All Pirate Stories are not Legend: 6: Pirates of Utopia

Legend has it that there was a secret pirate society operating near the island of Madagascar. It was known as Libertalia. Henry Avery and Thomas Tew were members of this society. The pirates gradually took over an area of the island and created their own territory with was ruled by pirate law. It is said that the society terrorised anyone who approached the island for years and then suddenly they disappeared and the land was returned to the locals with no explanation.
