Who is Orielle from Heir Apparent and what is their importance?

Orielle is described as beautiful, coordinated, polished and gorgeous, and her specialty is potions. Her childhood was troubled and difficult, as her father had run out on the family when he discovered that she was marked with a pentagram on her palm, which identified her as a witch. Her mother tried to drown her when she was seven, and from that point on, she was raised in the gutter. Janine earns Orielle's respect by plunging into her new life head first, without shirking duty or drama, and without attempting to use her femininity to advance her cause.
