Abigail has long, platinum blonde hair, soft grayish blue eyes, and very pale skin. She is a bit short for her age, around 4'6. Her hair is usually done in a neat braid to keep it out of her face. She doesn't wear any type of makeup unless it's a special occasion, and even then she keeps it to a minimum.

She is a brave, determined girl who never backs down from a challenge. She's quiet and flies under the radar most of the time, but she isn't to be underestimated. She is very talented when it comes to magic.

She is a pure-blood, so she's grown up around magic and lacks knowledge about muggles and their culture. She comes from a somewhat well-off family, and has always been a bit spoiled. However, she is still humble and grounded as her parents have taught her to be. Before coming to Hogwarts, her parents home-schooled her and taught her basic things such as reading, writing, etc.

Abigail's first instance of magic was when she was 6 years old. She had been playing in her room when her older sister came over and stole her toy. She got particularly upset and in her anger, trying to get her toy back, a book suddenly flew off the ground and knocked the toy out of her sister's grasp. She remembers being very confused, wondering if she had done this as she stared at the now motionless book.
