Pirates of the Spanish Main
The youngest son of the tribal chieftain, Lago left the island to gather knowledge about the wider world, so that he might serve as a valuable advisor once his older brother ascends to the throne. After spending years as a harpooner on a Dutch whaling ship, Lago ended up adrift in the Caribbean when his ship went down in a typhoon. Lago was picked up by a passing British Sloop commanded by a Lt Lloyd, and nursed back to health by their surgeon Mark Foster. Lago now feels that he owes Foster a life debt, and agrees to follow the surgeon, when he decides to throw his cards in with the notorious cad Nathaniel Drake.
