Then they fill the ship with riches like jewlery, iron, steel, coal, limestone, the best healing food ect ect. After that, get one guy (Jos maybe *shrugs*) have a lone character sail it out, out, out all the while keeping track of his movements untill he dies and the ship and riches move no longer...
Then his record of movements would become a "treasure map"... It could then be scattered through out the entirety of Cantr or even several seperate ones for other language areas that are used.
