The other 2 locations are just for decoy, well, I kinda need to post a drawing of the full map, but I will try to explain. So the map consists of 4 islands, 1 Dome of Confusion at the north, 1 Mt. Grim at the east, 1 Temple of Gods at west and the island of five locations in the middle. They are all connected. So there are 3 swords so the other 2 locations are just decoys/traps. You can't expect to find the sword easily xd
