Dashverse: Rarity and Rainbow Dash are friends, but they don't have much in common. This becomes a problem when Princess Luna needs their help with the Equestria Summit and the two friends have vastly differing ideas on how to proceed.
AU: A retelling of "Sonic Rainboom" episode, set in Dashverse (A universe where Rainbow Dash became Princess Celestia's student. A follow up to "Rainbooms and Royalty")
