The Sandman, also referred to as Dream, is one of the Endless, formidable entities that predate the gods and manifest throughout existence as conceptual notions given tangible form. He was confined by a mortal sorcerer for more than a century. Aware of this, the malevolent John Dee, known as Doctor Destiny, aims to seize Dream's abilities for himself, aspiring to attain a god-like status by ensnaring countless individuals in their most dreadful nightmares.
Eventually, Dream manages to break free and, accompanied by his devoted sister Death, embarks on a grand quest to recover his significant artifacts - a ruby, a helm, and a bag of sand - to restore his diminished realm, The Dreaming, and thwart John Dee's ambitions while confronting numerous adversaries, including the fearsome Corinthian.
