The princess was silent yet Twilight was somehow louder — in her mind, it's uncontrollable. Her thoughts soar on, the painful ones and the sentimental ones. When Twilight lost her friends, one by one, friendship's light had began to fade away... at least to her. She still keeps remembrance of their last moments.
Every one of them were high at age while Twilight herself stayed looking young. And to see them parish right before her eyes simply broke her. She will always keep their final words in heart.
The five ponies gather around their friend one last time. Applejack begins to speak.
"Gals, ya' know I love you all... ver' much." Applejack coughs roughly. "But I guess it's my time to go. Be at rest. Like Granny Smith said on 'er last moments, 'Not all apples are fresh, most of 'em will rot over years. And ain't that just like a pony's life, new apples will grow and old apples will be thrown out. Some apples 'er rotten to the apple core while others are worth cherishing'. I ain't one for goodbyes but lemme just say... ya'll are the apples of my eye and i will miss ya'll as much as ya'll miss me. It's been great, Pinkie, Dash, Rarity, Fluttershy, and Twilight... I hope you'll be happy the rest of yer life Sugarcubes."
Suddenly Applekack closes her eyes. And she stops breathing.
Everypony's eyes water, with smiles on their faces.
...
"Twilight?" The princess spoke.
Twilight gawked at Celestia, who had her eyes on her. Twilight took a few seconds before forming a response.
"I'm sorry," Twilight says without thinking.
"What for, Twilight?"
I don't know... why did I say sorry?
"For bringing up my friends, I guess." Twilight bows her head.
Celestia almost doesn't respond.
"Twilight, there is nothing to be sorry for. You miss your friends, that is understandable and certainly nothing to apologize for." Celestia continues on.
Twilight says nothing, her mind races on of her loved ones whom have passed on. As she accompanies Celestia through the Castle halls, she nearly doesn't recognize her are. She has only been in one part of the Castle after all — her sanctuary, as she would call it. Merely since she surrounds herself in books, in which she has read every one of them at least twice. But it isn't enough to cope with her longing sorrow.
It's as if she can recognize Princess Luna's feelings when she was once banished to the moon, the thought of being trapped. That was different, however, Luna was not herself — she was cursed with hatred and abandonment by Equestria. Or so she thought. Twilight feels isolated without the ones she cares for, as if they made her life meaningful. Most of this reason goes to her friends. They taught her a different kind of magic.
Friendship.
It seems my time has come, Twilight. I can feel the pressure of death coming ever so closely. It's beautiful."
"Rarity...please don't go."
Rarity puts her hoof onto Twilight's muzzle, hushing her.
"It's okay, dear. I'm glad you are here and only you. I just felt the need to speak with you, for my finals moments. Since you are very special to me." Rarity exhales slowly, "Twilight, you are truly the greatest pony I know. I know you will become something greater, something more stronger. Nothing can stop you, Twilight Sparkle. You are unique. Don't ever change who you are."
Twilight lays her hoof on Rarity's fading heart. It feels strong.
"It's fine, Twilight. I'm fine. And I know you will exceed such condition." She smiles softly, with tears in her eyes.
"Yeah... yeah, I'll be fine," Twilight says, with long streaks of water gliding down her cheeks.
"Perfect." She whispers.
...
"Do you remember these moments, Twilight?" Celestia asks.
Twilight looks up — the tall glass windows with mosaic art stand, representing the victories throughout Equestria. She looks around, seeing all the good she has done. She remembers every moment in which she saved Equestria with the Elements of Harmony... with her friends.
Every window were four hundred years old, the ones with her friends however. Recently Twilight had fought and protected from ultimate dangers. And those moments are there as well. On one, there was a mosaic of Twilight defeating twin Ursa Majors. On another was every princess fighting off the army of griffons, along with many royal guards. She remembers how many casualties there were, how long the war lasted.
The glass mostly showed the power of the Elements of Harmony and how they are best when formed together. Those times with her friends, the ones where hope was gone but restored. There, on another, Twilight saved her friends when Discord once again brought chaos, he was stronger at that time. He made her friends turn on her. But she had done what she had done before. And Discord is once again stone, locked away where only the four princess' can unlock.
They have done so much for Equestria, they have saved countless lives. Twilight did not expect the death of her friends in return. It's for the better, she would think. But that was before, when memories did not demand her attention. Now she can't help it.
And she continues to struggle with immortality.
