So, Lightybulb, an amazing tumblr artist, ( http://lightybulb.tumblr.com/ ) posted on her "ask Luna and Rarity" tumblr blog ( http://ask-luna-and-rarity.tumblr.com/ ) that she couldn't find any RariLuna fics, and that she really wants one. I haven't made a fanfic in a while, and I was dying to do one. So, I decided to make one for Lighty!
How Rarity and Luna became good friends... and then some! Pretty short, and I'm not planning on going on any further. Have a good read!
