The Emberverse series—or Change World—is a series of post-apocalyptic alternate history novels written by S. M. Stirling. The novels depict the events following a mysterious—yet sudden—worldwide event called "The Change" that occurs at 6:15 p.m. Pacific Standard Time, March 17, 1998. The Change alters both the course of history and all physical laws when it causes all the electricity, firearms, explosives, internal combustion engines, steam power and most forms of high-energy-density technology on Earth to permanently no longer work. Most of the action in the series takes place in the Willamette Valley of Oregon in the United States. The series primarily focuses on how the characters survive the loss of 600 years of technological progress. The first book, Dies the Fire, concerns the conflicts between a Portland-based neo-feudalist dictatorship and the free communities of the Willamette Valley, primarily the Bearkillers and the Wiccan Clan Mackenzie. The later series, The Change, focuses on the now-adult children of the original trilogy's major characters. A third sub-series, beginning with The Golden Princess, features the grandchildren of the original survivors as the central characters, and concluded with 2018's The Sky-blue Wolves. The Emberverse is closely related to the preceding Stirling Nantucket series. Both deal with the aftermath of The Change, though its effect is radically different in the two series. Novels and short stories Novels Short stories Most of the short stories so far are set 50 years after the Change, except for "Pronouncing Doom," which is set in 1999. Some in the Collection The Change: Tales of Downfall and Rebirth are set throughout the Emberverse series. Other media At the 2009 DragonCon, Stirling said Sony has expressed interest in a television series based on Dies the Fire, with each season being one year. His agent was also discussing a Dies the Fire webcomic that would eventually be published as a graphic novel. Post-Change Oregon Though the Change caused a large loss of life everywhere, Oregon suffered less than most places of similar population density. Although the region lost over 95 percent of its population, it was spared being turned into a "death zone" with no survivors except bands of cannibals—the usual fate for areas around large cities—for several reasons. First, much of the population of Portland—the largest city in the region—was forced out by the Portland Protective Association (PPA) and either died en masse or joined the tens of thousands congregated in large
