A Twin Canterlots story—third in the Brass Ring series

Spike, number-one assistant, is happy to seal up and send off Twilight’s correspondence through the portal, where Sunset will take care of mailing it. He follows the instructions he’s given to the letter. Too bad he missed one critical point. . . .

Takes place about ten months after “Through the Mirror” and four months after “Rainbow Rocks”—late in season five.

Inspired by a comment from FanOfMostEverything on Amphorae—specifically, Twilight’s letter making up the chapter “Epistolary Interlude”.
