I hate to break anyone's hearts... but I do not believe even the last thread here is truly the last thread. Because if I'm not mistaken and remembering correctly (and
@Morrus would be able to confirm)... I want to say there was one (if not a couple) massive message board losses back in the early 3E era. Where the entire system had to get wiped and started anew. And I don't believe Morrus was able to save old threads when the new boards got up and running (or at least not all of them), so I think the true starting point of the EN World universe is truly lost to time.
