Luna vanished and Princess Celestia fell forward onto the grass. "Wa...What?" She said in disbelief. "No, no, no, no." Tears flowed down her white cheeks. Her cry was loud and echoed through out the field. "What have I done? I...I should have died, but...but I was so selfish." She said and then cried for a few moments more and then spoke as she wept, "I killed everything just to save myself." She paused again to let out her tears and cries and then started again. "I'm sorry Luna...I...I should have been there for you. It's my fault. I'm sorry." Her heart ached and her body quivered. "I'm sorry."
The sun hung in the sky. In fact it hasn't set in the past day or two. In the midst of Celestia's crying she fell into a deep sleep in the grass.
~~~~~~~~~~~~~~~
Celestia found herself no longer in the field. It felt like she was standing inside a cloud, all around her was swirling white clouds. She found herself amazed that she wasn't scared and that instead of fear she felt at peace. Where was she? It was unlike anyplace she's ever been. The clouds felt soft and incredibly comfortable under her hooves and the air smelt fresher than any air she's breathed.
In the clouds there was a familiar shadowed figure. Another pony maybe? She galloped as fast as she could towards the figure but the more she ran the farther away it seemed to get. "No, wait. Please." Celestia called out and then after those words the figure vanished. She stopped and lowered her head. One tear fell from her eyes and landed on the cloud. This was strange because tears would just go right through the cloud.
"Big Sister?" A familiar voice said behind her. She turned around and saw standing about six feet from her was Luna.
"Luna?" The sun princess said. "Is...is that really you?"
"Yes, Big Sister. It is me." Luna said.
Celestia leaped and tried to wrap her forelegs around her but she just went through her. Luna faded into a mist and then reformed just in front of Celestia who was now on the ground with a look of confusion on her face. "Are you real?" Celestia asked.
"Yes, I'm real."
"You're dead aren't you?"
"Yes, but my spirit lives." There was a long pause while Celestia thought to herself. Luna spoke again. "I've been watching you Big Sister, I've been listening to your thoughts. You blame yourself for the destruction of Equestria, but I appear before you to tell you that you shouldn't blame yourself."
"But Luna, I killed them all. It was me. It was my fault. I-" Luna cut her off by raising her right hoof.
"You did what you had to do. I would have done the same." Hearing this made the guilt lessen but it was still there deep in her heart. "Equestria was already doomed, you spared them all from a fate worst than death."
"But it's my fault you're dead. I should have gone with you to Cloudsdale, maybe you would still be alive."
"You had to stay and try to defend Canterlot. If you came with me you too would be dead. Life must go on. I don't have much time now." Luna said feeling a little guilty.
"Please don't go." Celestia jumped up from the soft ground. "I don't want to be alone."
"You are not alone. You were never alone." At that eight ponies formed on both sides of Luna. Light filled Celestia's spirit as she looked at the closest ponies she's ever known: Pinkie Pie, Applejack, Rainbow Dash, Rarity, Fluttershy, Cadance, and even Shining Armor. But out of all the newly arrived spirits the one she was most happy to see was Twilight Sparkle. "Twi...Twilight?"
"Hello Princess." Twilight said and all nine of the spirits knelled before Celestia. They rose seconds later and then Twilight spoke. "Princess, you have taught me so much. But the one thing you helped me learn is greater than all the other knowledge in the world. You taught me how to be a friend. You've always been there for me when I was a filly and I am happy to call you my best friend. We'll never leave you and even though you can't see us just remember that we are still there by your side. We love you Princess Celestia."
"I love you too." Princess Celestia said as a tear fell from her eye. The nine ponies went up into a colorful mist and the colored mist shot into Princess Celestia's chest. At that she woke up back in the field. Her body felt very warm from the sun's heat beating down on her for such a long time. She felt different. She felt happy. The first time in over a year. Her heart beamed with joy and she took flight into the sky. Her horn glowed and the sun went down and the moon rose in its place.
