Dies Ignis is an apocalyptic document written in Latin, supposedly by Lucifer himself. It details the history of the world in four sections, from its beginnings to its apocalyptic end. A fifth section tells of three possible routes for humanity to escape the coming Time of Judgment. It is also known as the "Oxford Text".
There is some argument as to which text came first: the Latin Dies Ignis or the Greek Imeres Pyros. While both texts repeat largely the same information in roughly the same manner, it seems that if one was to read both texts, they mesh together and tell a more complete story. Among those who came to understand the fullness of both texts were John the Baptist and FBI (SAD) investigator Woodrow Miller.
The original Dies Ignis text was stolen from its safe. Left in its place were two papers: one featuring a "poem" made up of 26 individual lines taken from various places within Yves Darra's Days of Fire, and the other featuring three newspaper clippings: one regarding a new, slightly faster speed of light; one about a supposed new celestial object; and one regarding the disappearance of a museum curator.
Oddly enough, the "poem" spelled out the name Woodrow Miller twice, leading Agent Miller to believe that the perpetrator knew that he'd get assigned to the case due to his particular expertise.
The original text was never recovered.
