A Watchful Eye
The Great Contagion is a plague which struck Creation at the end of the First Age of Man; the plague was so virulent that it killed 90% of the infected population. A great plague unleashed on Creation by the Deathlords during the waning days of the Shogunate. Wiping out nearly all human life, it weakened the defenses of Creation, prompting the Fair Folk to invade. This led to the heroism and triumph of the Scarlet Empress. The Contagion was engineered by the Deathlords, particularly the Dowager of the Irreverent Vulgate in Unrent Veils.
