GlowStar is the protgee of Asteria or student like Twilight Sparkle (Hey I figured that Asteria would at least have one pony she would teach personally)
GlowStar isn't as talented as Twilight as she can be abit slow at times but she will always pull through eventually.She loves to slack off on her studies as she finds it harder then most unicorns.She lives in Asteria's Castle away from her family
