In the years since, the original has gained a reputation as one of the greatest Dungeons & Dragons adventures ever, and it went on to inspire the creation of a campaign setting of the same name in 1990: Ravenloft, home of the Domains of Dread.

The base scenario is Forgotten Realms 5th edition, after spellplague.
