The Evil thing is a bit of a red herring for this discussion. I'm only really brought it up due to a comment Rich made in one of the commentaries about evil underground counterpart races (hence my joke about the deity that insisted every PC race have a more powerful underground counterpart). I was mainly asking if Duergar are considered Dwarves for the deal with Hel, or due to the massive differences between them and vanilla dwarves, and the fact that the word "race" was used when it's not the same as "species", are they considered a different race than the dwarves that Durkon belongs to?
