So I don't know if this is already known or not (probably is) but I thought I'd just put it here that
Teresa Wright Allwave is located in Abura and while we're there someone should talk to her about her grandmother
Charm Wright and what happened on that voyage. Likely she knows something about it, probably heard stories that the crew came back with, which could be useful when going to Darva.
(I'm almost entirely certain this is already part of the plan, but if not I thought I'd bring it up.)
