Gradsul is the most populous (49,400) city in all of Keoland. It is a base of operations for both sea-borne and urban adventures. The “Haven of the Suel” is an ancient city ruled by House Rhola and sits at the mouth of the mighty Sheldomar River on the western Azure Sea.

First detailed in Living Greyhawk Journal #1, there is a lot going on in Gradsul. The city is mercantile, cosmopolitan and well defended; it's focus was once on exploring the south seas and jungles. The threat of the Scarlet Brotherhood keeps Gradsul's navy on alert. Gradsul is friendly to free-wizards (unlike the rest of Keoland) with a guild of Sea Mages supported by the legendary arch-mage Drawmij. There is also plenty of thievely work to be done in this wealthy city, or maybe you have a fighter who'd like to join the Knights of the Watch whom are found in great numbers.

As a base of operations, Gradsul is centrally located for adventures striking out in all directions such as east across the high seas, to the west within the ominous Dreadwood, south to the Hool Marshes or farther inland where courtly intrigue and knightly quests await.
