Original Description:

This design really isn’t good lol

She is the first part of my cosmic ponies series.

She is the sole survivor of a powerful cosmic race and was the search of a new home. Years later after swimming in the ocean of stars she had found Equestria, a planet filled with joyfulness. Seeing their dominant inhabitants, she disguised herself as pony and adopted the name “Stellar Diamond”. Though it may look like it, she is not a princess. She wears regalia in honor of her parents, who were strong warriors. No one knows what her real name is or what her true form is. She doesn’t like reflecting on her past. She is strong, with a number of abilities. Due to her “young” age, she is not as powerful.
