Astria has medium length brown hair and eyes, she is 4'9, has fair skin, and is skinny.

Astria is very kind, caring, clever, and funny. She has many friends, and nearly all teachers love her because she is a pleasure to have in class, is respectful, and is a top student. She is not a rule-breaker, however, she is slightly mischievous at times, but does not get caught. If she does, the teachers usually let it go because it is something small. Astria is known for her smarts, kindness, and humor, and is considered fun by her peers. She likes to wear a matching bow with her school uniform and outfits. Her favorite hobbies are reading (she loves murder mysteries, thrillers, horror, and fantasy), writing, listening to music, playing her instrument (flute) and drawing.

Her mother (Autumn Raine, nee Isolde) is a pureblood and her father (Ender Raine) is a Muggle-Born. She was raised around both the Muggle and Wizarding world, being very knowledgeable about both. She has 2 younger siblings, Celestia Raine (9 years old) and Zane Raine (7 years old).

Her first instance of magic was when she was 3, and was playing the bathtub with a rubber duck. She made the duck swim around on its own, by accident as she was playing. Her parents were thrilled knowing their daughter was a witch.
