Could Termina potentially just be subterranean?
So, first off, it needs to be said that it's been insanely vague as to what Termina is suppose to be over the years. Like, more vague than even most Zelda lore gets.
One common idea is that it's actually a sort of imaginary world created by the Skull Kid using the power of Majora's Mask, or whatever it is the Zelda Encyclopedia says.
Another idea, or at least so I've heard, is that some guide from way back in the day quite literally calls Termina another world. Then again, I've also heard people say that the original Japanese is vaguer and could mean that Termina is just another land.
Finally, there's an Aonuma interview from around the time of MM3D coming out, and he makes it sound like Termina is actually just another country in the same world as Hyrule.
In the event we go with the explanation that it's another country, I've seen a lot of people question how exactly that can be reconciled with Link falling down that giant drop at the start of the MM in the Lost Woods. My question is: What if Termina is actually just a subterranean world like Subrosia?
It has a sky, but underground worlds in pop culture being so deep that they have their own sky and biomes is nothing new. Furthermore, while I haven't played the Wild era games, I've seen people say that there's a gigantic, bottomless void somewhere in TotK. I'm not saying that's where Termina is, but it shows that these massive distances can theoretically exist in the setting.
What do you think? At least vaguely interesting to think about, or total nonsense?
