In the Firefight prologue, Calamity rises and then, "the screaming began." Why would people be screaming? Wasn't there only epics a year after Calamity? And somewhere in Calamity (book) it is stated that "strange occurences" happened after Calamity.
So what happened? I thought maybe there was earthquakes, or warping in space, or some other cataclysmic event.
