->''"We will watch over the children of Earth,\\
Guide them safely from the ways of harm,\\
Keep happy their hearts, brave their souls, and rosy their cheeks.\\
We will guard with our lives their hopes and dreams,\\
For they are all that we have, all that we are, and all that we will ever be."''
-->-- '''Oath of the Guardians'''

A series of books by Creator/WilliamJoyce (writer and production designer behind ''Disney/MeetTheRobinsons'', ''WesternAnimation/{{Robots}}'' and ''WesternAnimation/RoliePolieOlie''), ''The Guardians of Childhood'' tells a sweeping tale of the ongoing battle between Pitch, lord of nightmares, and the eponymous guardians, consisting of figures such as the Man in the Moon, [[SantaClaus Nicolas St. North]], the Tooth Fairy, Bunnymund the EasterBunny, the Sandman, Mother Goose, and Jack Frost.

A film by Creator/DreamWorksAnimation, ''WesternAnimation/RiseOfTheGuardians'', was released in November 2012. Taking place many years after the team's formation in the books, it tells the story of Jack's recruitment to the team.
