Only a few years after the Three Tribes were reunified, northern Equestria was the bloody arena of the most terrible conflict in Equestria's history. An alien invasion shook the continent to its core, and hurled its residents into an unimaginable future. The resulting four years of war has forever marked Equestria as the land of the Missing.
Now, on the fiftieth anniversary of the end of the war, we present the definitive account of events, told from the perspective of the harshest critics of all- those who survived it. This is the true story of the Great Extraterrestrial War.
Based on H.G. Wells' War of the Worlds, particularly drawing on the 2013 film adaptation; however, it is not a straight adaptation of either. Takes place after Chapter 4 of Make your Mark, but was planned and written before Chapters 5 and 6 aired, and as a result takes neither into account.
