He put all of the ponies into slavery but before that StarBerst was born on April 11 as a pegasus and lived in a small village at the east edge of Fantasia with her mother,father,older brother,older sister,younger sister,aunt,grandma and grandpa. She had a birth defect where her eye was a different color Than the ether one, and she was the only one that didn’t have a cutie mark at her age so she was bullied and, got called names, and sometimes she would come home crying she never told anyone about this she would always say that she fell down a tall hill her family believed her because she always told the truth. But one night she decided to fly her sorrows away. She was flying really fast for her age she flue down and flue up really fast it made a boom sound and she saw the stars start to fall, her hole family woke up and whent out to see what was going on.
