"Leda! Please don't quarrel with our friend. You are allowing the archfiend his way when you do that," Gord said gently. "His question was deserved. It was also practical." The three had been chivvied and chased across the whole of the world. From the distant south, through the Moving islands, up and across Gonduria's vast continent, and thence across the Agitoric Ocean to western Oerik's shore. No fastness or barren or mountain chain had served to conceal them from the hounding of Tharizdun and his yeth.
-- Gary Gygax, Dance of Demons, p. 402The location of the continent of Gonduria and the Agitoric Ocean has been a question that has vexed Oerthophiles for quite some time. We are told in the Guide to the World of Greyhawk Fantasy Setting that "Oerth has four great continents and countless islands, and four great oceans and countless seas which surround these bodies of land." (Guide, p. 4) But the Guide only names one of them; Oerik, the continent on which the Flanaess can be found. The text accompanying the Dragon Annual #1 map clearly refers to Hyperborea (the icebound land at the north pole of the planet) as a continent. So that's two down.
The names (if not the locations) of the oceans are all accounted for. The Solnor and Dramij Oceans appear in the original folio maps. The Ocean of Storms and the Oceanum Titanicum are in the DA#1 map. And finally the Agitoric Ocean is mentioned above, but there's no indication of its location except that it is between Gonduria and the western shore of Oerik. Hey... wait a sec... that's five oceans! Obviously two of those named above are actually different names for the same body of water. But which two? Back to that question below.
We are also told that Aquaria is one of the continents on Oerth, some 5,000 miles east of the Flanaess across the Solnor Ocean (which, we are told is only 3,000 miles wide!). Some sources state that Aquaria is on Aerth rather than Oerth, but there's no reason there can't be an Aquaria on both; the one on Aerth is 5,000 miles away, the one on Oerth is only 3,000 miles. Works for me. So that's four continents named. But where the heck is "vast" Gonduria?
For a while, I was inclined to label the westernmost portion of the vast landmass found in the DA#1 map as Gonduria. In the same way that Asia and Europe are deemed to be separate continents even though they share an enormous land border, so too it made sense to me that Gonduria and Oerik could be situated. That would put "the western shore of Oerik" as the western coast of the peninsula upon which the Nippon Dominion is found and would fit in nicely with the quote from Dance of Demons, above.
We also know that François Marcela-Froideval's campaign, which includes the lands of Lynn (Lhynn), Erypt, etc. fills up the southwestern portion of Oerik. His Chroniques de la Lune Noire have a ton of information on this region, but that's a subject for another post...
That landmass, I think, fills the bill for Gonduria. It's in the right place (assuming the waterway between it and Oerik is in fact the Agitoric Ocean; we're still working on that superfluous fifth ocean). Is it "vast"? Well, it's about the same size as the Flanaess, so given the fact that "vast" isn't the most precise unit of measurement ever invented, I'd say it could apply. It's certainly in what would be called "the distant south" from a Flanaess-centric point of view. And, given its position, that would cinch the identification of the Agitoric Ocean as being one in the same as the Oceanum Titanicum. From our postulated Gonduria you cross it to get to the western shore of Oerik. Nice and neat, methinks.
Aquaria, home of the Aqua-Oerdians and Frank Mentzer's campaign since 1976 or so. Time for an itsty bitsy bit of math. (I know, I know, I'm ignoring the implications of a spherical world and Mercator projections and that stuff. I'm a history major, not a geography major.)
Oerth has a circumference of 25,200 miles. Oerik is (very) roughly 10,000 miles across, including the Flanaess. The inset map from the Living Greyhawk Gazeteer is about 21,500 miles across from edge to edge. Coincidentally, from the eastern edge of the Flanaess on the LGG inset map is... 3,000 miles. Just the right amount of distance to cover the known width of the Solnor ocean before it hits the edge of the map. And that map also leaves us with roughly 3,700 miles to have another continent which would be... Aquaria. Not that Aquaria has to be 3,700 miles across; it could be significantly smaller. But it would be continent-sized, and therefore would serve to separate the Solnor Ocean from the Oceanum Titanicum/Agitoric Ocean.
So there it is. Gonduria is the continent southwest of Oerik. The Agitoric Ocean is the same as the Oceanum Titanicum, and is separated from the Solnor Ocean by Aquaria. Four continents, four oceans, lots of disparate canon sources, some of which are mutually exclusive, reconciled. Ta-da! If you put the pieces together, it looks something like this:
(Note that Aquaria is on there just to establish its position, not to indicate its actual shape. Continents and oceans are capitalized.)
I realize some of the above conclusions diverge from those of other Oerthophiles, some of whom name Hepmonaland as a continent, and who conflate the Agitoric Ocean with the Ocean of Storms, along with other differences. But given the sources, I think my solutions make a lot of sense, and of course since it's all "canon reconciliation" there is no single right answer. If I've overlooked anything, I'm sure my gentle readers will let me know.
