Princess Celestia, the Sun, and Princess Luna, the Moon.
This is for my awesome friend Mark. He's one of my closest bros and a hardcore brony. He wanted to buy a Celestia + Luna Creepy Pony from me but HEY LOOK HE GETS ONE FOR FREE BECAUSE HE'S COOL AND IT'S CHRISTMAS AND STUFF
So yeah MERRY CHRISTMAS MARK HERE ARE YOUR PRINCESSES ALL CREEPY AND STUFF :3
Your welcome, though compliments should go to Mark Kozelek; he did write those lyrics, after all. I just thought that the words and the eerie tone of the song fit the slightly unnerving resonance set by the imagery here. Throw it on top of the name of the song in accordance with the cool hues bestowed upon the Goddess of the night and the name of the band, I couldn't resist.
