Halflings live on an island south of the main continent. At the age of 22 they are considered adults and there is a big celebration ending with them being shipped off to the mainland. They must stay there and explore and learn about the other people and cultures for at least a year before returning. If they do not return within 15 years someone from a special order of halflings is sent to find out what happened to them. If they are still alive they are returned home willingly or not. There is always a large celebration when a halfling returns from their wanderings. These laws were implemented after the halfling population dropped because few were returning from the wandering.
