Are you talking Templar Keys or Mayan Stelae? I had my last Templar Key in Sequence 9 and I'm on my way to get the last Stelae right now.
Can you please help me. I need two more Mayan stones but the location isn't coming up on the map and the area itself is unavailable. How do I change that? I'M quite far. (I know the coordinates but again, cant get there)
