The Legend of Turner

Ancient legends tell of a ship, stranded on a remote island in the darkest seas, that hides a treasure of incalculable value that no one has managed to find... until now. Over the centuries the legends of the nao, whose name cannot be spoken, have faded away and only whispers shrouded in mist have reached us, that Turner, the fearsome pirate, set out in search of it. After sacking the port of Tripoli he found an old map and with his boldest sailors sailed according to its course but... never, never again was anything heard of them. Now, what appears to be a rather special old chart has been found not far from here... Could it be Turner’s map? Could the legend be true? Only someone truly daring would dare to undertake this adventure... Is that you?
