Received origami note: fuefuki maru. Checked Otosan Uchi and Slow Tide Harbor without luck. Investigated records at Kyuden Kasuga while checking to see if anyone was looking for Kasuga Osamu. Nobody seemed to show any particular interest in him or his whereabouts. Found a reference to the Fuefuki Maru in connection to a woman named Kasuga Yuto who died while serving on it in 1103. Further records were apparently stored in secure access.
Broke into the library, subduing the librarian. While searching the massive records room the phrase GREEN MOON stood out. This matched the green origami moon that the note was written inside. Details of Yuto's death were being suppressed by Kasuga Kanami. The rest of the box had been largely emptied with numerous scroll cases containing nothing. A scrap of paper remained: “even with the death of the gaijin, our efforts have been largely successful. While the ship will need to launch from the secure port outside of Kiken na Roka Toshi, experienced crew should be recruited so that the voyage can proceed as soon as possible.” The bottom of the box had a few strands of finely-shredded tobacco beneath the empty scroll cases.
