Rainbow Dash, a legendary Captain of Cloudsdale, is said to have never lost a single race or fight in her life. Now a Millenium since her death, the Cloudsdale Historical Gazette sends a reporter to speak to the only living witness of the fabled Pegasus, Twilight Sparkle; the former Princess of Friendship. Recalling a particular memory, Twilight happily recounts what exactly in Rainbow's own words, made her a winner.
