Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

Following a superbly successful fashion show, Rarity and her model, Anon, are invited to a night of celebration at a supremely exclusive establishment in the skyline of Manehattan. As it's usually open only to elites and celebrities, the two upstarts feel hopelessly out of depth, but they press on together; after all, no matter how much one's worries may weigh them down, they're bound to drift away in the Cosmos.

Tagged T for profanity, alcohol, and one passing allusion to intimacy.
