Explanation:

Carolina and Magdalena put on clothes from the town, They looked like Colombians! They went to the dock. At the back of the place they slowly entered the fort, as they explored it they found a very old room. They went into the room and saw many maps that were from pre-Columbian times.

They checked the maps meticulously. They realized that their map was different and that it led them down a path to a mysterious room. The fourth was behind a large bookster and only by deciphering the secret key could they open it, they tried several times until they noticed that geographical coordinates were the key. A door opened once the bookster moved. A long staircase led to an underground site.
