Title: Destiny: A Chronicle of Deaths Foretold
Content:  Destiny: A Chronicle of Deaths Foretold is a 1996 comic book mini-series published by Vertigo, written by Alisa Kwitney and with art by Kent Williams, Michael Zulli, Scott Hampton and Rebecca Guay. A spin-off from Neil Gaiman's Sandman series, it features Destiny of the Endless, a character available for use by other writers because, unlike the other Endless, Gaiman had not created him. Published in prestige format, each of the three issues detailed a story of a different plague from history, with a framing sequence set in a future world decimated by a new plague. Each issue's story was illustrated by a different artist, with Zulli, Hampton and Guay painting issues one, two and three respectively; the framing story and cover art were by Williams. The title is a reference to the novel Chronicle of a Death Foretold by Gabriel García Márquez.
