But haven't they forsaken Corellon and the faerie elves though? According to what was covered in "Evermeet", they care nothing of the tree of life and I deduct that it means nothing to them and holds no power over them. Unless it does, and it's destruction would render them into the same boat as the surface elves, which in that case means they don't realize the importance of it?

I would say the first ever drow(s) may be affected, since they were once true elves, but the ones that now populate the realms I doubt, since they are a far cry from the original drow, and have their own unique abilities, affinities, culture, religion etc. making them like you said, the spawn of the spider-queen. I guess at some point they become their own race?

I too would agree about how the recreation would go about. IIRC there are celestial guardians assigned to the tree as it is, making it quite hard for any mortal to run afoul.

Good topic though, but we really can't know past where it was covered in FR literature. I am quite interested in the drow lately, even though I purposely avoided them in the past, mostly due to the horrible hype surrounding Drizzt and co. back then.
