Pact of Greyhawk
This pact led to a formal cessation of hostilities between Iuz, Furyondy/Veluna, Keoland and allies, Nyrond and Urnst, the Scarlet Brotherhood, and a representative of Ivid the Overking. Those not included were the humanoids of Pomarj and Bone March, Ratik, the barbarians, other Aerdi rulers, and the exiled leaders of vanquished lands.
The global political picture regarding accepted boundaries is reflected in the world map, of course. Free trade was permitted, in theory, between states and nations, but distrust has minimized it. Of course, certain powers wrung their hands at their inability to control the enthusiasm of certain rebel mercenaries, humanoids, or partisans within their lands. These powers expressed their deep regrets at not being able to wholly prevent skirmishes from within their lands (Iuz’s representative feigned especial regret at this), so peace is not exactly complete.
As far as the Free City is concerned, the major change produced by the Pact is that permanent ambassadors of the major signatories are now resident in the Free City. In theory, this is to allow any breaches of the Pact to be discussed by these representatives on short notice; this stipulation in the Pact was at the insistence of the Scarlet Brotherhood, masters of intrigue and espionage. Nerof, of course, added the fine print that ensured payment for the privilege of keeping an ambassador in the city.
