Millennium

This black stone castle has stood for just under half the duration of the thousand-year rule the first overking proclaimed as his empire's fate. Millennium withstood a siege by Szeffrin's forces for three months during the final phase of the wars, and the Pact of Greyhawk allowed the Nyrondese survivors—only 300 of the 1,500 who were originally garrisoned here—to depart in safety, Nyrond being forced to give up the lands around the castle.

Millennium stands above a warren of sea caves and caverns, further excavated over the centuries. The fiends which have taken up residence in the castle (and the Nyrondese have seen greater tanar'ri here) have begun the task of filling those catacombs with an undead army from the bodies of those who fell defending the castle. Disease-ridden corpses are floated down the shoreline into Mithat Bay in the hope of infecting Nyrondese folk, though most bodies are kept for animation.

Millennium is primarily garrisoned by orcish troops, with fiend commanders; there are few humans here. Because the departing Nyrondese were searched by Szeffrin's gloating servitors, some treasures and precious items had to be left behind when the castle was evacuated. The orc warlords here also use this castle to stash their war booty, so there is fair treasure to be had for anyone prepared to face the defenders of this redoubt able castle.

Towering over a rocky clifftop at Seawolf Point, this black stone castle withstood nearly three months of siege when cut off from Nyrond's armies during the wars. Originally built by the Overking in 107 CY, the castle was named for the thousand years the Aerdi overlord believed his great kingdom would endure.

The terms of the Pact of Greyhawk allowed the survivors of the siege, but a fifth of the 1,500 souls originally garrisoned there, to return to the kingdom. Gleeful fiends took up residence in the castle, and the extensive catacombs below.

The rocky cliff face below the castle has many sea caves and shafts bored down into them over many centuries. The fiends and priests here are said to have begun the task of filling the catacombs with undead from the corpses of those who fell defending the castle.

Disease-ridden bodies are deliberately floated along the shoreline into Mithat Bay from here in the hope of infecting the Nyrondese. The garrison of Blazebane protects the approaches to the bay with wide nets to catch the briny, bloated corpses.
