Fallout Equestria: Forgotten Days is a side-story based on Kkat's Fallout Equestria creation. The story takes place roughly two years following the major events of Fallout Equestria and the effects are starting to be felt throughout the Wasteland. But change takes time. And in the Northern most corner of Equestria the once proud Crystal Empire still remains as brutal and violent as ever.
The story opens on the morning of The Last Day. Shimmer Jubilee finds herself scrambling to live and safely enters a Stable. However, it is not as it seems. Emerging from Stasis 200 years later, Shimmer finds Equestria a changed land filled with violence and hate. Her journey is only just beginning as she ventures forth with a Unicorn named Rocket and an Earth Pony named Zephyr.
