Nopony ever really knew much about the alicorns that came before Celestia and Luna. Without any prior knowledge, they just assumed that the sisters were immortal due to their age. Thing is, they weren't.
After their four thousand years were up, Celestia and Luna were taken from their mortal bodies to join their fellow passed in the Manaveil. This left behind two more, of course- such is the way of things.
Princess Mi Amore Cadenza, niece of the sun goddess, who now raises and sets the sun in honor of her dear aunt, Celestia.
And Princess Twilight Sparkle, who raises and sets the moon and stars in memory of her loving wife, Luna.
Now, one hundred years after Luna's death, she joins her dear Twilight to make one last memory until daylight comes.
My first, and likely only, one-shot (because I despise the things). Just a (hopefully) cute/heartbreaking story I thought of while sitting in the car and driving from Iowa to New Mexico. It was hell, but I got a lot of stuff done.
If you didn't like it, you could be kind enough to tell me why- that will really help improve my writing in the future. Or, if you really are that one person who just really wants to be a jackass, screw off and don't read it.
