The Rise of Repatine

I used AI to do this so if you have any problem tell me in the comments section and I will do what I can. Thank you!
'Exegol, a dead world. Barren, dark, and cold. The sky was a perpetual shade of ash grey, the air heavy and still. The only sign of life, if one could call it that, was the massive monolithic citadel that towered above the desolate landscape, its obsidian spires piercing the sky like talons. This was the domain of the Sith, the seat of their power. It was here that Rey sought to confront the one they called Darth Sidious, Palpatine.
She had tracked him down to the depths of his lair, a labyrinthine chamber carved into the heart of the citadel. There, he sat upon his throne, his long, metallic arm attached to the backrest, his withered, ancient form hunched over. His eyes, once piercing and full of life, now glared out from sunken sockets, empty and full of malice.
Rey stood before him, her breath coming in ragged gasps, her fists clenched in anger. The air crackled with the dark energy that emanated from both of them. "You've taken everything from me," she hissed through gritted teeth. "Everyone I've ever loved. I won't let you have Kylo Ren too." 
With a primal scream, she launched herself at the ancient Sith Lord, her lightsaber slashing through the air. But Palpatine was faster, more cunning. He merely leaned back in his throne, the metallic arm moving with inhuman speed, blocking her every strike. They danced around each other, their weapons clashing, the sound echoing through the chamber like thunder. And then, in a moment of weakness, Rey saw her opening.
She leapt back, feinting to the left, before spinning and delivering a powerful blow to Palpatine's metallic arm. There was a shower of sparks and a sickening crunch as the ancient limb was severed from the Sith Lord's body. Palpatine's eyes widened in surprise, but it was too late. Before he could react, Rey raised her lightsaber high above her head and brought it down with all her might, cleaving him in two.
His essence, his dark and twisted soul, seemed to writhe and struggle before finally settling into her own. She felt it, the weight of his presence, the knowledge and power that came with it. It was overwhelming, intoxicating. And then, as if in some macabre mirror image, her face began to change. Her features shifted, contorted, until they were no longer her own. They became...Palpatine's.
With a sinister chuckle, she stood up, feeling the weight of the ancient Sith Lord's armor pressing down upon her. She looked down at the two halves of his body, still twitching and convulsing on the floor. "You're with me now," she said, her voice now deep and echoing with the power that was no longer hers, but his. "And together, we will poison the galaxy with evil."
And with that, Repatine of the Final Order turned and walked away from the twitching remains of the once-mighty Darth Sidious, her long, dark shadow stretching out before her as she disappeared into the labyrinthine depths of the citadel, ready to begin her new role in the Sith order. The dead world of Exegol held its breath, awaiting the coming of the end.
