The Nox decided to be pacifists, Asgards kicked the bucket, Ancients ascended (and other crud, not getting into that), but what happened to the Furlings? I think it was mentioned at some point, but I don't remember if so.
It seems to me that in Paradise Lost, Jack and Maybourne are transported to a furling village whose inhabitants died because of a Goa’uld.
But that surely wouldn't new all of them, right?
What do you think?
