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...

It's been a year since the day Twilight Sparkle learned what Star Swirl the Bearded couldn't, since she found out that friendship can truly conquer any trial, since she was announced as a princess of Equestria for creating new magic. During then, the times seemed happier for everypony. Now, however, darkness has returned... and it's influence is stronger than ever. Mysterious Everfree Forest threatens the ponies as do the swarming changelings in the badlands. In southeastern Vallhalla, the formerly allied dragons fight one another. Then, there are the eastern Zeklathine isles, the mightiest realm of the griffins... lost completely due to evil.

As her first anniversary as a princess nears, Twilight cannot keep from confronting these troubles. Everyone clearly needs aid. Yet, where can she get the needed help? From a forgotten other world, a forgotten other people? Perhaps. Join her as she calls to the stars... and get's her answer. A "Humanity will return to Equestria" story, if you will.

"It is when the sun is shining its brightest, when the moon is at its fullest, when the Elements of Harmony have been born anew and Star Swirl is amongst us once more... that there shall be a most remarkable sparkle of twilight. And from that twilight, from a place long thought as lost, from we who have been forgotten, a child of history will be brought back home as well as a millennium old prophecy will finally be fulfilled."
