part of Oerik, the Flanaess. At that time, far to the west of the Flanaess, two peoples were at war, the Bakluni and the Suloise. The war reached its climax when both sides used powerful magic to obliterate each other, in an event called the Twin Cataclysms. Refugees of these disasters were forced out of their lands, and the Suloise invaded the Flanaess, forcing the Flannae to flee to the outer edges of the continent. Several centuries later, a new invader appeared, the Oeridians, and they in turn forced the Suloise southward. One tribe of the Oeridians, the Aerdi, began to set up an empire. Several centuries later, the Aerdi's Great Kingdom ruled most of the Flanaess. The Aerdi overkings marked the beginning of what they believed would be perpetual peace with Year 1 of a new calendar, the Common Year (CY) Reckoning. However, several centuries later, the Empire became decadent, with their rulers losing their sanity, turning to evil, and enslaving their people. When the overking Ivid V came to the throne, the oppressed peoples rebelled. It was at this point, in the year 576 CY, that Gygax set the world of Greyhawk. As Gygax wrote in his World of Greyhawk folio, "The current state of affairs in the Flanaess is confused indeed. Humankind is fragmented into isolationist realms, indifferent nations, evil lands, and states striving for good." Gygax did not issue monthly or yearly updates to the state of affairs as presented in the folio since he saw 576CY as a common starting point for every home campaign; because each would be moving forward at its own pace, there would be no practical way to issue updates that would be relevant to every Dungeon Master. Gygax was also aware that different players would be using his world for different reasons. When he was the Dungeon Master of his home campaign, he found that his players were more interested in dungeon-delving than politics; but when he switched roles and became a player, often going one-on-one with Rob Kuntz as Dungeon Master, Gygax immersed his own characters in politics and large-scale battles. Knowing that there would be some players looking for a town in which to base their campaign, and others interested in politics or warfare, Gygax tried to include as much detail as possible about each region, including a short description of the region and its people, the title
