Princess Sofia is the humble protagonist of the series and a girl of humble origins who lives with her mother Miranda. She becomes royalty after her mother's remarriage to King Roland II. Being new to the entire princess legacy, she had hard times understanding other princesses, and acting like one.
As Sofia becomes a student at the Royal Preparatory Academy under the guidance of the Headmistresses: Flora , Fauna and Merryweather , good friends of Princess Aurora , she has been taught about what being a princess is all about. Sofia was initially clumsy, but has a pure heart and though she was originally a mere commoner, she retains a very carefree personality and was once seen to enjoy sliding down the rails of the staircase.
Her behavior often puts her at wits with her stepsister Amber , who's apparently jealous of Sofia, especially when she first came to live in the castle. Often at times, Hildegard is a little thrown off by her personality. A mermaid named Oona became good friends with Sofia because of her kindness. A witch named Lucinda befriended her for the same reason.
However, Sofia occasionally becomes discouraged or frustrated, and can't get things right the first time. This is when her friends, such as Clover , help encourage her to do her best. Sofia is a friendly person and encourages others to get along, but prefers hanging out with two or three people rather than being around crowds.
Sofia is also very adorable to the point where some new acquaintances smother her with affection as shown in " The Secret Library: The Tale of the Noble Knight ". Sofia is a young girl with fair skin, rosy cheeks, thin pink lips, light blue eyes, and shoulder-length wavy auburn hair that she sometimes ties in a ponytail. She usually wears a princess gown of a lilac bodice trimmed in two lines of pearls down the front and along the neckline and wings on the skirt, a pearl-hemmed and studded lilac petaled skirt with a row of great lace drops and trumpets each arranged like a four-leaf clover or cross on a nimbus, and a yellowish petticoat with a lilac band; a swirly tiara inset with pink sapphires, white pearls, and a turquoise diamond; violet slippers with bows and mid heels; and the royal family's Amulet of Avalor , a huge fire opal drop cabochon on a swirly silver backing topped with three sapphires and on a silver necklace wrapped over amethyst beans.
