Possible from "Inside the Belly" Info from Firedemon on BG:
"Just spoke to the one person on Bismarck that sold one to himself last year, and he said that he got it from the quest "Hara-kiri" from Zaldon. He fished up Yayinbaligi in Caedarva Mire to get the ring."
Will attempt to check it out for this game breaking ring!
