Sarah Heathcliff is a burnt-out but caring girl, the founder of Bythorne Paranormal Society, or BPS. She grieves over her older brother, Mark, who died to an alternate, and blames the Police, especially Thatcher, for it. She works with Adam Murray and Jonah Marshall at BPS, and is friends with Evelin Miller. She has dark brown hair and eyes, wearing a black hoodie with a BPS logo. Sometimes she gets impulsive with decisions and is prone to lashing out, but she still genuinely cares for others.
