Shadow of the Cacklefiend
Nifas was the second largest Haksoon city built during the time of their empire and it fell like the rest of their Empire during the Cataclysm. Like most other Haksoon ruins it is avoided by all but the most desperate, foolhardy or stupid.
In recent times it has been reported that the ruins of Nifas have become resident to some giant creature that moves through the sands and destroys entire caravans that draw to close to its layer. No one knows what this creature might be, but the Imer, Elves and Niyyat gnolls all fear it. These desert tribes know all the creatures of the desert intimately, but claim the Nifas-Horror is unrelated to any of them.
The only clue to its identity is the fact that Blight Dragons have been seen in frightening numbers in the area. Perhaps the ancient ruin has become home to one of the last true Dragons of Eden. If so, no living creature is safe anywhere near the ancient city.
