From the description:

“The primarch of the Empress’ Children, Rarity, had always enjoyed the finer arts of civilisation and culture of her people such as art, music and celebration. There was little point in befriending the galaxy if they could not indulge in these civilised traits. Notorious for her quest of perfection, Rarity believed that Ponykind was the perfect creation and all should strive to emulate their Empress.

Greatly angered when her goals are challenged, will the quest for perfection prove fruitful, or will it lead Rarity down the path of Discord?”

DUUUUUUUHHHHHHHH, I DUNNO GUYS, WHAT DO YOU THINK?
