After the battle during the meeting of The Movement leaders, I have been looking for more clues. With Dagon and Finawe, we have been sailing around Moonglow, as we heard of some mysterious -and uncharted- isle there. We didn't find any isle, but we found strange wooden posts.
I also travelled with Helium to the Fire Isle, when I found this message from "W". I also found some sacrifical remains, but since then I heard that they have been there for very long. Also, this message has been dropped by Sage Winslow (W), and is related to the fight versus the Followers of the Armageddon (ex Zog Cabal).
