In the World of Greyhawk campaign setting for the Dungeons & Dragons roleplaying game, Keoland, properly known as the Kingdom of Keoland, is one of the oldest political states in the Flanaess.
Keoland was founded -342 CY (303 OR via a union of the Suel houses of Rhola and Neheli, and minor Oeridian nobles which had also settled in the Sheldomar Valley.
Bordered by the Javan River to the west, the Azure Sea to the south, the Sheldomar River to the east, and the Rushmoors to the north, Keoland is the largest nation in the Sheldomar Valley. The climate is normally temperate year-round.
As of 591 CY, the population of Keoland totaled 1,800,000 persons, the vast majority being humans of chiefly Suel and Oeridian stock. Elves, gnomes, halflings, and dwarves, make up perhaps 20% of the total population.
The most popular deities among the Keoish are Heironeous, Phaulkon, Saint Cuthbert, Fharlanghn, Ehlonna, Lydia, Osprem, Zilchus, Kord, Xerbo, Norebo, Olidammara, the Seldarine, and Trithereon.
