The Tyrian continent is the location where most of the Prophecies Campaign took place. The earliest known intelligent life began on Tyria 3000 years ago, though there are signs of creatures estimated to be from roughly ten thousand years ago. It is also known that the Gods of Tyria used to live in Tyria (in the present-day ruins of Orr) for some time prior to the Exodus. The official calendar in Tyria is the Mouvelian Calendar. Tyrians use writing systems that differ from known languages, and thus the actual signs on roads cannot be read (thankfully, the user's language is used to help with directions).
