Celestia raised her head from her pillow, it was about time for Luna to lower the moon. She stood and stretched out her back and wings with a loud before opening her eyes. Her eyes widened immediately as she was standing in pure darkness, almost as if a shadow had swallowed her whole in her sleep. "Luna?!" She swings her head around and frantically looked for another pony. "Is anypony there?!"
"Dearest sister did you forget how to use your inside voice?" Celestia swung around once more, the voice echoing from the darkness.
"Who's there?!" She yelled into the dark before looking around, the clicking of an annoyed tongue answering her.
"Still so loud, where are you manners when greeting family?" She narrowed her eyes and stood tall, her legs positioning into a fleeting stance as she bunched her muscles to run.
"Midnight." She looked behind her as a dark grey Alicorn mare walked out of the mass of shadow into view, her body was as elegant looking as Celestia's herself, Her mane was a chaotic mess of a thick black mass of shadow that swirled her head in a distorted wave that would occasionally connect and bunch with the mass that stood as the mare's tail as she walked toward Celestia slowly.
"Celestia, dearest Tia." She smirked, her single eye that shone burned a bright red as she started to back her sister down. "It is so good to see you with my own eyes."
"How are you here?! Luna and I ended your life eons ago!" The very light pink Alicorn took a step back for the grey mare's every step forward.
"Honestly, how long did you tell yourself that lie?" The mare lowered her head, her horn glowing an onyx black as Celestia continued to back away from her. "I never left you and I both know this." Celestia backed into a grey solid rock wall, causing her head to swing around and her eyes widened at the wall ."It does hurt that you thought of me as dead, though a sword through the heart does sting more than you would think." Celestia looked at the mare, her eyes wide and her pupils nothing but pinpricks in her eyes as her heart rate increases out of fear. "Anyway, lovely isn't it?" The mare looks around her, beckoning Celestia to wearily look at the blackness around her, the seeming forever stretching wall behind her blocking her from fleeing. "You think that something of my design would have more of a, homey feel." Celestia creased her brow in confusion as the mare meets her gaze. "Yes you imbecile we are inside my mind inside your precious gems. Your Elements of Harmony."
"But how...how is this possible…?" The mare rolled her eyes and sneered at the pinkish white alicorn before her.
"HOW NAIVE ARE YOU CELESTIA?! I DIDN'T DIE WHEN YOU STABBED ME! I SEALED MYSELF SAFE WITHIN THESE GEMS TO SAVE MYSELF!" She snorted in frustration as Celestia mumbled with trembling lips.
"No, thats impossible. Not even for your level of magic." She jumped as the mare before her began to cackle wildly.
"Are you that naive? My magic is unique and you know it sister. Discord's chaos magic along with black magic? Honestly how stupid are you?" The mare turned her back to Celestia. "I am coming for you dearest sister, I have absorbed enough magic and I will return. Be prepared for war from my time sister."
Celestia jerked her head up from her pillow with a loud panicked gasp, her body trembling as the words of the grey mare echoed in her head. Her fur stood on end as she looked shakily at the moon from her window, her pupils pinpricks as Luna knocked open the door.
"Sister! What's wrong?!" Luna rushed to Celestias side in attempt to calm the startled mare.
"M..midnight is returning.." Celestia murmured as Luna nuzzled her, the words causing the dark blue pony to freeze. "War is being brought to Equestria from within it's own walls sister..Call forth the Elements. I must speak with them immediately."
