So, by now I'm sure most of you have seen this already, but it would be remiss of me to not link what may be the single greatest Luna fanwork released.
It was fun to watch the progress this video made to its final release, and the product clearly reflects the time and effort put into it. It is utterly gorgeous.
Enjoy, our Children of the Night

P.S. I felt it appropriate, so I changed "Ponies of the Republic" to "Children of the Night." The folder is still for Luna or Republic related ponies, it just has a better name.
