Secret Library

The Secret Library is as an enchanted library that appears in the Disney Junior animated series Sofia the First. From the outside it looks like a tall hollow tree, but on the inside it is a huge library of magical stories with no endings.

History
Thirty years ago when Tilly was still a little Princess, she used to wear the Amulet of Avalor. She used to read a book called A History of Enchancia Castle, and chapter seventeen of that book contained a little blue book that told her of secret passageways in the castle. There was a secret passageway in Tilly's bedroom (which is now Sofia's bedroom), and the amulet turned blue and led her to discover the Secret Library. From that day forth she became the library's Storykeeper, tasked to find happy endings for all the unfinished stories.

Thirty years later, after Sofia became a Princess and was given the Amulet of Avalor and Tilly's bedroom, Tilly hoped to pass the job onto Sofia and gave her the book that contained the key to the Library after her youngest niece passed a few secret tests.
