Dragon Break

A Dragon Break is a phenomenon where linear time is broken, and becomes non-linear. The "Dragon" refers to Akatosh, the Dragon God of Time.
A Dragon Break not only precedes significant changes in Calradia, but challenges mortal comprehension. It is a re-alignment of time and space in response to an event which makes the normal continuity of reality impossible.
The area that is noticeably affected, and length of the interval measured in the areas not apparently affected, varies with each Dragon Break. Historically, the cause is often attributed to mortals manipulating divine matters.
