The characters from the television series Black Sails do not explicitly move to Treasure Island in the narrative sense, as the series is more of a prequel to Robert Louis Stevenson’s classic novel. Black Sails, which aired from 2014 to 2017, explores the backstory of several characters found in Treasure Island, including Captain Flint, Long John Silver, and others.
Throughout the show, we witness the rise of piracy and the politics of the golden age of piracy, setting the stage for the events in Treasure Island. The timeline of Black Sails takes place approximately two decades before the events described in Stevenson’s novel, which means the characters are portrayed in their formative years, rather than as they appear in Treasure Island.
Therefore, while the characters do share a narrative lineage and thematic elements with Treasure Island, they do not transition or move directly between the two stories as one might think. Rather, Black Sails serves to enrich the background and motivations of these characters before they appear in the original tale of treasure, adventure, and betrayal.
