Tavi, aka Octavia Applegate, is an immortal human witch coming from a magical town called Violet Crook. Having experienced the Magic vs Technology war decades ago that shifted how people utilized music or how music is created, Tavi is a wanted woman trying to bring magic no matter what all the laws against magic says. She runs Violet Crook and makes sure that anyone magically aligned is under her protection. She was also responsible for saving a former Trivial member, William "Buttons" Herald, after he was wrongfully killed by his former partner, "The Puppeteer."

As a character, Tavi is very prim and perfect, having a bit of Mary Poppin vibes coming off of her and speaking in a low, British accent. She is very motherly and watches over the band to make sure that all of them are as good as they can be for the musical battles to come. Though, of course, she's a bit war-torn, having been through a long, rough patch that caused her to be a bit strict and demanding.

In the band, she is the bassist. If you want to add a singing demo to your audition, you can, but it is not absolutely needed! If she were to sing, she would be in the alto range.
