I have hear an good Explaination, why Luna is the stronger of the Sisters:
Celestia rule over the Day and the Sun, while Luna rule over the night, the moon and the Stars.
Every Star is a Sun, so Luna controll all Suns, except the only one her Sister can control.^^
I still wonder why so many are creating Art of Daybreaker but so less of Nightmare Star.
Daybreaker was a Fear Imagination of Starlight and Nightmare Star is from the Trading Card Game.
Personaly I think the later Nightmare Star Design look far better as Daybreaker:
Celestia rule over the Day and the Sun, while Luna rule over the night, the moon and the Stars.
Every Star is a Sun, so Luna controll all Suns, except the only one her Sister can control.^^
Glory to the sun
