The Tree of Harmony receives a message from a future Spike to Twilight.
This is a VERY weak spinoff to Fallout: Equestria and is not cannon.
This story includes spoilers to Fallout: Equestria and the Submachine games by Mateusz Skutnik.
Feel free to write a sequel to where Prologue 1 and/or Prologue 2 left off.
I so wish that this wasn't cancelled. It grabbed my attention.
