When I commissioned this, what I had in mind was the future-verse that I haven't gotten around to writing a full story in yet. A few centuries from the present, the two

alicorns are Twilight (centuries old but not quite up to her mentor's level; sometimes she has to scramble to hold things together.) and a fusion of Shiny and Cady (after centuries in this form, by now s/he is thought of as one pony by even him/herself and Twilight.) But, even if you're running the world and seen as gods by its inhabitants, it doesn't mean you can't be playful now and again. Twilight is the one who sometimes forgets that, so when she visits the crystal empire, the one pony who doesn't need her to be a larger-than-life figure reminds her to lighten up now and then.





(Celestia and Luna aren't dead or anything, but what did become of them is a bit of a spoiler for if I ever do write this.)
