53 Years ago: The seafaring nations of Unity had achieved the golden age of sail with the maritime economy booming from a heavily established maritime infrastructure and holiday-goers traveling the world on luxurious ocean liners and transcontinental zeppelins. Equestria was the world's leader in possessing a powerful navy to protect the vital sea-lanes from marauding pirates and keeping rival states in check by keeping fleet numbers above those of their northern Gryphon neighbors.

One day, everything changed when vast fleets of unknown warships appeared across the world who would reveal themselves as the Equestrian Fleet of Fog. Chaos and total destruction raged across the world as these highly advanced and self aware vessels began attacking ships and establishing blockades on a global scale. Princess Celestia attempted negotiations with the warships and sent the Elements of Harmony to intervene only to have all but two members killed and her entire fleet destroyed in a final great naval battle.

Devastated and infuriated with the loss of her nation's protectors, Princess Celestia declared war on the Equestrian Fog ships which would span over half a century.

Present Day: Admiral Ruby New Moon, a veteran 'Tin-can Captain' turned fleet commander has been given command of Equestria's newest fleet of warships thanks to the assistance of Humanity as they too wage a war of struggle against the Earth-based Fleet of Fog. Under executive orders from Princess Luna, Admiral Ruby sets sail with her mighty fleet to hunt down the Equestrian Fleet of Fog's flagship who was responsible for the deaths of four members of the Elements of Harmony. What follows would be the beginning of one of the greatest and most dangerous deployments in Ruby's career or her last.
