The Slayer's Guide to Duergar
This roleplaying supplement explores duergar, or grey dwarves, who inhabit the cold depths of the Underdark and compete with other subterranean races for dominance. It details their physiology, society, dark religions, habitats, and roleplaying traits, including guidance for using duergar as player characters. Additional sections examine duergar warfare in lightless environments and present Verhaven, an intricate militaristic duergar community. Their cunning, discipline, and capacity for treachery are examined as sources of danger and conflict in underground adventures.
