Original Description:
 
Glowing Muse. Rarity’s Duplicate. She is the inspiration that motivated rarity to create her best outfits.  
Now that her inspiration has come to life, the original feels empty and out of ideas; a situation that only lasted… a few days.  
Her hair on her right eye wears it, not only to hide the fact that she wears false eyelashes, but also to hide her eye from Nightmare Rarity, the one she uses to cause illusions to others. Something that Muse takes advantage of for her benefits.
