It was nighttime in Equestria, and while Luna (who is best princess) watched over the night and the dreams of her many subjects.

Her older sister, Celestia now slept.

To the realm of dreams she to ventured. Yet for a pony such as herself, dreams can be a thing of great sorrow

Celestia's subconscious first led her back to her phillyhood. Way before she was the great princess every pony knew her now as. To many of her subjects, they would think their rulers greatest heartache would be when she banished Luna to the moon. Yet while that was a large scar in her heart, many other wounds were also inflicted upon it.

In her dream, Celestia remembered playing with her Luna, and their friends. Twinkle Shine. A blue crystal earth pony with a yellow mane, and Rose Petal. A pink unicorn with a red mane

Her mind raced though all the good times the four of them had. Birthdays, playing in their old castle in the Everfree forest, sleepovers.

Yet as it did, Celestia and Luna soon noticed something. Twinkle and Rose aged. Aging ever so faster than the princesses. By the time they were the age of Apple Bloom now their friends were as old as Granny Smith. Which also meant that soon after...they passed

That was the first time Celestia and Luna felt true sorrow, the loss of pony they cared about.

Their father told them about their royal alicorn status. And how with that great title and power came deep prices as well. This was one of them. Which was also the reason Celestia nor her sister would ever have children of their own. What parent would wish to see their children have to suffer such heartache for over a millennium?

Celestia's dream now flung her into a cemetery. The tombstones of Twinkle and Rose in it. Yet soon more stones began to appear.

Every pony the the Princess of the Sun knew and had gotten attached to in some way or another. Guards, subjects, diplomats, Starswirl the Bearded, her own parents. Every time one came up she'd see a quick montage of images that showed how she knew them as friends. The list of names grew so vast, if Luna wrote them all on it, the paper it was written on would wrap around the moon. Suddenly though, Celestia came to a blank tombstone

"Who's this?" she wondered, her eyes now pink from all the sorrow and tears

Just then, a pink star appeared on the stone, and the name "Twilight Sparkle" was engraved upon it

"Sister!" Luna's voice cried as she entered her dream as well

"Sister I sensed you were feeling...Oh..."

Luna soon caught on to what Celestia's dream was about. Soon the Princess of the Night shed tears. Just cause she was on the moon for 1000 years, didn't means she to had friends and loved ones she had to see pass on

"Such is the price of our royal status sister," Luna said

"Indeed," Celestia said "It's our own curse, and may it never be passed on to another,"

The two sisters wept together in the dream, knowing at least all their friends, would be untied with their loved ones and other friends. In death

The end
