2022 REWRITE IN PROGRESS

After being rudely awoken from Cryo-sleep, John-117 finds that the Forward Unto Dawn has been sucked into a gravity well, causing it to fall towards an unknown planet. In the crash, he is separated from Cortana and falls alone into the Everfree forest. In addition to this new complication, old memories from a scarred and tragic past haunt his dreams, putting his remaining sanity on edge.

However, he has little time to ponder these thoughts, as he encounters the planet's... peculiar... inhabitants.

"My life has run its course; I've planted my hooves firmly on the ground and ridden the ups and downs to my greatest potential. I've loved, I've hated, I've cried, I've laughed... but most importantly, I've overcome."

A simple life, floating on the wind.

Brace down and buckle up as you are taken along on the wicked rollercoaster ride that is Vinyl's life. Stand beside her as she first learns of her talents as a musician. Hold her hoof as she braves whatever life throws at her while buskering on the streets of Manehatten. Cry with her as she faces old fears and overcomes new ones. Cheer and revel in her marriage and success. Laugh wholeheartedly at her comedic small mistakes and happenstances.

Most importantly however, understand the rocky and twisted road that shaped the DJ we have all come to know and love.

It is the summer of 2020. The popular TV show "My Little Pony: Friendship is Magic" has finished its eighth, and what appears to be final, season. In the wake of increasingly violent attacks by an extremist Internet-based terrorist group, the founders of the popular pony site, Equestria Daily, decide enough is enough. Bronies from all over the world have gathered in a small, abandoned industrial park in the run-down outskirts of Chicago to find the culmination of their dreams: Equestria. Through the wonders of science, they flee Earth for a land of magic, mystery and secrets. They will be weighed, they will be measured... will they be found wanting or will their dreams come true?
