Live Action Model: Actress Radha Mitchell
Christina Sawyer is the (adoptive) sister of Charlotte Sawyer, one of the daughters of Heptamera. She is very important to Charlotte, one of the people she felt really loved her in life. Christina has now grown up and had a family of her own (her married name being Riddle), and tries to run her horse ranch in peace. But she may never put the sinister legacy of her sister behind her.
Thanks to my friend ducky for volunteering her last name for Christina's married name.
