The Indigo Prophecy foretells the coming of the Indigo Child in Fahrenheit: Indigo Prophecy, and possibly of the Second Indigo Child. The Child will hold the secret of the universe and will grant a single individual unlimited power if he hears her out, but if she tells no one, the world will end. She is also the reason for the falling temperatures in the story and will lead to a second ice age if she fails to tell anyone the secret. The result of telling the secret will determine the fate of mankind for the next ten thousand years. The purpose of the Second Indigo Child serves as the saviour of mankind.
