The Fair Folk are an infrequent and yet persistent problem in the Hundred Kingdoms, scattered here and there about the land, both hidden in secretive freeholds and lurking in the occasional bubble of the Wyld. Some keep largely to their own devices, others trade regularly with the guild for Slaves, and a few even engage in scattered bits of raiding (not seeking to draw down too much attention). The most dangerous threat, however, is running across a stray Noble and his entourage out for a bit of sport.
The greatest concentration of Fair Folk in the region are centered on the fallen ruins of Madadhine. Once a great city of the First Age, that even managed to weather the Great Contagion to some degree, the city fell before the remorseless onslaught of the Fair Folk as they rampaged through the city. Even today the touch of the Wyld remains strong, and the area around the ruins are a no mans land for some good distance. A fair sized gathering of the Faerie lurks within the chaos of the Ruins, only occasionally emerging to raid their surroundings for fresh souls. Their presence, by far, keeps the surrounding states weak and fragile -- but also drive away most would-be conquerors.
The Guild maintains contact with two Freeholds, one somewhere far to the North near the borders of the Hundred Kingdoms with the Linowan and the other rumored to exist somewhere within a few weeks travel of the Nulam itself (hidden, the rumors say, under a Hill). The flow of slaves into these locations is steady, and provides the Guild with both gossamer and the soulless husks of the "leftovers". This trade is exceedingly unpopular however, and the Guild does its best not to advertise it.
