Few goblins were allowed to survive as slave stock within the Dominion, these base creatures were often despised as filthy and useless. Those who were not simply destroyed at birth (many more goblins were born each year than could be put to use, even in slavery) were given some of the more unpleasant jobs of society: maintaining midden heaps, mucking out stables, cleaning the sewers of the larger cities, and so on.
After The Collapse, most goblins came to live in and under the ruins at the heart of the Domion, surrounding the former capital. As these lands have slowly sunk into surrounding sea, forming a brackish swampland, these creatures have become more and more at home. They provide a serious threat to individuals seeking to investigate or loot these ruins for their fabled, lost treasures.
