Luna walked down the halls, a spring in her step from the recent turn of events. Her sister had been more jovial in recent days, her smile had returned and it shined brighter than before. She was almost curious as to what had broken the ten year streak of mourning Twilight’s death.
As she continued to her bedroom, she overheard some maids speaking.
“Have you see the cloaked pony wandering the halls?”
“Yes, just being near her creeps me out. How does Celestia handle being near her?”
“I saw her eyes once, a deep purple that felt like they were… trying to steal my soul.” The maids shuddered when that thought came.
Luna stayed silent, she had seen the cloaked mare once and she thought it was a trick of the mind. But this confirms it, the purple eyes and Celestia happy again were too coincidental, she had to approach her sister about this matter before it was too late.
She stormed to Celestia’s quarters and bucked the door open. “Sister, Do you have any idea what you’ve done!”
Before her was Celestia blowing raspberries into an animated skeleton, her body glowing an eerie purple, blue fire emulated a mane, and just as the maids said, Luna could feel the purple eyes piercing her soul, but there was fear in those same eyes right this moment. All three stared at each other awkwardly until Celestia broke the silence. “Sister, how are you?”
Twilight nervously waved a boney hoof to the Lunar Princess. “Hi Luna, I’m back.”
“You performed black magic! Do you have idea what that will do to you?” Luna shouted angrily.
Celestia stood up, staring down her sibling. “It means that one day I will become my own version of Nightmare Moon, forcing you to banish me before I hurt anypony.”
“What?” Twilight asked. She stood up and placed a hoof against Celestia’s foreleg. “You risked it for me? You didn’t-”
“Twilight,” Celestia interrupted, surprising the skeletal mare. “For ten years, I cried. For ten years… I felt hollow without you.”
Twilight gave her lover a concerned look. “But… what about Equestria? Surely they need you more than me.”
“This isn’t about what Equestria wants, it’s about what I want,” Celestia replied, her voice cracking a bit. “For eons I have led my little ponies, but I never got any time for me to be selfish, to allow myself some time to rest and relax, until you came into my life. When you died, I felt betrayed by life itself. Until I remembered a certain spell.”
“Thus, you made resurrecting Twilight as a Skeletal abomination as your due for all you've done for Equestria,” Luna stated, getting slapped hard enough to fly into a nearby wall.
“Twilight is not an abomination! She saved you, in case you’ve forgotten, dear sister,” Celestia snarled, stomping to Luna’s body.
Twilight quickly put herself in between the two princesses. “Stop, this isn’t you. Please,” Twilight whimpered, hoping that the white alicorn would listen to her.
Celestia’s ire drained, slumping down. “You’re right, I’m sorry Luna. Just… don’t speak of my Twilight that way.”
Luna groaned as Twilight helped her up, forcing her to put her weight onto the icy bones that held her. “V-Very well, I apologize for calling you an abomination, Twilight.”
“Don’t worry about it, Luna,” Twilight chirped happily, content that the fight had stop. “Truth be told, I’d call me an abomination, just look at me. Also, it feels like it’s hard to snuggle me when I’m so cold and boney.”
“Twilight.” The skeletal pony flinched when she heard her lover’s stern voice. “Not even you are allowed to call yourself an abomination.” She felt herself scooped up into a tight hug, snuggled from behind by the solar monarch. “And your company is all I need.”
Luna’s features softened as she watched the scene. She then noticed Twilight giving her a worried look. “I’ll do my best to make sure she doesn’t become a Nightmare, Luna. I pinkie promise.” Twilight smiled. She then performed the oath with her hooves before getting one of them stuck in her eye socket. “Uh oh.”
