Sona, Maven of the Strings

Overview

Sona is a post-beta release character for League of Legends. One of the games few characters built purely for support, her main abilities have an effect on use, as well as providing a passive aura that buffs her and her allies.
 

Backstory

Sona was an orphan, born and raised in an adoption house in Ionia. Unable to speak, Sona waited in the adoption house with the only thing left with her as a baby, a grand instrument called an etwahl. One day a wealth Demacian woman heard of the etwahl's existence, and traveled all the way to Ionia to seek it out. Upon finding it and Sona, she immediately bought the instrument and adopted Sona, teaching her how to use the etwahl's abilities to their full potential. She eventually learned how to manipulate the etwahl to produce not only beautiful music, but deadly attacks.
