Burgomaster's house
Burnt to a crisp
Was “accidentally” burned down by the players. They set it on fire in order to make a large enough distraction to get Rictavio out of Vallaki with his tiger. The house failed its death saves and burned to the ground. A shiny something was spotted in the rubble.
In the rubble of the house, the party found: a magic mirror, a leather-bound book belonging to Strahd, the charred remains of dozens of dolls that resemble Ireena, a door that had been whacked by lightning, a skeleton in shackles and the bones of a large dog
