20 years ago, an asteroid struck the planet and caused widespread destruction. As affected nations across the world struggled to recover, Gryphus, the land of the Griffons, faced an internal conflict which resulted in the Kingdom falling into the hands of Ultranationalists. In an attempt to gain more resources for national recovery, the new Ultranationalist government launches an invasion across the ocean to invade Equestria and take its resources. It is up to the country's air force and foreign mercenaries to defend Equestria from the attack. This story is told based on the accounts of different aces.
