We had another positive session yesterday. I was all set to have the monkey performing in the street to draw them to Blinsky's, but the first thing they did after leaving Madam Eva's was head back up to Luvash and Arrabelle to ask after the prophecies, and they pointed them to Blinsky. Then they had the meeting with Strahd; I took Wepwawet's advice and had my charmed character reveal to Strahd (after the other characters refused to tell him) where Ireena was, and that got the story moved along pretty quickly. They ran into Rictavio heading to the tower as they were headed back to Vallaki, and I decided that their meeting Madam Eva and getting a visit from Strahd made them interesting enough to Rictavio that he told them where he was headed.
In Vallaki they made a beeline for Blinsky's (after stopping for a short rest in the Inn, since my character was at 2hp after being bitten by Strahd and the subsequent fight with the wolves). They tried really hard to buy the Ireena doll, really taxing my ability to roleplay a fairly thin character and maintain his accent. They're very reticent to tell anybody directly about the card reading results, so it took a while for them to figure out that Madam Eva was talking about Rictavio, not Blinsky, as their ally, but they got there. As they left, they met Ismark coming up from the Burgomaster's looking for them, Izek having kidnapped Ireena that afternoon. Together then they put together that Ireena and Izek were probably related, and headed to the mansion. Izek gave them more room for the PCs to talk to him and convince him than maybe made sense for his character, but that was the resolution I really wanted. We pointed out that Strahd knew Ireena was there, and the seven of us (party plus Ireena, Ismark, and Izek, who's going to protect Ireena forever now) headed for the tower. The Burgomaster tried to stop us, but Izek stood up to him, and they both knew the guards couldn't stop Izek; the Burgomaster hollered a "I'll have your heads for this" as we left the mansion, which got called out for being Scooby Doo-ish.
When they reached the tower they set off the lightning trap one time, then after it subsided Rictavio hollered out some help from the window. They still set off the blue dragon, but quickly got the door open to dismiss it. I probably should have played that slightly differently, going into rounds as soon as the dragon appeared. I kind of panicked though; the only thing I could imagine the dragon doing was breathe lightning, which would have been devastating, and I'm very gunshy about killing off my party. So while I was trying to work that out they got the door open, so I just let it be. They all got to the top of the tower, talked with Rictavio, and after they convinced him he's their ally he removed his hat and introduced himself. They talked about some of the other card readings, which got Krezk into their vocabulary (he suggested it could be the "fortress," and it's one of the only places outside Ravenloft that might have legitimate crypts). Then, as it was just about dark, Ezmerelda showed up. Just as she got upstairs, we heard werewolf howls from outside, and I called it a night because I wasn't prepared to handle either of those things yet.
So now we have NINE people in the tower, and I don't know where the party is going to want to go next. The druid is out of spells and my character is stuck at half health after the Strahd bite, plus Ezmerelda is jacked up, so we're highly motivated to stay the night for a long rest in the tower. I'm not sure if the werewolves will allow that. And I don't know where they will choose to go next. Krezk seems like a possible safe destination for Ireena &c, and I'd be happy to get them to do the Wizard of Wines quest (which they've heard once from Urwin). The other places they've been pointed toward are the Castle (crypts) and the Amber Temple. I don't think they have any more interest in Vallaki. They're very focused now on the card reading information. Ezmerelda can probably both give them information about the Castle and discourage them going there yet. I don't know whether I should nudge them toward destinations, or try to be prepared for every possibility.
What should I do about Vallaki now? Assuming they don't pass through in the next couple days, there's a lot going on there without them. The Festival doesn't really matter, but Strahd is still set to attack the Church, and now he thinks Ireena is there as well. The Burgomaster's power has been neutered with Izek out of the picture. I didn't introduce Wachterhaus and the associated politics, but I could still have Lady Wachter usurp the Baron's power while the party is away, probably after Strahd attacks. Basically, is Vallaki going to be in ruins, either physically or functionally, the next time they visit? What makes the best story for the PCs going forward?
