The best thing about the eladrin is that they don't give a fuck about Corellon. Rather than holding out hope that Elf God will forgive them someday, they believe that they will go through the cycle of reincarnation until the end up on the Seelie Court, Unseelie Court, or as immortal archfey. That sounds like a much better deal than the Regular Elves get.
Next up, the Bad Elves, the drow. Like the eladrin, the drow found a new home--the Underdark--and it changed them. One thing I like about the drow: their Ride Or Die attitude. Check it: "Drow view
the elves of the surface world as cowardly children who defy their parents when they're not around but cower in the corner when their parents return, terrified of having their bad behavior found out."
Unlike Corellon, who has put the Regular Elves into perpetual Time Out, Lolth is a more hands-on parent when it comes to the drow: "She sometimes tests her most faithful by drawing their spirits to her in the Demonweb to undergo her judgment. Followers never know when or if they are to be tested."
Woah, drow cities are made within giant stalactites or stalagmites? That's pretty dope. The drow practice slavery, which is one of the ways we know that they're villains, but it's interesting that the book points out that slavery is an economic necessity for them because they just don't have the numbers to survive on their own down in the Underdark. But drow are still elves, of course, so they also use slaves as status symbols.
Drow also get a better deal than Regular Elves: when they go into a trance, they remember nothing. No past lives, just the void. That sounds super relaxing, actually. This also means that drow might not reincarnate; instead, Lolth just makes more drow souls as needed. If true, this means that the drow could potentially out-breed regular elves (since there is a finite number of them) and swamp them en mass eventually.
Blah blah #notalldrow blah blah.
