Celestia inhaled the cold night air as she sat on her balcony in Chanterlot Castle. She looked up at her sister's moon, then down below as the first day of preparations for Twilight's coronation came to a close and everyone started to head home so that they could resume their work from tomorrow when the actual ceremony would take place.

She quietly sipped her tea and allowed her memories to wash over her. Despite such a joyous occasion happening, Celestia and Luna were sad. They hid it well. But they knew it had to come at some point. Better late than never. She heard hoofs walking across her marble balcony. She didn't even move as her sister, Luna sat down next to her in silence.

They stayed like that for a while. Simply enjoying each other's company as they knew they had limited time left to do so.

"Do you think...There is a heaven for Alicorns?" Luna finally asked. Celestia let out a soft chuckle and placed her empty teacup down.

"We were originally unicorns. We will probably just go there...If there is a heaven of course." Celestia replied. Luna sadly looked down to the streets and houses below. Then up to her beautiful moon that shined down on the two Alicorn sisters.

"I am assuming you haven't told Twilight yet." Luna commented. Celestia nodded.

"No. I am allowing Cadence to tell her a few weeks from now. She doesn't need her special day ruined because of her loyalty to us."

"We should tell her." Luna flatly replied. Celestia sighed in irritation. "It will hurt less coming from us."

"Why are you so worried about her knowing before we leave, Luna?" Celestia asked with a raised eyebrow. "Please...We don't want to make a scene."

"But...You are her mentor. She had a right to know that...We are going to die tomorrow."

"My decision is final." Celestia barked. "It would be too late anyway."

Luna nodded and stood from her spot.

"I have to go patrol the dreams of our subjects one last time. Since we will be gone by this time tomorrow, I have to help as many as I can." Luna explained. She trotted out of Celestia's sight and back into the castle where it was warm.

Celestia shivered at the chill of the air and her eyes drifted to the town with a crystal castle in the distance. A lone tear drifted down Celestia's cheek as she considered her fate. The fate of her sister. And the fate of her pupil. She levitated her crown off her head and took a moment to look at the gold crown with a purple crystal in the middle.

Luna had already transferred most of her magic into her own crown. It was Celestia's turn.

Celestia poured her yellow magic into her crown. It was over in a matter of moments. Celestia sagged at a feeling over being suddenly very weak and dizzy. She shook her head and pleaded with herself to pull it together before using her hoofs to place it back on her head.

She felt that her spirit was dying. It was. Celestia used half of her limited magic supply to keep herself alive for just a little while longer. When The crown was to be turned into Twilight's she would get their magic. She would be able to control the sun and moon.

Celestia and Luna's duties would be finally finished and their destinies would fade. The years and centuries that they lived would catch up to their unicorn bodies and they would simply turn to dust. They were never meant to become Alicorns and they both knew it.

Starswirl predicted it would happen.

Celestia looked over to her room, that the maids and servants had started to pack away. Not that she would need any of it. She was going to miss living. She was going to miss them all.

Suddenly, there was a flash of light. She didn't jump up in alarm as she had become used to Discord dropping in at random moments. He appeared as the light died away and gave her a long angry expression.

"How could you not tell me, Tia?" He growled. She turned away from him and looked down to the ground in shame.

"You can't do anything to stop this. Dizzy." Celestia replied, using the nickname she gave him when they first met. "It's over for me and Luna. I couldn't tell you because you would try to stop us. You would tell Twilight to convince her to not take the throne."

"Is that really such a bad thing?" He replied. Cautiously hovering next to her. Celestia's sadness overtook her and tears started to silently fall down her face.

"Yes." Celestia said. Offering no explanation. "Please. Don't tell the others."

"Don't worry, Tia." Discord replied. For the first time, he was actually taking a situation very seriously and following her request. "I won't."

Celestia took in a sharp inhale as she tried to stop herself from sobbing in front of her friend.

"Discord..." She said quietly. "I am really scared. I don't want to die."

Discord pulled her into a hug, allowing her to have the first real cry she had in years.

(Three hours after Twilight's coronation.)

A unicorn version of Celestia stood in a field near the end of Equestria. The sun had begun to set, thanks to Twilight's new power. The mane 6 had seen them off from the train station in Canterlot. There were heartfelt goodbyes and promises to see each other again.

But Cadence, Celestia, and Luna all knew they were empty promises. At least on the sisters' behalf. She used what magic she had left to keep her alicorn appearance until she got off the train and entered the field in the middle of nowhere. A smaller unicorn mare, Luna trotted up next to her and looked over to her sister's cutiemark.

"Your cutiemark is fading, sister." She commented. Celestia looked over to her cutiemark and saw that it was indeed fading. She looked over to Luna's and saw that her sister's cutiemark was in the same state.

"It shouldn't be long now." Celestia replied. They both settled down on the soft grass and flowers and watched the sun disappear over the horizon. Celestia gasped as petals left her body. Her body was turning into petals.

"I hope heaven is nice." Luna said as she watched her hoof slowly disappear and turn into petals, flying away in the soft breeze. She looked back at Celestia with fearful eyes. "I really hope it exists."

"Me too, Luna. Me too."

They closed their eyes one final time. Allowing the wind to take them away to a better place.

---The End---

Author's Note

A revised version will be coming soon. It will include more of Celestia and Luna's history, it is going to explain how Cadence found out about their condition and Twilight's reaction afterwards.
