Thanks!
I will send Jason an E-mail when I get a chance. From the e-mail I couldn't tell if it was a one time thing or not. I was going to hang around the lists before asking.
Weak spoiler to well known adventure below -
Grodog, are you the same grodog that has an interesting study of the Lost Caverns on his site? If so, thank you - I loved it. One thing to think about - I always got the impression that Iggwilv was using the Lanthorn to cure her daughter of her condition. That would explain why it is lit in the modual (which means that it was at least semi attended) and would be a reason for the imprisonment.
