Here's my take on what Barovia may look like after the Time of Unparalleled Darkness. Let me know what you think!
BAROVIA
Simple Substitution – There's a lot to choose from here. Candidates include Lyssa von Zarovich, Inajira, Leo Dilisnya, Ardonk Szerieza ... heck, even Sherif von Zarovich could fit the bill if you wanted to include that screwball.
Evil Evolved – But if you want to have your cake and eat it too you could just give this domain the ol' Necropolis treatment. That's right...instead of Azalin it's time to set Strahd free! Maybe one of those infamous heroic expeditions to Castle Ravenloft actually succeed in killing the vampire lord. Or Strahd finally managed to capture the heart of Tatyanna's reincarnation and seen the error of his past actions.
Either way, he's out of the picture. You might think that now that the devil Strahd is no more, the life of Barovia's inhabitants would improve and that maybe hey can finally start to embrace the progress that the rest of the Western Core has enjoyed for so many years.
But just the opposite happens. Without Strahd's strong hand all the monsters of the night become bolder and various factions around the domain take advantage of the power vacuum. Inajira lords over Teudeldorf in the guise of a powerful warlock. Ardonk Szerieza turns away from Invida and begin a successful campaign to reclaim the former Gundarak lands. Leo Dilisnya is set free from his centuries long curse and runs rampant throughout the countryside of Krezk. Lyssa von Zarovich either exercises her power from Zeidenburg or takes up residence in Castle Ravenloft as the heir to the throne. Even Sheriff von Zarovich carves out a little kingdom for himself somewhere out of the middle of the domain.
Basically, Barovia becomes Balkanized, a fitting fate for a domain based on the historical Transylvania . To the regular inhabitants the situation is just as bad as when the Tergs invaded all those centuries ago and there are some people who think the problem would be solved by bringing back a true Zarovich to the throne...
Extreme Makeover Edition – To build off that scenario even further, let's say that Jandar Sunstar hears of the turmoil that Barovia is now going through and decides to return and try to set things right now that Strahd is gone. But is he too late?
At first, he is seen as an avatar of the Morning Lord and the people rally behind him. Hope is finally returned to the land! Instead of vampires preying upon the peasantry there are trained monster hunters that go and battle the creatures of the night. I'm picturing a situation similar to the movie
Stakeland, where there are large areas that are considered “vamped” with small settlements being packed with refugees from the countryside.
Despite Jandar's best efforts, however, the vampire menace keeps growing. It's almost as if the cursed soil of the land is creating more and more of them. So, Jandar has to institute harsher and harsher protocols to protect the few remaining human enclaves before they are overrun completely. Now, the man that was once hailed as a hero eventually turns into something just as bad as Strahd was...
