This strange ship appears to be of Rokugani construction, but defies conventional shipbuilding practices. Not only is it much larger than most vessels, but it incorporates several unusual elements that are otherwise unknown. Some of which mirror gaijin vessels.
It was found at the hidden port facility and shipyard referred to within the GREEN MOON documents.
Materials found at the port suggest that it undertook a lengthy voyage approximately 20 years ago, in 1102 before returning.
On the ship itself a crew manifest was discovered. Much of it was ruined, but among the few names still visible one stood out: Kasuga Hachiro.
