It was eight o'clock at night when Princess Celestia sat in her room on a pillow, going through her mail and she came across a letter unlike the rest. This one was not made of paper, rather, it was made of spider silk. Excited, Celestia opened it with her magic. It read:
Dear Princesses Celestia and Luna,
I'm sending this letter as a heads up, since it's kind of rude to drop by unannounced. I'm on my way and will probably reach Canterlot in three hours. If you want to make preparations, do so. Sorry about the timing, but you know me. I come bringing great news, good news, bad news, and horrible news.
See you when I get there,
StarFrost
Celestia grabbed the letter and bolted to Luna's room.
"Luna, Luna," Celestia called, barging in on a shocked Luna. Celestia usually had better manners. "Read this," Celestia said, handing the letter to Luna without an explanation. Luna read and, with each word, her expression grew more and more excited.
"StarFrost is coming," Luna said, practically bouncing off the walls "That explains why the stars are hiding."
"I'm going to go write letters to Cadence and Twilight, telling them to come as quickly as possible," Celestia said. "I hope these bad news isn't too horrible, it'll be nice to catch up." Celestia then headed up to her room to send theses letters.
Pretty soon, Cadence, Shining Armour, Flurry Heart, Twilight and the other Elements of Harmony were standing in the courtyard of Canterlot Castle with Luna and Celestia.
"If someone important is coming, shouldn't we be waiting by the train station," Twilight asked, feeling a little impatient since the letter woke her up.
Celestia stopped watching the sky for a moment to look at her and say, "They're not coming by train, Twilight."
Luna called at that exact moment, "There they are," and pointed at the sky. Everyone looked up and saw what could be described as a flock of moths. The first one landed and everyone realized that they weren't moths, but ponies with moth-like wings.
Luna and Celestia ran over to the first moth pony.
"Hugs, support, well wishes, best friends, no matter what," the three of them said while hugging. Fluttershy ran over and started looking at the wings, with Twilight not far behind.
"What are you,"Twilight asked the first pony that landed.
"We are a race that lives deep in the Everfree Forest called Flutter Bugs," StarFrost said.
"Oh, big sister, I missed you," Luna said, whipping her eye.
"I missed you too, little sister," Celestia said. They had both said this to StarFrost. Looks of shock and surprise were exchanged in the crowd.
"Aren't you going to introduce me, Celestia," StarFrost asked.
"Oh, right, of course." She then turned to the nine gathered ponies. "Ladies and Shining Armor, this in my sister, Captain StarFrost, of the Flutter Bugs."
"Actually, it's General now," StarFrost said, loud enough for everyone to hear.
"Really? That's great. You have to come inside and tell us all about it," Luna said.
"Don't forget why I'm here, Luna. We'll go in to talk, but about that," StarFrost said, and turned to look at her fleet. "You eight go to the pegasus barracks. I'm sure one of the Royal Guard Pegasi will show you the way. Only take up two beds," she ordered.
"Yes, ma'am!" They saluted her and flew off.
"Shall we," StarFrost said, turning back to Celestia. They all walked into the Canterlot Castle.
While they were walking, Twilight analyzed StarFrost. She was a snow blue pony with stars sparkling through her mane and tail, which were white with dark blue highlights. She was the only Flutter Bug with a unicorn horn that Twilight's seen so far.
"Where are the stars," AppleJack asked, feeling a little jumpy.
"StarFrost, would you please," Celestia asked.
"Why not, just remember who's in charge," StarFrost replied with a total middle child sarcasm. Her horn started glowing and she flew into the sky dramatically and the stars flew off her tail and mane and into the sky, forming constellations. Twilight's, AppleJack's, Rainbow's, Pinkie's, Rarity's, and Fluttershy's mouths dropped and were still open in shock when StarFrost landed.
