While most dwarves moved to Golarion’s surface as part of the Quest for Sky, some doubted their god Torag’s warnings and remained behind, only to be driven further underground by the prophesied calamities awaiting those who didn’t leave their homelands in Nar-Voth. Facing defeat at the hands of other powerful forces in the Darklands, these holdouts accepted an offer of help from the outcast dwarven god Droskar, the Dark Smith. He helped them reclaim their former glory, and in return they bound themselves and their descendants into his service. As a reminder of their bargain, he turned their skin gray, after which they became known as the duergar. The duergar see themselves as the only true dwarves and seek to retake all their former holdings underground, coming to the surface only to kill their cowardly cousins and capture more slaves for the endless work of repaying their debt to Droskar.
Escalations, How Do They Work?
The River Kingdoms are home to a variety of monsters and predators, most having few plans beyond their next victim/meal. However, larger threats regularly pop up in the Monster Hexes, filling them with their own forces and expanding to neighboring hexes unless players work together to take them down. These are called Escalations, and when left alone they tend to grow in strength and size, spawning more and more creatures, as well as more powerful ones, to fill the growing number of hexes they control.
