Throughout his lifelong career as a successful author, people could swear that "Leroy Cousineau" literally lived the adventures in his "Equestria Series Books" before writing them out for the world to read. Easily afterwards, Leroy's magnificent works earned him worldwide respect, unimaginable wealth, along with much more. His little ideas of a fantasy land filled with magic, heroic ponies, villainous dragons, so on, evolved quickly into one of the most recognizable franchise empires in the modern world and remained such until his dying day. Now, with him regrettably deceased, where will his series go without him? Over? Under?

Its future is actually left in the hands of "August", his artistic grandson. Yet... it was clear that Leroy was special. He had a gift. One that his worried grandson fears, despite being told otherwise, he doesn't have. What was the old man's secret? Did he indeed live out his adventures before writing them? When August inherits the ancient family book entitled "the Journal of Equestria" and is literally warped to the Crystal North when reading its contents, he finds out the answers he needs to writing well... and also discovers that a certain tyrant of a former unicorn king is hell bent on traveling back to his opened world to form an army.

Not if the Crystal prince and princess have anything to say about it, however...
