Hey peeps! I realized that joining you guys on this ride would be an awesome experience so here is some of the blocked out character:
The direction I'm envisioning Is that she was once a treacherous queen who has been punished to a puppet life. Her legs/hands are crystallized to symbolize immobility. The floating head entity is who is in control and will be doing all the movement. She just floats along. The stone is where the curse is held.
So far, the chained up limbs seem underwhelming so I'm gonna be working on a way to make it more interesting!
Have fun guys.
