Actually the title of this topic is a bit misleading: Barsoom is the world of John Carter of Mars and there are no Drows there. I believe the Drows (in the sense of Dark Elves) were introduced in an AD&D world, not in Barsoom...
In Barsoom there are Black Martians that are kind of pirates, but they are not Drows.

I don't see any connection between Barsoom and Afridhi, however, I do see a strong connection between Barsoom and the Sand Folk. Camarilla's are pretty much Tharks too.
