Ah, I was going to add a footnote about Labrynna (and Termina, and also the place from Oracle of Seasons whose name I can't remember,) but figured it was unnecessary, then forgot to remove the asterisk :v
Holodrum was the one from OoS. I wouldn't count it as an actual country for the same reason that I wouldn't consider modern Labrynna to be a country. They're both more like city-states, with Horon Village seeming even less developed than Lynna City. Termina is certainly another land, albeit an alternate dimension. In that case, we could also count Lorule.
But I was also thinking about how in the opening Harkinian is planning to offer military assistance to Onkled using the Triforce. It's something a bit more... realistic, I suppose? than the typical Zelda fare. Just something different from the usual portrayal of Hyrule as this 100% isolated place where the Triforce is kept (and, in later games, implied to not be used. Mostly unrelated ,but something I liked about the earlier games was that the lore stated that the rulers of Hyrule used the Triforce to bring prosperity to Hyrule, implications that are more or less totally missing from Ocarina of Time onward.)
Yeah, actually making use of the Triforce would be pretty cool. It could also serve as a bit of a deus ex machina, though, given that the Royal Family could just wish all of their problems away. Realistic, but not terribly practical for the story.
Iirc Ordon in TP was technically an independant state that payed tribute to Hyrule.
This is certainly a possibility, but it's not stated outright; Rusl talks about "Hyrule" like it's somewhere else (in the context of Link traveling there to deliver the Ordon Sword to the royal family at the start of the game,) so it's not exactly unlikely, but it's vague enough that it's possible that Ordon is considered part of Hyrule, just not "Hyrule proper" (in the same way that, say, Puerto Rico is part of the U.S., but isn't typically considered a "normal" part of the U.S. due to being a territory.)
I was under the impression that it was a separate entity, given how Link is specifically referred to as an "Ordonian" once or twice. Seemed a little odd, given how the typical demonym is Hyrulean. However, your Puerto Rico analogy is just as apt.
Man, that earlier stuff... in that, the triforce is not something you want to actually use because it's something that can fuck with you hard, from what I recall. I still very distinctly remember link growing tusks and becoming massively aggressive after picking up the power one. Was in one of the comics, not the games, but... still. Dunno how prevalent it is in the newer stuff, but there was definitely something of a thread of thought in the earlier about how the triforce had some serious mental side effects going on. Power was the most obvious, but iirc even courage and wisdom would screw with you, never mind the whole thing. Basically not something you use very often/at all, lest you turn into a giant world conquering pig or somethin'.
Never actually read those comics, but that sounds really interesting. I doubt that we'd ever see anything like that in the games, unfortunately, since it's already been established that if Link is going to change into something, it's going to be a
wolf or a skeleton fluffy pink bunny.
