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.
She used to attend Royal Preparatory Academy. 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.
