Three hundred years after Luna's banishment, an uneasy peace has collapsed and war erupts between the United Tribes of Equestria and the growing Gryphon Empire, who seek to supplant Princess Celestia as ruler of the heavens and claim the rich lands of the pony nation for their own. With the border defenses shattered, Canterlot endangered and the armed forces unable to stem the onslaught, who can stop the relentless Gryphon war machine as it overruns province after province, scoring victory after victory as it closes in on the Equestrian capital city?

In this time of peril, when the entire pony nation teeters on the brink of defeat, a champion will rise to lead the resistance to the gryphon invasion, becoming not just the commander of an elite force, but a symbol of Equestrian valor and fighting spirit. A born warrior and leader, the name of Firefly will be one day revered as not just the founder of the Wonderbolts, but as Equestria's greatest hero...

Taking place seven hundred years before present and canon to both the Gentlemanverse and Turnabout Storm novelization, this is the story of Rainbow Dash's ancestor, the founding of the Wonderbolts, and their role in the bloodiest conflict of Equestrian history. It is a multistory Magnum Opus consisting of several discrete stories, as described below:

Book 1: The War Begins

The Gryphon Empire invasion of Equestria launches at dawn with an all-out assault on the Equestrian Army and Aerial Corps border bases, accompanied by deep-strike raids against Cloudsdale and the Royal Guard training base of Fort Spur.

Will Princess Celestia unleash her enormous power to end the war quickly? Can Outpost Epsilon withstand the onslaught long enough for the much-maligned Royal Navy to reach them? And can the civilian populace of Cloudsdale resist a massive and determined air attack by the Imperial elite against its all-important weather factories and storm cloud production facilities?

Book 2: Rally and Recover

With the border defenses crushed and the remains of Outpost Epsilon evacuated, both sides lick their wounds, hastily reorganizing and preparing for the next Imperial offensive aimed deeper into Equestria.

Can missing Cloudsdale be located near the borders of Thestralslovakia? Will the once-disloyal and still-distrusted bat-ponies that live there side with Equestria or the Empire? What is the Imperial invasion plan? What role will the Changelings play in the conflict? And what will happen when a sixteen-year old gryphon cub faces off with the gryphon-hating pony named Thunderbolt; one of the most lethal and bloodthirsty beings to ever live...?

Book 3: Second Offensive

While the fate of Cloudsdale is negotiated and Firefly's forces prepare for additional action, the second Imperial offensive begins with an assault against the badly outnumbered Equestrian Army at Maresk two hundred miles inside Equestria, attempting to pocket and destroy the thousands of sorely-needed soldiers based there.

Can an out-of-favor earth pony Colonel rally his regiment to save the city and an entire Army Corps? Or will the city's soldiers and civilians alike face the fate of the border bases, becoming yet another crushing defeat in the Imperial drive on Canterlot?
