From the Dracula Dossier Kickstarter Campaign In PERVENIET CALIX, the main cast are the Dukes of Edom, tasked with the impossible -- harness a medieval vampire for the 21st century's shadow wars. Now rogue agents -- and your fellow Dukes -- are making the impossible even worse. This DramaSystem Series Pitch can be played as a standalone game, or in between sessions of your Dracula Dossier campaign, setting your Night's Black Agents player-character heroes as the GM's screw-tighteners par excellence.
