Era: 600 AC, New Equestrian Age, 60 Years before Crystal Uprising
Dear King Sombra,
I write to you right now if you in great urgency. Our subjects’ have been tormented by phantoms that my sister can’t diminish. They appear to be pony, but are merely shadows in form. They are anomalous in behavior, because unlike regular nightmare’s, ponies have been experiencing long term damage to their behavior, causing some to go insane, or even worse, criminal. In fact, we have reprehended a pony today for smashing a porcelain flower pot, and using it as a weapon against a guard. The worst part was that her eyes were discolored, almost like the regular color was drained, and was replaced with the eye of a cat. Even with my knowledge, I do not know of how to handle this situation without calling the Element Bearers to risk their lives, just as they had done in the Great Abyss Incident. As I’m aware that you are currently busy in preparations for the Summer Sun Celebration, I would like to know if your people have been suffering the same nightmares.
Your Queen and Faithful Friend,

Celestia
“It’s a scary thing, isn’t it brother?” Turquoise said as he bit through another piece of a dandelion sandwich. Him and his little brother were eating in the dining room, well he was anyway. He looked up to see his little brother fiddling with his little Ukulele, letting out a small chord as it rang through the quiet house. “Brother?” His little brother looked up from his strumming. “Yeah, I guess…” Turquoise picked up the newspaper he was currently holding and hit his little brother in the head. “Ow!” He said as he rubbed his little hooves through his now slightly throbbing head. Turquoise smiled, and continued reading the newspaper.
Even though he was smiling on the outside, he was extremely worried on the inside. This news of nightmares all over Equestria has been stressing everyone out. In fact, his imports on valuable stones are running late because one of the workers called in on a sick day. It was putting a terrible stress on the profits his Jewelry store was making.
Besides that, the people in Hollow Shades haven’t been experiencing any nightmares of the sort. That’s all good with him, he didn’t need any more chaos than he did right now. As he thought that, he waved his hood over his head to clear of any bad luck thinking of the chaos bringer could possibly bring. He looked over at his brother again. “Oh well.” He thought to himself. “Hey Meadow,” His little brother looked at him again. “Put down your little toy guitar and play with the other foals.”
“Okay big brother.” Meadow got off the dining room chair and sat the guitar up against it. Pushed open the door and trotted outside, where he could already hear the foals squeals and laughter. He shook his head and sighed as he put down the paper. “It looks like I better get going as well; it looks like I’ll have to head outside Hollow Hold to find any chance of getting jewels.” And with that, he finished his sandwich, and headed out.
