yea i spent a lot of time figuring this out only to find that after barry you cant get any farther anymore so its a waste of your time to try.
use to be you had to find a statue in the wisp dungeon after figuring out he had heard the wisp language.
but this point has been removed.
[/ QUOTE ]Barry never heard anything spoken in Wispish, at least not that he's spoken about.
What Barry heard was Yriggor saying "Master open thy door", but all jumbled. This and various other clues lead players to the sword tiles in the Spectre dungeon, where Yriggor was found to have kidnapped Inu the Crone.
edit::
Oh, and you can still get to the Wisp area in the Wisp dungeon, Yriggor's little dungeon, and just about everything else added as a part of the Inu the Crone plot. You cannot necessarily follow all of the steps to learn the information anymore, but you can get to all of the areas, and see about 3/4 of the characters in one location or another.
