Would you mind me using this in an April fools ponification of www.gnomestew.com tomorrow? We are a gaming blog that has won many awards and we wanted to do a ponification for the day. I found a version of this where someone added captions to turn this into a D&D, but I wanted to get permission from the original author first. - John Arcadian
After seeing the prologue comic so far I think Celestia used the elements of harmony as some kind of WMD against the invading Griffons and that caused the main 6 to be trapped in some kind of darkness and Celestia has to stay there as well to keep them from dying in the darkness so now Luna has to protect Equestria from the invaders by herself.
"Some kind of darkness" is space, the night sky, where the stars are, Luna's prison, and where AJ's parents are. The EoH are a constellation of 6 stars at the moment, and a 7th in the middle is Celestia, keeping watch over them until they snap out of it, if ever. Which leaves ponies on Equestria in a bit of a hard way to go, since Celestia's too busy to raise the sun. In fact that 7th star probably IS the sun. It's a bit far away to warm the land now.
