This is the full overworld map. Nintendo did not show us this. Some people were messing around on the website and they found this file with the full map. Why would Nintendo leave out details on the full map?
There appears to be one above Skyview Temple on the map in Faron too. I suspect there is another one inside Eldin Volcano.
Also the ship is still apparently surrounded by land even though the map fades out in that area. There appears to be some structure in the distance off the map in front of the ship. Maybe the ship takes you there like the turtle takes you to Great Bay Temple in MM?
The Silent Realm uses the exact same map so it wouldn't make sense for it to be shown. I think I know what you are trying to say though. We can expect alot of content in each area so even though we've seen the whole map, there will still be surprises.
It can't be the Arbiters Grounds as that was not part of Hyrule proper at all...
Good this have something to do with the Triforce of Power...Ganondorf (I know he's not in the game but...). Also, the one above the Skyview Temple could represent either the Triforce of Courage or Wisdom.
What? Yes it was. It was in the Lanayru Province, which is part of Hyrule.
Wow man. You are very sharp
By the way: isn't that ocean made of sand instead of water? Like a sand-ocean.
