I don't think there's any way of knowing that unless you had checked out the muds. After all it's just a list of names of races culled from muds who that happened to be listed on the Game Commandos site in 1999. In many cases I'm sure the race was just a hollow collection of stats with a name slapped on it. Perhaps borrowed from something else and maybe all fluff with no fizzle.

Then again go to your public library and start pulling fantasy or sci-fi books off the shelves, and try to separate the original from the borrowed. But even then beware as dwarves, elves, trolls, ogres, gnomes, giants and dragons have had many different and original interpretations in fantasy literatiure under the same name.

Another poster used the word "resonance" and I think they hit the mark. Not only did Tolkein use it, but R.E. Howard did too. He chose names that were so close to ancient historical names that readers immediately felt comfortable reading his books. Even recent authors like Jordan and Rowlings use historical and mythical archetypes heavily.

Rice's interpretation of vampires spawned an entire genre of gothic-fantasy gaming including muds. Borrowed yes, but original definately.
