When Grand Duke Mark Sayadi Salemsky, Tarkhan of the fleet, emerged victorious in the battle for Khiva and successfully captured the cities nuclear reactor, it began to behave erratically, emitting high amounts of radiation, yet having no effect on the health of anyone nearby, instead it seemed to be charging something... And before anyone knew it, a massive burst of energy was released from the reactor, enveloping the fleet and sending them far away, to the land of Equestria. Now in uncharted territory, completely stranded with no way to contact the romani empire, the duke orders the fleet to set course to locate any potential civilization. Upon discovering the planet is dominated by talking magical ponies, it is decided peace negotiations should begin between races. But that would have to wait, as rebel forces have followed the tarkhan, and they are set on conquering this new land. Of course, the Grand Duke ain't having none of that, as he prepares for a war in unknown skies.
