SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

A Soot-Covered World, book 1.

Princess Celestia has been keeping a dark secret from her subjects for a very long time.

It's not an easy truth to tell, but if anyone can accept her after learning it, it will surely be her most faithful student.

This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.

My unicorn parents called me a worthless mud pony. They pushed me every day to overcome my lowly status. When I woke up one morning with my cutie mark, I thought they would love me. I couldn’t have been farther from the truth.

It was not destiny or enjoyment that led me to discover the cello and composing. My parents made that decision, deciding before I was born I would continue their family legacy of famous musicians.

They did not realize what that decision would cost them.
