From "Princess Luna and The Festival of the Winter Moon" book we can read a few interesting fragments about the conflict that Luna solved that happened between bat ponies who lived in caves and the mountain dragon colonies. Luna was able to solve their conflicts and since I am preparing a story for my own universe about bat ponies in the universe I decided to illustrate this moment.

I have created a younger version of Luna as it was mentioned that she remembered it as one of the first times she’d felt useful as a princess of Equestria. And for the bat pony I design a very simple hair and cutie mark. I might use her in the future as one of the background ponies for my universe. Her colors are based off one of the canon bat ponies from alternative universe from The Cutie Re-Mark episode.

Eventually if you would like to see/use vector of Princess Luna separately you can do so by clicking on this link and crediting me leaving a link to the whole vector.
