Some may be frustrated that Blackmoor appears so differently in the versions presented by Arneson from what is seen in Greyhawk or Mystara material and elsewhere. On the other hand you could also see this as three or four different sources to steal ideas from for your Blackmoor campaign! My interest in Greyhawk's Blackmoor has been sparked again by various blog posts such as Mortellan's interview with map maker Rob Lazaretti. I went ahead and dug up an old discussion at the Comeback Inn on Fred Weining's take on Blackmoor which has become very influential on how Blackmoor has been presented in Greyhawk material over the last decades.

The little differences are as intriguing as the countless similarities between the different versions. Ramshead has become Ramsgate. The Peshwah have become the Wolf and Tiger Nomads. The Afridhi have been replaced by Iuz. The Duchy of Ten is now the Duchy of Tehn and has been placed in a very different place compared to where Arenson assumed it was. Ripvanwormer made some excellent suggestions on how to compare the different settings in this discussion we had ages ago.

My basic understanding based on most of this so far:

Peshwah=Wolf/Tiger Nomads
Duchy of Ten = Duchy of Tehn
Afridhi = Iuz
Temple of the Frog = Wastri
Maus = Mosshold
Glendover = Glendour
Dantredun = Vestfold (Or could that be Gloomy?)
Tonnsborg = Vestfold
Ramsgate = Ramshold Castle
Dismal Swamp/Gloomy = Gloomfens
Thonia = Great Kindom of Aerdy
The Forest that the Flying Monk burnt down = Burneal Forest (where else could that name come from?)
Bramwald = Bromsage Abbey
The Egg of Coot = The Egg of Coot
Starmorgan = Nevond Nevnend
? = Frost Citadel (AFAIK this is Wolfgang Baur's addition)
?= Kolbenborg (AFAIK this is Wolfgang Baur's addition)
?= Stornawane
?= Trollbar

While it would be easy to get lost in discussions about what is the right or true Blackmoor, what ultimately matters is what is fun in your campaign and mine, isnt it?
