Yeah, that's obviously as legit as my approach.

- My reason was, more than anything else, my desire to give Blackmoor a distinctive visual model in my mind.
Means, if I picture BM as LotR, it will become LotR.
If I picture BM as Vampire Hunter D (Steampunk), it will become Vampire Hunter D.

So, I chose a rather unconventional setting, basically Rosemary Sutcliffe's Eagle series,
as an approach to the universe and added everything else up to this base.

Why I chose that visualization? I don't remember any more. :)
