Im changing the Feast of St. Andral

The sky will look stormy but just as rain starts, the storm clouds dissipate like a miracle(Strahd disguised as Vasili's magic).  lf the players have not found the bones of St. Andral and the vampire spawn in the coffin maker's shop, then the spawn are the festival minstrals.  When the wicker sun is lit it becomes a proper festival for a while.  If the spawn minstrals are still alive and havent been found out, then they start playing, maybe getting some townsfolk or players to dance onstage with them.  lf the spawn are dead then Ireena and Vasili are the performers, and the threat is Fiona Wachter's cult.  Once the players are either distracted or surrounded, the attack starts.

What do you folks think?
