1002. Following a successful attack against Canterlot, the sudden changeling invasion strikes hard. Although the Element Bearers and the Princesses managed to escape, the tide of insectile horses ravages Northern Equestria.

In response, the nations of the world, including the Avalon Republic (a human nation), declare war on the Changeling Empire, and muster troops. Across the southern stretches of Equestria, changelings battle an alliance of ponies, humans, griffons, hippogriffs, zebras, and Saddle Arabians. Millions clash in trench warfare that extends from the San Palomino Desert to the Hayseed Swamps. The prize; a continent's enslavement or it's freedom. But which side is more willing to make the final sacrifice?

Will have references and uses of weapons in Battlefield 1. Is partially inspired by the Great Martian War of 1913-1917, a fictional but serious documentary. Story is written as a historical narrative, with some third person points of view at some points.
