Here is a screen I made of a map, on a wall, next to a pirate's cadaver.
We can see some tags showing up the boss, and what seems to be a teleporter to a (secret?) zone in the south est of the map.

-to my mind, I found it Is the special mission map, the only one (u_u) provided, but not sure.

Anyone has a clue, or any experience? :O

It's a map for the hidden pirate treasure. It's in the tomb on Noctis Labyrinthus. The area at the bottom of the map is the entrance and the drawing shows where it's hidden. You need to go to that spot and hit the wall, which will then break and reveal the treasure.

Oh really, that's what that is? I saw it and thought "hey this is a map of the tomb" but I didn't think any of it.
