[sblock]Lolth got pregnant and split herself into many small spiders, which caused her to go silent. She didn't bother to tell her clergy, who weren't too happy about this.
while other groups attacked cities loyal to Lolth*, the spiders ate each other. It was natural selection - for the strongest spiders, and then for those smart enough to hide their strength.
Eventually, the smartest spider somehow turned into a new deity
or something like it (I haven't read the last one in the series, and I don't want to anyhow) just in time to save Menzo. Well, I think Lolth's clery did the actual saving, of course. Just what the Realms needed...
another deity.[/sblock]
[sblock]*That series had some interesting drow characters (except Halistra, may she be sliced up by a confused Dalesman), but it still had the stereotypes of drow pulling everyone's strings (and if that's bad, what if they're half-dragons

), drow being so "scary" that dragons fear them, and drow being way more skilled than anyone else. Oh yeah, and any female drow exposed to a follower of Eilistraee becomes another follower of Eilistraee due to that weird E-virus. Even Danifae might fall for it, but I don't want to read the last book in the series for fear of being proved right.[/sblock]
