I don't think anyone here was advocating for having massive and complex dungeons here and now?
So ... what exactly were you against in your previous post then? O_o
Not to mention that incidentally we already have a Temple of Selune, burying a section of Underdark hosting a massive ancient forge, on the doorstep of a gigantic temple of Shar, so I'm not sure how the "middle of nowhere" excuse is going to fly.
That is both good point ...
But tell me, how far they are from the beach, where we are told we are in "middle of nowhere"?
No matter if you use Kilometers, or Miles.

Hint: We do not know. :P )
