Regardless of what you think of the idea, the developers have made it very clear that the GC and his children are relevent, so the suggestion that they shouldn't be so important really doesn't do anything to advance the discussion of just what was intended for the setting canon.The Dark One wrote:At all, this Gentleman Caller + family focused demiplane issues are starting to make me sick.... an entire setting depending on one being and his children.... doesn't make sense (for me).
As well, why can't one being or family be integral to events in Ravenloft? After all the realm itself (in both its historical and real-world contexts) was created around one person, Strahd.
