Yes! Valley of Sorrows.
But nope. NEVER had been there before then... Had no clue where it was, cause for years I've gone through Cape Terrigan just to get to Korroloka or Gustav tunnels for whatever reason.
Maybe there are certain zones that are hidden, and others linked to other zones.
(Though I very well might have gotten lost way back when I was new and somehow wound up there... It's a possibility, but I don't believe that happened... L0L)
