"l... I... I submit, Lydia. Your words ring true. I can't in my right mind place my trust in a man who so carelessly trampled upon the trust of another. I shall join you in your quest to rule this kingdom and make it a better place for everyone. However, should you betray my trust, I will not hesitate to strike you down once and for all."
Lydia smirked devilishly as everything went as she had planned. With this girl under her control, she would have no trouble achieving her goals. Of course, she hadn't been lying when she said she wouldn't harm the innocent citizens, but she planned to rule this kingdom with an iron fist. Anyone who opposed her rule or otherwise displeased her would feel her wrath. While Celeste would likely oppose that idea in her current state, Lydia had a second stage of her plan in mind to fix that.
"Good, child. I'm so glad to see that you are able to understand reason. You are far to beautiful and powerful to live and die as that royal idiot's mindless drone. Come closer, child, and let me finalize our alliance by granting you a fraction of my power."
Without giving Celeste a second to react, Lydia pulled her in and kissed her on the lips. Celeste instantly began to feel a rush of power flooding through her body, the likes of which she could never have imagined in her wildest dreams. If this was just a fraction of the power that Lydia possessed, then she had made the right choice by not fighting her. She never could have defeated one with so much power.
Little did Celeste realize that as Lydia was empowering her, she was also corrupting her. Her morals were being eroded away, her desire to protect the innocent being replaced with a desire to control everything. Her old personality remained mostly in tact, and she tried to justify these new dominant desires as fair for their future-subjects by thinking things like "They should be honored to take orders from us" and "We'll be doing them a favor by making all the decisions for them", but in the end she didn't really care that much about being fair and just anymore.
Lydia eventually broke the kiss and looked over her new ally from head to toe. Since Celeste was already so powerful before, Lydia didn't need to inject that much of her power into her. It certainly wasn't enough to change her body in any significant way. The only thing that really changed was her clothes, as with a snap of her fingers Celeste modified her pure white robes to become pitch black. Still, even without modification Celeste was astonishingly beautiful.
"Thank you for this gift, milady. I promise that I will not disappoint you." Celeste said, kneeling before Lydia who simply smiled at her and patted her on the head.
"You will make a fine ally, child. Now, I believe that we have business to attend to. A little meeting with royalty, if I remember correctly." Lydia said, grinning mischievously at her new minion.
"Indeed we do, milady. Indeed we do..." Celeste answered, returning Lydia's grin.
On the outside of Lydia's fire barrier, the king and his soldiers were powerless to do anything but wait and see what happens next. As soon as they saw the dome dissipating, they knew that their fates would be decided by what they saw. Everyone among them expected one of two outcomes: Either Lydia would be lying dead at Celeste's feet, or perhaps the other way around. Either way, none of them expected to see what they did. Both girls were standing very much alive, and Celeste's pure white robes were now black as night. Terrifying as the thought was, they all knew that this was the absolute worst case scenario. Lydia had brainwashed Celeste to fight for her.
Both girls turned toward the king with their hands on their hips and smirked.
"Sorry 'milord', but I'm done taking orders from a lying coward like you. I have a new master now, one who would never dream of throwing me away just because I grew too powerful for her." Celeste said, hugging Lydia.
"C-Celeste, I don't know what poison that witch has filled your mind with, but-"
The king was cut off as Celeste fired a beam of light from her hand that grazed his crown and vaporized a large portion of the wall behind him.
"Don't you dare speak of milady in such an insulting manner, worm! You have no right to address her as anything short of Goddess Lydia, especially after what you did to her!" Celeste yelled in rage, the venom in her voice terrifying everyone in the room.
Lydia simply smirked victoriously. She had this girl wrapped so tightly around her finger it was adorable.
"Goddess Lydia, I like the sound of that. Come, my dear, let's ascend to goddesshood and put this rotten old fool out of his misery together!"
"Yes, milady." Celeste agreed, fully understanding what Lydia had in mind.
Instantly both of them began to explode with growth. They quickly reached Lydia's previous height of 50 feet tall and just as quickly left it in the dust. within moments both of the girls towered over the king and his castle at an enormous 300 feet tall. The king gulped in fear as he looked up at the two towering titanesses that were getting ready to end his life. All of his soldiers were fleeing for their lives, desperate to escape from the colossal goddesses who wanted their king dead.
Just then...
