Northern "North" Sky had survived a life threatening injury, but it sent him into a coma. Thousands of years passed before somepony found him in the ice. When he finally awoke, he brought only mystery and danger with him, and Equestria hangs in the balance of it all. Now it's up to North and his newfound allies to save their home, all while he struggles to build a new life.

I would like to give credit to the guy who originally came up with the idea: JackRipper. He's an amazing writer, and he's gotten a couple of features. Go check him out!
So, as it turns out, this story has some similarities to the upcoming season 7 finale. Not sure how I feel about that...
