I'm ready to blow your guys minds…
So first, Zelda, there is a grave (Think Arlington, see pic)
Then, inside the tunnel is the Magical Sword (Think about that song Q posted about. A lot of people called it the Master Sword, but the credits show it's called the Magical Sword. See 2nd Pic.)
Then on top of it, The world of Zelda (NES Version) have underground tunnels from place to place which take you across the land. Including to the cemetery. (See 3rd Pic)
So therefore, I conclude. The Japanese knew! And Time Travel is involved. And this was all put into our video games so anons growing up would be able to see the patterns.
Future Proves Past!
