It's been thousands of years since humans and ponies met each other. Of course the ponies didn't know the existence of these beings, until the still young Celestia of Equestria made contact while exploring beyond the Sparkling Sea.

Humans in those days were mighty warriors. Fighting with courage and honour, fighting for their people. And of course, this scared the ponies. Three years after, war broke up between the two species. The two parties suffered great casualties, and the list of deaths was quickly rising. The end of the war was a relief for everyone. Not wanting to revive this horrible event, Celestia made a deal with the Humans. Never set hoof on human soil again. And the humans weren't allowed on Equestria too.

That was thousands of years ago. Now that Celestia faces the threat of war against the Griffon Empire, The Changeling hive, and The United Minotaur Clans. Equestria needs to find allies, but who?
