When Twilight Sparkle returns to Canterlot to celebrate the Grand Jubilee with Princess Celestia, she again meets the prank-loving Princess of the Moon - but what does the mischievous Luna want with her? And what do socks have to do with it all?

Special thanks to Canterlot-expert TwilightFlopple for not only inspiring me with her sexy pic of Luna in socks http://twilightflopple.deviantart.com/art/Luna-s-Socks-227462669 but also for helping me come up with a DJ-PWN3 song, a room opulent enough for Equestria's capital and a Griffon King with a suitably epic name. Thanks!
