Serenity is a wonderful caring wolf, even if she is one of the kings gurads. She has to hide a lot of her feelings and act mean when around the king. But when she's not, she's reading or telling fairy tales to the kingdom's children. She'll be needing a rough female voice but can also sound sweet as a mother. 
She can have a sweddish accent, but anything else is fine aswell! <3
