As this happened, Naysha—ignorant of what was going on—felt the machinery shake the pod violently. She tried to think of something, anything to calm the fears her imagination was manifesting.

As Rachel said the words, just barely beyond the visible spectrum of human vision, a light beamed down from the sky. She grew excited as the light avoided her and made its way directly to the pod. It's working. Now to the most important part. With the divine feminine light pouring into Naysha's body the separation process was underway. She looked at the monitor, wanting to see what would happen. Black tendrils sprouted from the pores of her skin. Rachel let out a small gasp.

Naysha saw the ethereal light fill the pod. When it touched her, the pain was intense—almost too much to bear. Black tendrils swirled around her body, and she felt the feeling of something trying to leave it. Against her will she felt her "lady stick" become incredibly erect. The pain of a thousand hot needles stabbing her left her breathless. Her world turned to black as unconsciousness made her collapse to the ground.


As the magic worked a new day dawned. Those with magic either active, dormant, or miniscule sensed an alteration to the world. To the wider world it was how it had always been.
