Here, I'm having trouble trying to find a story I really like, it's a RarityXLuna story, Princess Celestia is like ruler of heaven, and Luna is ruler of the dead, Luna having trouble getting the ponies of her realm to like her, and Rarity helping become more liked, Rarity, Applejack, and Fluttershy serve Luna, and Rainbow Dash and Pinkie Pie serve Celestia. Does anyone knew about this story?
