My group is gearing up to face Strahd this evening. Anything I should keep in mind?

CoS Spoiler – Is the vestige that broke free in the Amber Temple a nod to something at all?

Anyone have ideas on how to run Arabelle as an ally in Curse of Strahd?

At which point/how often would you have Strahd appear to PCs?

What’s the best way to introduce new PCs in Curse of Strahd?

Can I resurrect Strahd?
