Also known as, the Twilight.
I feel like this story doesn't need much of a description. After DJ Valkyri-3 I wanted to write more cutesy romance and see if I couldn't squirm my way back into ponified. Saw the picture and, well, this happened.
Also, I never really see Twilestia from Celestia's point of view. It's always form Twilight's or an omniscient view so I thought I'd try it out. Turns out it's really fun to write!
Enjoy!

Added the sex tag for chapter 2 specifically, but unless insinuations without real descriptions and raunchiness with a dose of lewd iconography rubs you the wrong way then it's perfectly safe. It's still nowhere near needing the mature tag.

When Spike dies an unexpected death, Rarity decides to take matters into her own hooves. She pulls out her sewing needle and her best thread, and prepares to 'fix' him.

Now with a great reading by Brad the Browncoat Brony!

SEQUEL IS OUT

Rarity's quest for love led her from Tartarus to Canterlot. Now, wielding powers beyond comprehension, she rules over Equestria.

Now, if only she could understand how Fluttershy's little cult had gained thousands of members virtually overnight, or why the cult's second-in-command, Twilight Sparkle, always seems to be one step ahead of her...

Some RariTwi written for the December Crackship Contest. My prompt was "Heartless Dictator Rarity + Cult Meeting + Star Student Twilight" (and since she appears on the "Cult Meeting" card, I decided to also use "Cult Leader Fluttershy")

Cover art done by the amazing Earthsong9405 (Tumblr, DeviantArt). Given how her AUs (via Monochromatic's "The Sphinx's Riddle" and "The Princess's Choice") have warmed me up to RariTwi, I found it rather fitting to commission her to do the coverart for this RariTwi AU.

Sex tag might be overly cautious, but I prefer that over being banhammered. Nothing explicit, no smut here, it's just being mentioned/discussed, and Rarity has some short fantasies that she is quick to shove aside.

For Doctor Twilight Sparkle, life at Canterlot National Hospital was pretty good. She'd struck up a bond with the director and even had enough time to publish a paper or two. There's only one thing she needs to advance even further: better bedside manner.
For these reasons, Doctor Celestia carts her off to a tiny Ponyville practice. Now, Twilight must find a way to both cure and tolerate the village idiots--and try to convince a certain high-strung healer that she's not after her job.
