So, this is Crescent Star. She became Twilight’s student when she discovered a spell to brighten the stars (same sort of thing as raising the moon/sun). During this time, Twilight already had a student (I’m still developing her character/story) who then became bitter at not being the one to find the spell first. She quits as Twilight’s student and becomes a rival against Crescent Star.
While Crescent Star is very knowing about the cosmos, she doesn’t know much about the rest of life. This is the theme of my made up series, The Virtues of Life. Crescent Star’s Virtue is Growth (a lot like Twilight Sparkle). I chose Growth because throughout life, becoming your best self requires growth. These ideas are still being developed, this is just what I’ve thought of so far.
Enjoy! More to come!
