Stella strutted down the aisle in all her glory, flanked by two guards. Shining Armor and his best soldier, Silver Sword. Celestia and Luna decided to make their reunion a little more formal than a "bathroom party." Well, really it had been Luna. Celestia was all for the bathroom party. She even suggested that they call Pinkie Pie, but Luna had vetoed it.
Stella was gorgeous, there was no doubt about that. She had white fur like her idol, a trait she regretted after their rivalry became public. Her mane flowed just like theirs, every alicorn from the alicorn worlds' did. She didn't have any necklaces or shoes, as a matter of fact, she looked rather bedraggled (though one would, if they had been imprisoned in the stars for a thousand moons, Luna figured.). Stella resembled Celestia so much that Luna thought, for a second, she was standing next to Stella. The main differences between them were their height (Stella was much shorter) and their mane colors. While Celestia sported a calming green, blue, and pink, Stella's mane boasted a blaring blue, purple, pink, yellow, and lavender.
"The princess, my lady," Silver Sword said, bowing at Celestia and Luna's feet. Shining armor echoed him. A glance at Stella's face told Luna just what she thought of that.
"Princess? My flank! What in the hay could have happened in a thousand moons that would make you so ridiculously commited to those- those- those mules!" Everybody gasped. Even Luna and Celestia were taken aback, and they were used to insults. Especially Luna.
Stella looked smug with herself for coming up with such an insult. Luna was thinking about banishing her to the stars again, and she was fairly certain her sister was, too, but before they got a chance, Cadance and the Mane 6 burst through the doors. Then they halted.
"Uuuuuh, who's that?" It was just like Rainbow to ask that. Luna sighed and called a meeting, so the twelve of them all made their way up to the Canterlot Library. After explaining Stella's story, (she set off to find her sisters after being left behind on their way to Equestria, but ran into Discord who imprisoned her in the stars for years thinking that the Equestrin sisters would go back for her, causing enough chaos for him to take over, but they didn't go back and Discord was turned into stone shortly after. This took nearly an hour to explain with Stella's interjection and theatrical pantomimes.) Luna and Celestia took Twilight aside and explained their history. Finally, a plan to start to be hatched.
"Why did you guys come to Canterlot in the first place?" Inquired Luna. Twilight opened her mouth to begin what Luna was sure to be a very lengthy explanation when Rainbow Dash interrupted her. "The map," Rainbow said. Twilight, her mouth still open, looked at Rainbow incredulously, then closed it and agreed. "It hadn't called all of us for a long time, so we knew it had to be urgent. Each pony with wings carried another. Rainbow took Applejack, Fluttershy took Rarity, and I-"
"Yes, yes, well that's all great. Could we please move on to sleeping arrangements? I am exhausted from all that imprisonment."
Luna sighed. It would be a long night.
