Every night precious cargo is shipped out of Equestria up North to the Griffin Kingdoms. Unbeknownst to even Celestia herself a great many ponies are beggining to conspire against her. In every city, every town, conductors transport the valuable workforce of Equestria up North. A booming economy has been built upon the hairless scarred backs of its slaves. It is time for a change, for how could any benevolent ruler approve of such subjugation? We follow the story of one such conductor on the Underground Express and the role she will have to play in dethroning the Sun herself. Would you rebel against your loved ones because of their wicked ways, or would you accept them with all of their faults?
(This is my first ever story, so criticism and comments are welcome!)
I'm guessing the humans are the slaves?
Also, in your description: it's 'beginning', not 'beggening'.
Finally, there are some grammar mistakes here - particularly in the middle bits.
814233 Thanks for that catch, and ya this is set in an alternate universe with human slavery.
I'll read it later when more chapter will be done.
