" And there’s a chance they could be dangerous, like the tribe on North Sentinel Island.” Dante and Milana obviously understood what Charlie meant. North Sentinel Island was located in the Bay of Bengal, between India and Myanmar. It was a notoriously hard island to dock a ship at, and therefore the small indigenous tribe that lived there had little contact with humans throughout its history. They were known for being extremely hostile to outsiders—and so the rest of the world had let them be. "
