Liberty is 5 feet tall. She has long, very slightly wavy dark brown hair that reaches halfway down her back. She has hazel eyes and long eyelashes.

Liberty has always loved reading, and her favourite author is Tolstoy. She is extremely intelligent, witty, fast talking and has an admirable devil-may-care attitude. Usually, she sticks to the rules, because it's less of a bother, but when she doesn't like something, she will not hesitate to bend the rules. She has occasional panic attacks, although she only trusts that information with the most trusted people in her life.

Liberty has lived on the Isle of Lewis in the Outer Hebrides of Scotland for her entire life, with her parents, as she is an only child. Her parents, Vivienne and Theodore Blythe, moved from Canada to Scotland a couple years before Liberty was born. Vivienne is a witch who grew up in England, and attended Hogwarts. She visited Canada on her travels after graduation, where she met the muggle, Theodore. Liberty lives in a small cottage in the capital of Lewis, where she has two cats, Luna and Charlie, a German Shephard, Quebec, and a lot of ducks and chickens. She went to the local primary school and really only had one friend, her best friend whom she had known her entire life, Kingston McEnroy.
Liberty's FIOM was unintentional, when she was five. She was scratched by her dog, but she didn't suffer any damage, not even a single mark!
