Everypony hates war. This much is clear. For the past thousand years, peace has reigned in Equestria. Thanks to a clever combination of diplomacy and the threat of military action. But now, a new threat surfaces. A rift is forming, and civil war is brewing. I'm assuming that you know of the Mane Six and the events of Season 4. If not, SPOILERS!

The year is 1806. The Corps of Discovery, headed by the legendary explorers Lewis and Clark, is currently holed up in Fort Clatsop. However, their presence in ancient Griffon territory does not go unnoticed. Meanwhile, in Equestria, Celestia and Luna sit comfortably on their thrones. They never could have seen it coming, but the ideas of the West were about to descend on them.

The crew of the Enterprise has seen many foes and defeated them all. But when an unfortunate encounter sends them hurling across space and time, they are forced to make contact with a species ripped straight from Earth's mythology. Unfortunately, an unstable political situation may get them involved in an ongoing war between two rival factions.
