Spoilers for our previous installment, The Mask of Tragedy, in this description, so please read our first two fics first.

Rarity, as it turns out, was the Rani! Well, sort of. It's a bit complicated, but Applejack, Rainbow Dash, Spike and the Crusaders can figure it out, right? Right? Best hope they do. This planet the Rani has sent them to is always in a fighting mood...

Meanwhile, Pinkie, Twilight, Fluttershy, Discord, Trixie, Starlight and the Doctor all go back to when Discord returned. A new villain that Discord knows all too well shows up, the musical spawn of an entity that the Doctor also knows all too well. Will the group be able to face the music? Or will this adventure be their swan song? Either way, Pinkie is having a horrible day...

This will have comedic moments and stuff, as well as a lot of darker moments alongside the more lighthearted ones. It's all in keeping with the Doctor Who tradition of playing "Genre Ping Pong" as we like to call it, sometimes in the same story, so expect for tone to bounce a bit from time to time. Death is at least discussed, particularly at the beginning, so keep an eye out for that. Whether or not a character dies is something only time will tell.
