Princess Celestia: [Smiles Warmly] ...Have no fear my dear, It's all about you.
I haven't post anything for a long time so... ;)
In story, Luna has been banished to the moon. It's about 1000 years of imprisonment. At least, she has been returned but not exactly as Nightmare Moon.
I've seen a lot of other art about Princess Molestia, Gamer and Naughty Luna... that inspired me to create this piccie <3
Made in Sai and Photoshop CS6

So YOU'RE the one who drew this. Could never track down the source before. One of my favorites.
