After surviving a near death experience, a group of children were brought together and raised by a travelling group of "merchants" (Gypsies). The party grew up together and were the only survivors after a mysterious illness killed all of the other members of their gypsy caravan. Now they've taken over the job of travelling between the towns on the island nation of Firin and searching for the artifacts their mother told them of during her last dying breaths. All the while trying to figure out which of their siblings are meant to betray them.
