The real reason Luna became Nightmare Moon

Luna as Leia makes perfect logical sense cuz they're both pricesses, their names have the same number of letters and syllables, and they both start and end with the same letters.

This was originally going to just be a pic of slave girl Luna, but there was way too much negative space and the pic needed something else. Celestia is actually my favorite princess, but Celestia the Hutt was just too funny not to draw.

Here's a pic with just Luna, sized for a 1080p desktop background, cuz people wanted it. imgur.com/SMuzFog
