Luna

"Worry not, Twilight Sparkle. I shalt return to help the ponies of this fair land, and bring back your princess."

Luna looked across the vast expanse of terrain between Canterlot and the borders, onward onto the northlands, where the Terr Mountains resided, and the key bringing back Celestia in a temple perched upon a promontory.

She watched closely as the sun set, and night began. She spread her wings as soon as the sun's top drowned under the horizon and took flight, beginning her journey. She flew slowly, so as to spare her energy for the coming hours, where she would not get any sleep.

Her head could barely comprehend half of the mess that had just happened a few hours ago. The entire event still unfolded moment by moment in her head, a flickering replay of Celestia's limp body collapsing onto the white tile, blood coming from the point where her wings met her body, and her horn, which had cracked open.

Luna had been awoken by a royal guard, who immediately told her about Celestia's sudden raving madness. She had walked into the main hall to sudenly see her collapse, for her body to go slack and fall, for her muscles to stop functioning as normal.

Luna took a deep breath of the air, which held a fragrance of conifer trees and a cold bitter wind, and set her mind onto flying once more.
