Yes, you do in fact haev to kill the gnomes that tell you to come back in a
few weeks. I read on a site that that someone got three of the lenses one
fron the dark elf and two from killing the gnomes that tell you to come back
in a few weeks. This is only what he said, so it looks like we will have to
kill some of our own brethren to get the quest done. But it's still that one
last lens thats missing. I also heard that someone saw Bidl Frugrin in the
clutches of the evil Erudites in thier palace. I'm going to check it out
soon and make a new character and see.
