Princess Sage is the second half of the character Princess Cece. Sage is polar opposite of her sister: sarcastic, loud, and not afraid to speak her mind. She comes off as a generally angry and intimidating person, and specifically hates to wear long ballroom dresses (This will be important later on ;) ). Sage could be labeled as a tsundere. She is athletic and impulsive. Unknown to many, she is very insecure (which is why she comes off so mean). She also protects her sister with her life, for she knows that no matter how hard she tries, Solandis will be the next queen. 

I listed Sage as a supporting character because she herself does not have many lines, but whoever will play Cece has the most of her lines. If you'd like to play a version of this character, just with more lines, please audition for the character Princess Cece.

I imagine Sage with a medium/alto voice that is loud and masks insecurity. Since she is a part of a main character (and becomes main later on), please be able to at least carry a tune.
