DEZMYR & ZALTHAR SHADOWDUSK
The current leaders of Shadowdusk Hold are the twins Dezmyr and Zalthar Shadowdusk. These former paladins of Torm abandoned their faith long ago, becoming death knights. They have remained close throughout life and undeath, and might have led their mortal family skillfully if circumstances had played out differently.
The twins are devoted to each other and are obsessed with returning their family to prominence and ultimately seizing control of Waterdeep.
