Halark (and by extension, Dorcha), Morrin, and Whisper are all traveling together too? Morrin and Halark are searching for the same (?) unspecified lost artifact for the church of Kelemvor? And Whisper is a friend to Halark, that much I'm sure of. Taesshan is looking for a strange spring that is also Undinar's life quest to find, and Undinar has been hired by Winter as a guard... And Winter's in Mezro as a diplomat, right?
Do I have all my relationships correct?
Was anyone already in Mezro prior to today? If not, are the two groups even on the same ship?
