The Precept of a Paladin order has called upon your group to do a favor. Recent initiates have gone to their island pilgrimage where the greatest member of their order is buried. Their vessel is long overdue and the commander feels they may have experience vehicular issues and no cause for 'major' alarm. A vessel has been obtained for you to head that way. Currently the other Paladins are all busy on assignment.
Although set in the Pangia Campaign under 5th edition rules, this adventure setting is easily adaptable to most any game and system.
