We found Capt. Johannsen on the Island that Comes and Goes. She is a famed (or infamous) sea captain. Years ago, her crew mutinied and set her adrift with a knife and a waterskin after refusing to follow her orders to sail north. After drifting, she arrived at the Island that Comes and Goes and convinced the islanders that they should accept her as their leader.
She survived for decades on a few plants, sea gulls, and the occasional humans who also found their way to the spirit island.
She’s now reborn as a much younger woman who does not remember her life as a cannibal.
