Post Greyhawk Wars: 585 CY
These hills have been overrun by the humanoids of the Bone March. The few demihumans who lived here were forced to retreat to the Flinty Hills. Along their eastern flank, the Tessar Torrents are an effective boundary from the North Province. These hills are notoriously hazardous for travel, with many sinkholes and slopes of crumbling rock, and the unmaintained mines of the demihumans periodially cave in and create further danger.
