Artist's comment:

Princess Luna is a major character in My Little Pony: Friendship is Magic. She is Princess Celestia's younger sister and Equestria's former co-ruler, in the first episode of season one, she was the main antagonist of the Season 1, Nightmare Moon, who threatened to create an eternal night. She was later purged by the Elements of Harmony and was invited by her sister to rule by her side. Princess Luna now enters the dreams of her subjects, mostly children, to assist them in defeating their nightmares.

I still haven't watched season 9 or the mlp movie. But I did kinda spoil myself when I saw he Adult Twilight which means the two sisters have past on.... I don't want to see it lol. I'm thinking of dedicating this channel to Luna stuff but I like all the royal ponies. Wish they made a series thats only about the royal sisters before they became Alicorns.
