Sir Stefan Mills

Now deceased, Sir Stefan Mills, formerly of Ludendorf, is a researcher and writer whom, according to Van Richten, did a poor job of researching Nidala and mistakenly referred to it as "Nidalia". This appears to be an Easter Egg reference to real life Ravenloft contributor and author Steve Miller, whom was one of the authors of Domains of Dread, a source in which Nidala was referred to as Nidalia.
