Zelda: OOT Comparison

The infamous unicorn fountain.
It was supposed to be accessible to adult link, but was scrapped.
It's possible to get under the ice as adult link using a glitch, but the hole has an invisible wall covering it in both young and adult versions of zora's domain.
There's a path lading down to a very obvious doorway and everything, but as said before, nothing is inside.

The wind medallion/temple is a piece of beta text left in the subquest screen that you can access using a gameshark code.
There is also an ice medallion/temple that was scrapped.
The current ice cavern is thought to be the remains of the ice temple.

Edit- Supposedly Fado was meant to be the Wind Temple sage.

According to that, there are at least two more sages in the zelda canon that weren't in OOT. Fado could have at one point been the Wind Sage, while another character could have been the Ice Sage.
