i think that after the tribes settled equeastria they started to experiment with magic and biology trying to create a powerful breed of pony i think chrysaliss and discord were there first attempts and were labled as hideous failures and were set to be killed but discord saved them both and enslaved the ponies it was then that celestia and luna were created to imprison discord but they somhow missed chrysalis and she came back to exact revenge for her brother /// discord and chrysaliss didnt ask to be born they cant help what they look like we should feel greif for these poor souls
I really don't think that Discord, Chrysalis, Celestia, and Luna were artificially created. Discord is a draconequus and Chrysalis is a changeling. Neither of them are ponies. Obviously there must have been more changelings other than Chrysalis. Because there were thousands of them that invaded Canterlot. How else could those changelings have been made. If Chrysalis was a failure, they wouldn't make more of the same species. Besides, there is no way to experiment. Celestia wasn't born yet, obviously. And since Celestia is over a thousand years old, this would mean that the tribes settled Equestria in the year 1000 A.D. or earlier. And in that time, there was no knowledge of science so they couldn't have experimented. It's a nice theory, but too many things contradict it.
auuuuuu, when she was smaller the other shape sifters expected so much from there young queen, vengence on the rest of equestria, and plots of distroying the world, no one should b dragged into that at a young age, and it eventually tore her to peaces!!!
