Any tips on where to take my PCs once I’ve finished Started Set adventure?

One of my players encountered a ghost and aged 30 years!

Are prayers intercepted/granted by Strahd/Dark Powers?

How would you handle PCs that always cast Light?

Would you still say that a unicorn is appropriate for wild magic in Barovia?

Too much “Blah!” or “Boo!” can ruin the suspense!

I killed a raven in my Strahd play through should there be any punishment?
