TWW established that the Triforce cannot leave Hyrule, so when Link went to Termina, it wasn't with him anymore.
No it didn't. Established that he lost the Triforce because Link LEFT THE TIMELINE.
The ToC can't leave Hyrule. That's why it didn't travel back with Link from the AT, but instead split into eight shards. So, it's not stupid. It's based on canon.
See above. It is stupid, because Hyrule isn't the entire space-time continuum, and the Triforce is responsible for maintaining all creation, not just Hyrule.
That was the smallest part of my response.
Focus on this instead, the main part of what I said: We don't see the ToC til he's in Ganon's Tower. That's really the only time he had the ToC, plot-wise. As soon as he gets the ToC, he heads to confront Ganon.
He had the Triforce of Courage ever since he woke up as an adult.
Well, Hyrule as in the realm of Hyrule. If it physically can be taken from one realm to another, I don't see why it physically can't be taken from one timeline to another.
I've already explained this to you. Every world that you can conceivably access are in one timeline. Not just Hyrule's time split, but probably also Termina, the Minish Realm, the Twilight Realm, etc. etc. Infinite worlds, two timelines. You can't take the Triforce across timelines because the other timeline already has one.
If the Triforce split, Zelda would have her piece, and Nintendo wouldn't forget that if they were trying to imply Triforce possession. I think that it's more likely that the mark appeared for more AoL/OoX-ish reasons, despite the prominent ToC. That would be because he's aligned with that force, or something. He was already "chosen by the gods" and "a fated hero", right?
Maybe the other two didn't receive theirs yet, fuck if I know. Still, the mark is there, and it glows on a central piece, so that means he has a Triforce piece.
Judging from his ears, Ganondorf had the ToP before the execution scene in TP.
His ears have nothing to do with having the Triforce of Power. Ganondorf gained demonic features like pointy ears and sickly green skin because he established himself as the Maou/Demon King.
So it would be a problem for AT Hyrule to be missing its ToC due to traveling across timelines, but not a problem for it to be missing from CT Hyrule while its another realm? You're not being consistent. Termina is a completely different realm than Hyrule, so if you're insinuating that the ToC ditched Link in the AT and shattered because he was leaving to a different timeline, I don't see why it wouldn't ditch him if he left Hyrule altogether.
Already addressed this. Hyrule and Termina are two different worlds, but they're in the same timeline. The Goddesses left the Triforce to govern ALL CREATION, which would mean all of their worlds, not just Hyrule. The two timelines can't interact with each other whatsoever, the Door of Time was closed.
So, as he traveled back and forth within the single timeline of OoT, the ToC kept leaving him and coming back to him because he wasn't of age? I don't think so. The ToC didn't have to do with him being the Hero of Time. I'm pretty sure the ToC went to him because he was the most courageous person at the point when Ganondorf touched the Triforce.
The timeline was still singular during that period, so he kept the Triforce, as the times he kept traveling back to were post-split. Only when the Door of Time was closed were there two timelines, and thus two Hyrules, and thus two Triforces. The Triforces went to their owners not based on who's most courageous or who's wisest, but because they were the chosen Hero of Time and Princess of Destiny.
Actually I don't think it's all that stupid that the Triforce can't leave Hyrule, just like it can't leave it's own place in the time and go into the past lest it craet a paradox with two TOC's in the CT and none in the AT. It can't leave Hyrule's dimension because it would upset the balance of the three parts of the Triforce. It can be shattered into smaller peices but not moved to another dimension/time. The sahttering of the ToC I always believed to have been caused when Zelda sends Link back in time the final time, which may have put a strain on the ToC since it wasn't same way he traveled back in time the other times before and the ToC was forced being forced back in time but couldn't make the trip because it would of the paradox it would create.
What paradox? If Link took the Triforce of Courage with him to Termina, that's no big deal. The Triforce governs the cosmos, and if someone wants to reunite the pieces, they can take that portal in the Lost Woods. It's still there, since Link uses it to go home at the end.
Says who? You're making up your own rules at this point.
His "rules" are based in common sense and understanding of what we're told about Hyrule's cosmology. You're the one making up (or parroting shit other people made up) crap like "The Sacred Realm is timeless."
