Aylin

Aylin is the alicorn daughter of Princess Luna and an unknown stallion, and the current Princess of the Moon.

Once praised for her magical talent and strive to improve Equestria, Aylin eventually turned on the ponies she loved to create what she felt would be a better Equestria. Despite her original goal, she eventually began to develop more questionable morals, and distanced herself from the rest of the Mane Seven.
