Elves new, old, and underground

tcm: why does everyone think elves are exctinct?

why are Orm's Moorish Allies concerned where elves go when they're old (the West, as they say), and more importantly, why are they killing off elves all over the place if their Caliph is half elf?

why do the elves in the Lost Elven City worship the Spider Goddess instead of the good gods?

Chris: Well, according to traditional D&D wisdom, Lloth was a member of the Seldarine, in charge of the Drow, who were some type of elves different from other elves. Who knows? But they all got along, but Lloth was jealous of Corelan Letharian and tried to over throw him. Didn't pan out. So Corelan banished her and her brood to the Underdark. They still want to usurp. I don't know if any characters know this, or if it's true in this game, but that's the old fashioned Forgotten Realms set-up, as I understand it.
