in which I posted this in th ehtread which had many good and useful ideas on the subject of expeditions to Lost Islands :
... but how about something like this : no limitations, any one can chart a course for the 'Lost Islands' : perhaps by applying an 'uncommon' voodoo card named as such ; Your fleet is then gone for 6 hours on its voyage, you know not where. Upon its return to port you get told its fate : the islands natives may have traded at excellent terms for its cargo, bringing home a great profit in gold coin ; they may have shrugged and sent you on your way with nothing : perhaps your visit pleased the Great Shaman there, who gave gifts of voodoo cards : perhaps you displeased him with your paltry offerings and your vessels were struck by great damage and loss of crew : perhaps your fleet discovered a lost wreck or stranded vessel upon the islands shores and brought it home : and the greatest prize of all : your crew discovered a long hidden temple filled with gold icons and idols... they bring home a full hold of gold bars! Or some prayer mats and a handful of copper statues worth...meh... 200gc.
all in all, I favor the development of expeditions with shiny shiny prizes for the brave...
