Most of this timeline was revealed in the official artbook, , as well as a few events unmentioned in-game. The rest are based on comments from Dishonored: The Dunwall Archives Dishonored's co-creative director, Harvey Smith.
The Great Burning which led to the beginning of the modern calendar is described as a time dominated by cultural destruction – the period was effectuated by a roving cult which grew to enormous size and visited ruin upon all cities. This suggests that the Great Burning was an event orchestrated by human hands and not something linked to the supernatural.
