A Farewell letter to Derpy Hooves written by Doctor Whooves, explaining why he was not there during the fall of Cloudsdale or after that in the Fallout Equestria Universe.
DanielScratchAnimations has made an audio reading of the first chapter. It can be found at https://youtu.be/tVgQLM6HrQI.
For any reader who is thinking about audio adaptations, two individual groups are working on versions. I'll attach links when they are done. I am not interested in any other adaptations being done.
