A werewolf girl, 23yrs old.
She is a professional musician who can play many instruments but specializes in string instruments.
She is the legal guardian of a werewolf child named Avery who has prophetic abilities but is mute - only Sienna can understand her.

When she was a pup, Sienna got separated from her parents and was taken in by a human family who believed she was a stray dog. She stayed with them until her parents found her again and liked the name the family gave her -Maddy - so chose to keep it as a surname.

She is confident in her musical abilities but in all other ways is a fairly anxious person by disposition, and has especially bad separation anxiety from her loved ones as a result of the time she spent lost when young.
