Those who protect the dreams, hopes, and imaginations of all children worldwide are called the 'Guardians.' They are mystical spirits visible only to the children who believe in them. Their power grows through children's faith; in other words, they live on that belief. The more children believe in them, the stronger they become, but conversely, if no children believe in them anymore, they lose their strength and energy, becoming beings that ordinary people who don't believe can neither see, hear, nor touch.
At the peaceful Santa's Castle, while the yetis are making toys and the Christmas elves are wrapping them, North and the Guardians have gathered in one place at the call of the Man in the Moon.
