Somber Lullaby

With a broken voice, Lullaby learned to funnel her love of music into her magic and has created melodies without need for an instrument. Does not consider herself to be a princess of any kind and is simply content traveling with Peachy Melody.
She pulls the wagon when they move locations and has to tuck her wings close to fit inside when it's time to rest, but she honestly doesn't care enough to bother bugging for something bigger. Seems distant yet in reality she just has no idea how to talk to other ponies after isolating herself for hundreds of years.
