Ravenloft is a dark gothic horror campaign setting, consisting of a number of mist-shrouded extradimensional spaces known as the Domains of Dread.
Each domain acts as inescapable prison, trapping a powerful and evil Darklord in an ever changing reflection of the dark lord's psyche.
The malevolent mists of Ravenloft can swirl up unpredictably and transport other people into a domain.
They also form a thick, white, and impenetratable barrier that prevents travel between domains, only rarely permitting passage from one domain to the next.
Mistrealm is a homebrew campaign setting that is similar to a Ravenloft domain.
Mistrealm is also my personal collection of miscellaneous unrelated links and articles on various topics.
There are lots of ways of being miserable, but there's only one way of being comfortable, and that is to stop running round after happiness. If you make up your mind not to be happy there's no reason why you shouldn't have a fairly good time * Edith Wharton
