Luna meets Celestia's special somebody and gets the threesome of a lifetime.

AN// No angst. Just lots of fluff.

Celestia's morning has been difficult enough, between hearing Twilight's confession of love, and then breaking her heart as gently as possible. Mere moments later, her private chambers are rocked by the shockwaves of a time-traveling spell. This marks the arrival of Celestia's alleged lover from five thousand years in the future, Princess Twilight Sparkle—or as she insists on Celestia referring to her, Glitter-Flanks.

Armed with thousands of years of knowledge of which buttons to push and how to make her squirm, Glitter-Flanks has traveled back to this date for one singular purpose: to establish the closed time loop that sets the two of them up as a couple.

This story is a sequel to The Moon, The Flower, And The Door

"Anyone Can Be A Wizard..."

Morning Glory has succeeded in passing Princess Luna's test, and is now her personal protege... and soon to be her foster daughter. All seems to be sunshine, lollipops, and fluffy puppies forever... until Luna makes a discovery regarding the young filly's parentage, one that could wound the young filly's heart terribly. Keeping this information a secret seems wisest, especially given the connection the young filly has with Celestia's new student, but it soon becomes clear that this is just the tip of the iceberg, as the filly begins exhibiting strange and seemingly inexplicable talents. The young filly seems intent upon becoming a wizard, in spite of being an earth pony. Is such a thing possible, and is Equestria ready for it? And if so, what kind of a wizard would she be?

One thing soon becomes clear: No matter what the outcome turns out to be, something big is about to happen in Equestria, and when it's all over, nothing may ever be the same....

Having spent nearly a year in Celestia's court and by her side, the first and only human in Equestria is in rapidly deteriorating health. And despite all of her power, Celestia finds herself unable to help him.

(Written for the Most Dangerous Game contest, and in far less time than I would have liked. AU tag because for purposes of this story I'm ignoring the mirror world where Equestria Girls took place—this Equestria has no knowledge of humans in any way.)

Royal Guard Silver Birch knows Princess Luna's history, and her... extreme reactions to being neglected in the past. When it seems Luna has been snubbed yet again, he and his partner Winter Garden take action to shield their Princess from this slight, and spare Equestria her terrible wrath.

(Inspired by a really dumb blog I did.)

After a magical accident, Celestia and Luna must try to restore harmony. Celestia's duplicate, however, is having none of it.

A young earth pony named Morning Glory is going to find out.
