The Hidden represent denizens of the Underdark. The most famous are the Dark Elves and Drugar cousins to the Sylvan and Stouted, respectively. Creatures of the underdark live lives of stealth to survive in the harsh underground environment, and are weakened by sunlight but empowered by darkness. Their societies and kingdoms are complicated in their laws and alien in their customs compared to the surface kingdoms, but like the people of the surface, they have no overarching moral inclination. While many underdark cultures shun the surface entirely there are many who trade openly with them. The Hidden societies play an important role in maintaining the ecology of the subterranean world, these groups ensure that the dangers lurking underground remain contained. Creatures born of one of the most hostile environments known are a hardy and resourceful lot which should never be underestimated.
