!!! Important update !!! - this story has been canceled. I am doing a significant rewrite which I am not going to upload until I finish.
During the writing process, I came up with many ideas that greatly improve the story but because I uploaded it as I write, I was unable to change it. This time I'm going to finish it before I start to upload it. The new story will keep its original idea and core story elements, but with important changes.

Centuries ago, after Princess Celestia banished her sister, she left the throne and went into a self-imposed exile.

Equestria lived, but it changed.

All Twilight Sparkle ever wanted was to study magic, but after King Hearth makes her his new Court Mage, nothing goes as planned.

Thrown into a struggle she doesn't understand, Twilight Sparkle is forced to go on an adventure to find ancient artifacts, make new friends and save Equestria from those willing to bring it to ruin for their own gain.

P.S. Thanks Purple Smart2 for his great editing work!
