Endur said:Q1 (and later novels based on it) allowed adventurers to kill Lolth in the Demonweb as part of a campaign based on Greyhawk.
I'd have to double-check the FR sidebar, but offhand I'd say that unless there is more than one Lolth and more than one Demonweb, killing her in the Demonweb kills her no matter what world you are from.
The events you are recalling are from the Greyhawk novel, Queen of the Demonweb Pits by Paul Kidd, the third book in (what was apparently) a trilogy about those characters.
johnsemlak said:They weren't a trilogy exactly. The first novel, Against the Giants was based on a party of adventurers lead by a Fighter named Vlander. I forget the author. The novel wasn't very good, but it adhered pretty strictly to the modules. Paul Kidd's novels Descent into... and [Queen of the Demonweb Pits[/i] are connected I believe and both feature Justicar and his pixie (or sprite?) friend.
