The Sandman, or Dream, is one of the Endless, powerful beings who are older than gods and exist throughout creation as conceptual ideas given physical form who was imprisoned by a mortal wizard for over a century. Knowing this, the evil John Dee, also known as Doctor Destiny, seeks to take Dream’s powers for his own so he may become a god-like figure through trapping thousands of people in their worst nightmares.
Soon, Dream escapes and, alongside his faithful sister Death embarks on an epic quest to reclaim his powerful artifacts - a ruby, a helm and a bag of sand - to restore his weakened kingdom, The Dreaming, and stop John Dee from achieving his goals while doing battle with many foes, including the terrifying Corithian.
