Hi
Sorry for the late letter, but I couldn't find anything regarding a peaceful tribe. However, my project, which I can't accomplish right now for circumstancial reason, might help you on that topic. A ship was sunk in the Canal Ward; repair it, and you might be able to use it to travel by the Lake.
However, I must warn you of one problem; the Canal is... haunted, or cursed, or what you want to call it.
