Realm of Terror (1990). This book outlined that the size of Ravenloft is "40,000 square miles [spanning] 26 different domains, including Barovia and Mordent. All of the core domains are overviewed in Ravenloft, as are eight 'islands'." The revised 2nd Edition boxset Ravenloft Campaign Setting (1994) is an update to Realm of Terror, however, it removes Domains that were destroyed in the Grand Conjunction adventure series and adds new Domains. The metaplot of the adventure series was used to update the setting; "David Wise, leader of the 'Kargat' of Ravenloft designers at TSR, has said there were a few reasons for the changes.

Carnival: this domain "wanders the mists" itself, "populated by wild performers and a powerful, living sword". Darkon: this domain is "a broken land [...] whose central castle is frozen mid-explosion, its disparate rooms desperately trying to reassemble the whole in mid-air". "Darkon is now a Domain in decline after the disappearance of the iconic lich Azalin". Falkovnia: in its original incarnation, this domain's "Darklord was a fairly basic analog for Vlad the Impaler [...] and it had few defining characteristics beyond being a land ruled by a brutal warlord with a penchant for ultraviolence". In Van Richten's Guide to Ravenloft, "Falkovnia has been reimagined as a nightmarish Groundhog's Day-style loop, where a struggling nation—which happens to be ruled by a
