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
In "Forever Royal", the Secret Library was created centuries ago by the Narrator the very first Storykeeper and he filled it with many books that remained unfinished.

Thirty years ago when Tilly was still a 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. Sofia accepts the job and begins going on missions, starting with freeing Minimus's brother, Mazzimo. Nearly all of Sofia's missions so far involve some kind of personal element to her, whether helping a friend or reforming an enemy.

Completed Stories
Throughout Sofia's job as Storykeeper she has completed six stories so far:
