Vath
Drow Dragonlord
Vath is a drow Dragonlord who rules through coercion. He enslaves the dwarves of Dwarfhold, withholds food when their work disappoints him, and uses a sword and amulet to command Stalagbite as a weapon. Even when the dragon is exhausted, Vath demands that he keep fighting. Once freed, Stalagbite carries him away despite his protests. In the distant past visited by the Hero, a King Vath instead protects the dwarves and says he sent Stalagbite and the Rock Roc to evacuate them.
