DANG IT. I just lost a nice big post. Oh well. It was just about the number-alternate-realms theory. Basically, I like the idea but I don't know if it's worth a lot of thought.
1- Sacred Realm- 1 well-known inhabitant (Rauru); the full Triforce
2- Twilit Realm- 2 well-known inhabitants (Midna and Zant); two Sols; four pieces of the Fused Shadows (two is closely related to four, i.e. 2 squared, 2 x 2, 2 + 2)
3- Hyrule- Multiple groups of well-known entities/inhabitants, most of them are in groups of three (goddesses, Ganon + Zelda + Link); three pieces of the Triforce
4- Termina- The four giants, four dungeons, four parts of the clock, so on.
Interesting to note though is that 1 is a holy number, as it is a number of wholeness, and is fitting for the Sacred Realm. With the Sacred Realm being the closest dimension to the gods/goddesses, it makes sense that it gets the holiest number. Three is another number that is considered lucky or sacred, and as Hyrule is the next closest to the gods, Hyrule is based around three.
Now the Twilit realm seems to be based on two. There's not much to support it other than what I listed. But two is between one and two, so it's not quite holy nor sacred nor lucky. While they are not closer to either despite 2 being closer to 1 than 3 is, it shows the mentality of the Dark Interlopers. They wanted to be more powerful than Hyrule, but now they're stuck in a limbo between where they were and where they wanted to be, but they are actually farther from the power they wanted.
Termina though is on the other side of Hyrule. They don't want anything to do with the goddesses or the power they possess. They want their own power, so they make it themselves. There's a similarity between Termina and the Twilit Realm just as there's a similarity (relationship) between 2 and 4. Both want power, they both sought an evil power (and the two powers they sought look similar).
That's all I have for now. There's not much significance to the idea, but it's interesting.
