Prince Shining Armor and Princess Cadance with their daughter Princess Skyla.
 
Princess Skyla was born as a pegasus, just as her mother had once been before she transcended into alicornhood. Skyla was also born in the Crystal Kingdom, but due to being a regular pony, she was not a crystal pony. Skyla is very much like her father, being the “girl-next-door” type, but she also has her mother’s loving manner and unshakable calm. It’s not very surprising she transcended into an alicorn after stopping the last remnants of Sombra from attacking, using the love of the Crystal Ponies to create and aurora borealis to ward off the darkness.
