The Fall of Camelough came at a time of great turmoil on Oerth and in the Heavens. After the Silver Towers crumbled to the earth, the Thirteen Mages set out to seal the Dark One's Palace, entombing the evil wizard for eternity within his own Palace. However, the Dark One lashed out as the mages formed their magicks, and the madness of the Dark One's Curse caused the tomb to be flawed, allowing it to weaken over time until the Dark One was able to affect the world again.

The Dark One's Curse triggered a great disruption on Oerth, causing mages to go insane and wreak great havoc. Cities were destroyed, and in some places, the flows of magick were permanently disrupted, leading to locales where Heka no longer flows. In other lands, great tracts of land broke free of the Oerth, floating into the skies to form the Floating Islands of Lantea.

But this was not the only place where great turmoils were unleashed. Astronomers noted in the days after the sealing of the Dark One's Palace that the Morning Star had become significantly brighter. Some Kelltic astronomers believed that it was a response to the Fall of Camelough, while al-Rhayidhian sages believed it related to the sealing of the Palace or the Dark One's Curse. As it turns out, they were both wrong, for the stars had aligned not only on Oerth, but on other worlds as well.

The Cosmology section is divided into two sections. The first section, the Players' Section, contains information known to inhabitants of Oerth. While not every persona will know all of this information, it is something a sage with expertise in astronomy will know.

The second section, the Journey Master's Section, contains a lot more detail about the solar system, with a lot of information that should be considered spoiler info. Players may read it, but there is no way for their personae to know any of the information contained in the JM's Section. The JM's Section also contains more precise data about the planets.
