Priestess
The silent voice within one's heart whispers the most profound wisdom.
There's already been a picture here called (High) Priestess, I know. I'm cheating. Other pictures in this series of design/conceptualisation for Twelve Thousand have all had the same title theme anyway.
At some point I wasn't sure if Gwen was Priestess or not. That's what she was originally, but then I thought to see if there was something more fitting because the title alone just doesn't sound like her. I was inclined towards Wheel of Fortune for cruel reasons, but decided that Priestess worked after all. I still kept the wheel though.
