“The northward-thrusting arm of the Abbor-Alz is known as the Cairn Hills. These hills surround Midbay on Nyr Dyv and form the borderland between the territory claimed by Greyhawk City and that of the Duchy of Urnst. Several thousand gnomes dwell in the central position of the Cairn Hills, halflings enjoy its lower Northern slopes, while many dwarvenfolk live in the area where it meets the Abbor-Alz and the hills have become young mountains. In the hinterland below Nyr Dyv's Midbay, where the hills are very rugged, there have been strange burial sites discovered from time to time. These rich finds are of a people even unknown to the demi-humans, evidently predating them! Discoverers returned with harrowing tales of horrid guardians, death, and worse, but carried back ingots of precious metals, gems and other treasures as well. The discovery of these burial sites gave the hills their name, and also makes them a target for many foolhardy adventurers. There are no settlements east of the marshes around the Upper and Lower Neen Rivers until the eastern edges of the hills are reached.” Gygax 1983
