Oh, nevermind. I just noticed that the initial Diplomacy check counts for the group.
Madam eva will flip another card: The Devil.
"That creature is a cause of death, death which walks the street of Barovia. Death leads to death, all stemming from a first death."
She then flips another card, covering The Devil.
"You must an end to the blasphemy of the death that refused to die, but that will not stop the plague. The lord of the castle is the source of it all. The cards speak of a powerful creature, anathema to life, which is created from the corpse of a relative... Whatever it is, Strahd had a hand in this!"
She flips a second card, crossing the first two with it.
"To end the plague of death, you must end its source. The village church is desecrated by the first blasphemy. The castle is ruled by the greater one. Yes, it is exactly as I thought..."
Creature in the church.
