"Quiet and reflective, Sona spends her time away from the Guardians as a composer of music... and her time with them as a fighter of incredible power, blasting enemies away with sonically charged starlight. Though she cannot speak, she always makes her voice heard through deeds... or her chatterbox familiar-slash-interpreter, Chiizu". 

In this skin she is a Star Guardian, a group of teenage warriors selected by the First Star to defend the galaxy from threats. Overall, Sona is kind and believes music can bring people together, although she is not above using her music to defend herself (or the galaxy) if necessary.

Part of the lore we have decided is that, being skilled with music which often uses Italian terms, Sona speaks Italian and so a few lines are spoken in the language (usually just one or two words per line). While a native speaker is not required as the lines in question are very simple, it is important to be able to say those lines with accuracy.
