In the 18th century, Isla Tesoro was under the administration of Magistrate Carlos. The main port was Puerto Dorado, where it is presumed many of the inhabitants of Isla Tesoro lived. Puerto Dorado was at some point assaulted by a large group of pirates of the Wicked Wench who were responsible for numerous acts of violence and destruction; including taking groups of women hostage and selling them as "brides", torturing the magistrate, assaulting the villagers and setting the town itself ablaze.
