For the most part, even darklords don't realize they are darklords. With a few exceptions like Azalin, Vecna, Lord Soth and Strahd, most of the evils of Ravenloft will believe themselves cursed, with no concept of the Dark Powers.<br/><br/>Characters could certainly believe there's a malevolent architect handing down misery from on high in Ravenloft, and it's definitely reasonable to call it something like Dark Powers, but they would never receive any confirmation of that belief. If the Dark Powers start whispering to you directly, you're in way too deep to ever come back.
