Here's the stand I'll take.
After the Sturmkirks, Volkimir's family, become vampires, the lands which they owned became a barbaric monstrosity, filled with all manner of craziness and shadow. Over time, the Stormlands become known as the Shadowlands. In the centuries preceding the events of the roleplay, the various states of Ansus unite to form the United Kingdoms of Ansus, which eventually rise against the Shadowlands and destroy its influence in the Horror Wars. All this occurs in the 2000 years before the events of the roleplay. The United Kingdoms of Ansus change their name to simply Ansus, with the longer name 'Federation of Ansus.' This happens after the lives of Crow, Ki'ira, Jacaerys, and Altim, who live in an era when piracy is dying and countries start to unify, much like Cynderia.
Before that, a cataclysmic war happens around 29000 PA and ends around 30000 PA. This war is called the Great Hundred Years War, and it is a war waged initially between 5 or 6 separate empires. Unrest after the war leads to balkanization, and the countries are thus split into anywhere from 30 to 100 warring, sometimes feudal states, with surrounding minor kingdoms and provinces. Daen lives towards the end of the Great Hundred Years War. Balor lives before the conflict.
Clarent, Jaralia, and Zhan's lives all precede the Horror Wars, and these three characters may not have anything immediate to do with each other. But they probably had some effect on history relevant to the time periods they lived in.
The rest lived in the time period before the Great Hundred Years war, and they lived closer in proximity to each other. We could probably write a history relevant to and connecting them too.
Is everyone game?
