Sorry if I took liberties with the setting for the dark elves. Figured they would have adapted to near pitch black darkness. If you had something else in mind for them, I can change it.

They have... I mean you mixed it up a little, but nothing unforgivable or... really nothing that's not ignorable. In general the way the Drow territory is set up is that the Drow of each region physically represent their region and the god they worship... whether that be red hair for the underground/volcano/cave dwelling drow, or blue toned hair for the mountain peak/outdoor/ice dwelling drow. So technically those guys should have had red hair... but that's the only thing that really makes any difference... and like I said... the difference is totally negligible. Their eyes (like Soza's) are kinda glossed over and reflective to adjust to the darkness in both regions. The ice drow are technically outside, but they live in a land of black jagged mountains and perpetual thick dark cloud cover.

Ah, I see. We never discussed that part. I always pictured the drow as having white hair due to the fact that they haven't seen the sun. Normally, hair color is just how light reflects off the particles that make it up. So, being underground all their lives, they just lose that pigmentation. That's how I always wrote them. I wasn't sure how things were different in your setting with the drow.
