Katherine/Tall Kathy/ Kath Williams is a half-blood girl who enjoys cooking, watching television and horse riding. She is gentle and giving, but can also be very lazy and a bit greedy.

She is English. She is currently at Hogwarts.

Physically, Katherine is in pretty good shape. She is tall for her age with fair skin, black hair and greenish eyes.

She lived in an upper class muggle neighbourhood. Her mother walked out when she was 6, leaving her father, an artist called Johannes, to look after her.

Katherine went to Bash Street School, where her favourite subjects are drama and music. She loves her teacher Mr Wilkins but hates Mr Doyle whose interests include looking like a tomato.

Katherine's best friend is called Leia Higgins. They get on well most of the time. She also hangs around with a girl called Cheyenne Henderson and a guy called Tom Harper. They enjoy reading together.

She also has a severe phobia of bridges. Once she fell from one and didn't get hurt. Neither a bruise, nor a scratch. Her parents felt amazed she had magic, but she was still scared.

She's quite dim-witted, since she has 62 IQ.

She likes popsicles, badminton, duck herding, football, theatre, travelling, watching television, sailing, finger painting and podcasting.

She's clever, cute, dazzling, dear, entertaining, extroverted, fashionable, fresh, fun, good-looking and outgoing.
