This story is a sequel to Rainbooms and Royalty

Alternate Universe (Dashverse): A continuation of "Rainbooms and Royalty" Ponyville goes to sleep one night only to find in the morning that every foal in town is gone! The ancient evil King Sombra has returned and stolen foals from all over Equestria. But why? What is his true purpose in stealing them? It's up to Rainbow Dash and her friends to rescue the foals and stop this evil once and for all. But it's a long journey and complications arise with the ponies that join them. How can they save Equestria and preserve harmony when there is disharmony among their own ranks?

Twilight Sparkle, Princess Celestia's most prized and faithful student, is being sent to Ponyville to learn about the magic of friendship.

And she's not happy about it.

Letters. Everyone writes them, and they're not just for ponies. Be they carriers of serious news, friendly correspondence between pen pals, or declarations of heart and heartbreak, each one is written with a clear purpose or goal in mind.

Celestia uses them to try and keep her faithful student and friends in line, and try to keep an unbalanced world on the straight and narrow.

This is much harder than it sounds.

Now with an audio reading by Lady Tenkage!
