Deletion of Underdark (2nd nomination)

Comment: As the nominator notes, there are independent sources on this article, although I am not so quick to discount the ones presented so far or to doubt that there are plenty more out there. When this article was Wikipedia:Articles for deletion/Underdark|first nominated for AFD back in 2008, it was closed as a |snow keep, and at that timehttps://en.wikipedia.org/w/index.php?title=Underdark&oldid=236732488 it had none of these sources at all. I don't see why meeting  should be in doubt on this topic, and AFD is not cleanup
