Miss Eglantine Price is the protagonist of Bedknobs and Broomsticks. She is a witch in training, and is an inexperienced broom flyer.
Miss Price is extremely headstrong, but also very kind when she wants to be. She tries to treat others with respect when they return the respect. She is also absent-minded and terribly forgetful, which becomes a drawback when she has to remember the words to a spell. She sometimes has a lack of patience, due to Professor Browne not giving her answers. Through her adventures with him and the children, she became a motherly figure and enamored with him when his cowardice was shed and his courage was born when the Nazis invaded Pepperinge Eye. When confronted with danger, she digs in her heels and while frantic, refused to give up, and always has a smart remark or quip.
Miss Price is a patriotic woman who lives during World War II England, and is learning to become a First Class Witch so she can try to do her part in the war. Her father was a soldier in the British army and served with the General of the Old Home Guard at Fimi Ridge, and she in turn was well acquainted with the General through him. She signed up for a Witchcraft Course with Professor Emelius Browne, in which she would receive each course through the mail, despite not receiving the final piece of the spell. At first she was reluctant to take in Charlie, Carrie, and Paul Rawlins, but seeing as her house was huge and the evacuation of London's children was necessary, she felt she had little choice and decided to take them in temporarily.
Her spells and magic were made possible with her Poisoned Dragon's Liver, which is the source of a witch's power. The final spell she needed was the power to give life to inanimate objects called Substitutiary Locomotion of which the incantation was embedded on The Star of Astoroth. The Traveling spell she put on the bedknob that was in Paul's possession was actually given to her as a bonus for her taking Professor Brown's Witch College. One of the spells she had the hardest time with was the Toad spell, which resulted in incomplete or temporary white rabbits.
