Dopplegangers, or ghostly doubles, are rare creatures that take on the form of other living people. Unless they've given up, dopplegangers are in constant search of the person they are the copy of. If they do not find the person they match, the doppleganger's body will die (just like any other human being) and will be reborn into a doppleganger of someone new, beginning the search all over again... and again... and again for all eternity.

A doppleganger will only stop being reincarnated when they replace the person they are double of. Said to be evil or sinister, suffering through the pain of death over and over leads dopplegangers to murdering the person they are the copy of. Assuming their persons identity, if they actually find them (an extremely rare accomplishment), is the only way to become a doppleganger no longer.

All dopplegangers remember all their past lives and, because of that, typically choose to live alone. Some, though, do find companionship with one another and decide to live together and need not search for whom they are double of.

There are no known tribes of dopplegangers, but a few do live on the island.
