This is a fanfic of the Fallout Equestria universe. It has been 23 years since the Last Day, when the once peaceful zebra empire and the kingdom of Equestria exchanged megaspells in their mutually assured destruction. Stable 68 Security Chief Flag is forced to leave his secure underground home in its defense. But when he emerges into the irradiated lifeless Wasteland, Flag finds that he has become a critical part of the beginnings of a new war between his world and the stars. The oncoming storm is feeding off the physical, military and political fallout of the Great War and Flag's struggles to accept his lineage, his belief in a divine power in a hellish world, and the origins of alicorns. While the forces of a conflict that would horrifically outshine the Great War marshal in the stars, Flag comes to realize the greater threat has been living in Equestria for eons... and that only he can stop them both.
