Celestia lay in bed, wondering how the rest of her life would be without a sister to support her side, or even bring back the night. She was sure that Luna was watching over Equestria with her same regal care.
The white alicorn sighed, shutting her eyes for a moment. She hadn't meant to fall asleep-after all, she had her royal duty to conduct-but she did anyway, waking up to a world of white.
"Where am I?" she whispered, trying to move her flowing mane in order to gain more vision.
"Tia?" a voice called throughout the thin air.
The voice and tone sounded vastly familiar-she whipped around to see Luna, her sister. She looked young again, without her starry, flowing mane. It was the same style she had after she was unlocked from the horrifying powers of Nightmare Moon, when Twilight and her fellow friends helped.
"Oh, young sister!" she cried happily, trotting towards her. But instead of a warm embrace, the Night ruler backed away, looking downwards.
"Sister?" Celestia repeated, slowing her pace to a halt. "Is something wrong?"
"Of course there is," Luna whispered hoarsely, sounding like there was a lump stuck in her throat. 
"But, besides your death, I mean," the Princess of the Sun sputtered, bewildered by the sudden emotional discharge.
"I, I...I know Twilight told you why I fell off that balcony overhang," Luna sighed, settling on her haunches and making straight eye contact with her elder sister. "But I didn't tell her all my exact reasons."
"Oh?" The white alicorn sat in front of her, intrigued and curious to hear her sisters thoughts about her own role in royal hierarchy. 
"I had that same jealous feeling that I got those thousand years ago," she confessed, shaking her head. "When ponies basked happily in your light, and slept through my night..."
"But, sister, that was so long before. Why are you letting the past get ahold of you?"
"Because.." Luna choked on the lump that was stuck in her throat before speaking up again. "Because I was thankful that I had a life of love and warmth. I just wanted one more touch to make my life perfect."
She began to sob once more. "I'm so selfish and greedy. I can't believe I thought that, and that's why I wanted to be taken off of Equestria."
"Luna." Celestia stood up, trying to shake the feeling that her sister wanted a better life. She felt guilty that she didn't provide her with enough encouragement that her night was beautiful, and everypony was glad that there was a time of a full day where they could rest and have cheerful dreams.
"I understand that you felt like you needed a more perfectly balanced life," she began carefully, trying to choose the right words. "But you know you can always come to me. I'm your older sister-I think I feel responsible for your death, having not providing the encouraging words for you. Please, forgive me."
"Tia, it is not your fault at all," Luna protested, frustrated. "It's mine. I'm such a filthy, greedy selfish mare that's completely insecure and can't even control her own emotions. Therefore it is my fault, and never will be yours no matter how many times you say!"
She stamped her hoof and the white atmosphere shook for a moment, bouncing up and down like ball. The solid feel of the ground cracked, opening into a black gorge in between the sisters. The plates of the dreamland shifted, and the two alicorns were separated.
"Luna..." Feelings of hurt swept up Celestia. 
Luna, on the other hoof, looked fierce with a glint of red mist floating in her blue eyes. "You'll accept my decision. It was my fault that I died. Who's the one who came up with the idea? Me! Who's the one who committed suicide? ME!"
"I understand," the white Equestrian ruler interrupted before her younger sibling could come up with another exclamation. "You don't have to get so furious and angry about it. Dear me.."
The mist in Luna's eyes faded as she realized she had gone too far. She backed away again, as if she had just noticed the deep pit she created. "It is time for you to go," she whispered, letting her slender horn light up. The dreamland died away into nothingness and Celestia woke up, gasping for breath. She could hear a crowd outside.
"Twilight Sparkle! What else happened?"
Although moments of tension had passed by, the Princess of the Sun couldn't help but suppress a smile of amusement. The Canterlot ponies were still clearly wondering about Luna's unfortunate fate.
She got out of her bed, quickly combing her mane. She opened the doors to the overhang where the Princess of the Night had cried before. The ponies all stopped attacking Twilight and looked up at Equestrian's ruler.
The same questions were thrown back at her. "Why did she die? Your faithful student isn't telling us why!"
She could understand her pupil's refusal. The purple unicorn was obviously trying her best to stay loyal to a dead Luna, and not give out any secrets even if they weren't the actual ones.
"Please, enough of this havoc," she ordered, quieting the crowd. "Go back to your work, go back to your homes. You'll all know soon enough, but now is not the time to share the last moments of Princess Luna."
But even though Celestia said this, she felt herself that she wanted to share her knowledge with others. Her sibling had never mentioned whether she could tell, anyway.
Twilight gasped with relief. "Thank Celestia! Literally," she added with a smile, trying to add a cheerful tone.
"Your quite welcome, Twilight. But now, you must resume to your studies. Do tell..Why were you here in the first place?"
The unicorn shut her muzzle. "Er, I'm your student, aren't I? I'm just trying to get here early, ya know..."
Celestia's fellow pupil was clearly not being direct with her mentor, but now was not the time to dig into any suspicions. "Alright, Miss Sparkle." She dismissed her with a single stretch of her right wing.
As her student left, the Sun brightened and blinded her vision. A series of mixed flashbacks all played in one second.
The flashbacks were all Luna-based. Celestia couldn't tell if it was a sign, but it ended just as quickly as it came. And for some reason, it brought a smile to her face.
