Matilda, or Tilly for short, is the duchess of the kingdom of Enchancia; she is the older sister of King Roland II. She lives in her own manor house somewhere away from the royal castle. She also acts as a mentor to her step-niece Princess Sofia, who now possesses the Amulet of Avalor, like she did when she was younger, and reveals to Sofia the Secret Library, which contains unfinished books of lives that need helping.
A portrait of her is on display at Royal Preparatory Academy, showing that she used to attend. When Tilly lived at the castle when she was younger, she used to have Sofia's bedroom, where she would spend her time reading The History of Enchancia Castle. She found the Secret Library thirty years before Sofia did, becoming a story keeper and finishing stories of books that did not yet have an ending, involving a life that needed helping.
She was enjoying herself at Cordelia's sorceress ball, but was told to stop by King Roland I, as it was not an appropriate way for a future queen to act. But she didn't become queen, as her brother, Roland II took the throne, instead.
On her first visit, it was the first time since Roland II had remarried to Queen Miranda. Roland wanted Tilly to make her special apple pie, but she would only do it if she had some "little helpers." Not wanting to go through the same boring ordeal again, Amber and James got out of it, but Sofia, not wanting to be impolite, got talked into it. They needed to get Arabella apples which took them on a vast trek to try and get to the orchid, which didn't stay in one place for too long. It turned out to be quite the adventure for Sofia, which she thought was "whiz bang," as Tilly would say.

- It's unknown why she gained the title of "Duchess," as she was born "Princess Matilda," meaning she should've ascended to the throne before her brother.
