The main character of "The Sandman" is Dream, also known as Morpheus and other names, who is one of the seven Endless. The other Endless are Destiny, Death, Desire, Despair, Delirium (formerly Delight), and Destruction (also known as 'The Prodigal'). The series is famous for Gaiman's trademark use of anthropomorphic personification of various metaphysical entities, while also blending mythology and history in its horror setting within the DC Universe. "The Sandman" is a story about stories and how Morpheus, the Lord of Dreams, is captured and subsequently learns that sometimes change is inevitable. "The Sandman" was Vertigo's flagship title, and is available as a series of ten trade paperbacks, a recolored five-volume "Absolute" hardcover edition with slipcase, a three-volume omnibus edition, in a black-and-white "Annotated" edition, and is available for digital download.
