About the Isla de Tesoro map

Hello.

This time I bring you a creation called Treasure Island, it is a map that I have built myself as a hobby.

The story takes place on an island containing the ruins of a civilization with great treasures, discovered by explorers from the Steampunk universe who are building a base and claiming the island.
