1. In Hyrule Tower (where you fight Agahnim for the first time), there is a 1F on the dungeon map. You enter on floor 2F, and continuously progress upwards. Does the floor even exist?
2. In Misery Mire, there is an empty room shortly after getting the Big Key. Inside the room however, there is a pool of water which looks like it should be a fairy pool. Does anyone know if there were initially plans to make that room a fairy room?
If anyone can answer these for me, my curiosity will be satisfied.
Hyrule Castle is two dungeons. The first one has you enter on 1F and proceed into the basements to rescue Zelda from her cell, and the second one has you enter on 2F and proceed up the tower to stop Agahnim from sacrificing Zelda.
Not to my knowledge. It's just meant to be a room with a teleportation tile, and I guess they thought the room would look half-assed if they didn't put SOME kind of decoration in it, meaningless though it may be.
I guess you're right on the second one. On the first one though, that still doesn't explain why 1F appears on the map in the second Hyrule Castle dungeon.
