Rarity is not an adventurer.
When a mysterious sword falls from the sky, her first thought isn't that fate is calling her to a quest, it's that the sword is a masterpiece. Still, at Spike's prodding, they both go out to seek where the sabre came from, as Spike is worried the fate of Equestria hangs in the balance. All the same, Rarity isn't so much interested in all of that as finding out who made this wonderful work of craftsmanship.
Because Rarity is not an adventurer. She is a designer.
