Yes, when they said it takes place after OoT, I took it as in right after it. I didn't really entertain the idea of it being after more than JUST OoT. I suppose it could be possible, but that's not how I interpreted it. Still not quite sure it would fit there, seeing as the Shieka built all the guardian tech and everything else 10,000 years before the events of BotW, but the tribe was nowhere to be seen in TP, nor was there any sign of advanced tech. Guess we'll find out for sure when they officially stick it on the chart.
Not really, I'm willing to debate the idea, so of course I'm going to voice any conflicting thoughts I may have, but your theory just plain doesn't make sense. The part I argued in my last post is not "speculative." The events of BotW are proof enough that your suggestion could not be the case. I'm not trying to scream "YOU'RE WRONG!" in your face, its just a fictional story from a video game with spotty info at best, but if we're going to analyze this, let's at least do it using some logic.
