Lady Sybil is a very kind-hearted person who is also a political activist. She believes in women's rights and goes out of her way to help a female servant leave her life of service. Her relationship with Grace Foster (the protagonist) is shaky at first but grows into a deep friendship.

Sybil has a mid-pitched voice. I'd like for her voice actor to be able to portray her as a warm inviting person. A British accent is ideal for this role but not ideal.
