The whole musical extravaganza was put together by Matthew Mercer (School of Thrones, There Will Be Brawl), with music by Jason Charles Miller.

The fantastical fairytale takes place in Serenadia, in a world where singing is power. In the aftermath of a terrible war, the losing side now find themselves “muzzled” — unable to sing, and therefore powerless to rebel against the royal family.

Main character Mafalda (Burch) is one of the unfortunate muzzled souls, but she really wants to sing. Will she find a way to break the curse?

The first episode is now online, and we guarantee the catchy songs will get stuck in your brain! Enjoy:
