Clearly, the more detailed location of the treasure should have been marked by these symbols as well, but further analysis was needed to figure out exactly where.
Of course, the core of such analysis still revolved around the strange symbols carved on the Castle Tower, and they discussed with each other to deduce possible Treasure Locations.
This was not an easy task, but knowing that the core of the symbols carved on the top of the Tower was a map, making a judgement wouldn't be too hard.
For instance, after a careful inspection, they discovered that the four longest arms of the Wind Rose each pointed to a strange pattern, and in the center of each pattern, there was a letter B.
"Could this B stand for Borgia?" Joan asked curiously, looking at the letter. "If I remember correctly, this castle was indeed once related to the famous Borgia family."
