Silver raindrops, golden clouds

Candy Flower sat in her cottage, smiling upon her tiny new foal. The little filly was a light pink color, with her father's curly blue mane and strong wings. Candy Flower knew that her little girl would grow up to be a strong flyer. And in that moment, as the world welcomed her tiny child, moments after birth, she bestowed a name upon the little one, a name that this precious angel she now held would carry well. Storm Song. It suited the tiny pegasus well, her swirling blue mane mimicking the stormy curls of a rain cloud, bringing the sweet music of a spring shower to the world. However, unbeknownst to her, a very unfortunate occurrence for her was taking place in the palace.

Gold Soul walked into the throne room, feeling slightly anxious. His father almost never sent for him, especially in the throne room. He would usually just come find him. Whatever it was, it must have been serious. As he walked in, he gazed at the majestic beauty of the lunar throne room. He had always liked it, with the arching ceilings twenty or more feet above his head, embedded with diamonds in the shapes of the night's constellations. The large blue banners hung up beside the throne, hoof-stitched designs of the moon and some of the stars, were truly an impressive sight. He stood before his father's throne, waiting to hear what was so important. His father sat up straight as a poker, looking towards his son.

"Did you need something, Father?" Gold Soul asked, biting his lip just a little. His father inhaled sharply, which put Gold Soul even more on edge. He knew that meant his father was anxious too.

"Yes, my son. I'm afraid I need to ask you to do something very hard and painful, but it necessary for the good of all of Equestria." He said. Saturn knew that what he was about to ask his eldest son to do something horrible, but he didn't have much choice. He looked his son in the eyes, and inhaled again, knowing he was about to break the young stallion's heart.

"Some of our military's vital documents have been stolen. The thief also killed twenty of our personal royal guard. As a result, we cannot send our royal guard after this individual, for fear of losing too many lives. However, they have broken the law by stealing these documents, and also using forbidden dark magic to kill twenty strong stallions in the prime of their lives, and must be executed. However, you are the one stallion who can get to this pony without being killed. Gold Soul, you must find this pony, and deliver the killing blow yourself. You may do so however you see fit." Gold Soul puffed his chest up a little and saluted his father, as was traditional for his rank.

"I shall carry out your request to the best of my abilities. Who must I eliminate?" Gold Soul asked, feeling bad, but also furious over the deaths of his guard. What his father said next turned his whole world on its head.

"Your best friend, Candy Flower."
