1. I don't think they specified what color the gate that Janus & Melchior went through...anybody got the exact quote?
I was going to get it from the script in the Compendium, but it's not working. Its possible that it was described as being dark rather then black, but that would still require another color (as red, green, and blue hardly qualify as dark).
2. Magus' weapon was not dreamstone when you fight him in his castle.
I never said it was the weapon he was using I just said he had it with him (after all Crono could of had the Wooden Sword with him, but that doesn't mean he was using it when he fought Magus). How else would you explain him having his dreamstone weapon in Zeal if he didn't have it when we was pulled into the gate? I don't know about you, but I doubt Zeal had that much Dreamstone lying around because then you'd see it a lot more (besides the Mammon Machine and Magus's Weapon we only see Schala's Pendant, and the Red Knife (both of which are pretty small).
3. This theory fails to explain most of the gates that already exist...
Really? Hmm... I said I wasn't doing the Green Gate.... oh you mean the pillars & the bucket at the End of Time, right?
Well, I've always believed that the pillars slip you into an already existing gate stream, going in a predetermined direction. Although come to think of it that doesn't explain how the micro-gates on the other end stay focused enough for you utilize the gate.
I'll have to think that part over.
As for the bucket I believe it works just like the pillars.
The way I see it, it's just as they said during the 400 Year Reunion (I always feel like I'm messing up that year...600...1000...right...)...The gates are created by the entity so that Crono & Co will help to finally defeat Lavos...
True, but you have to recall it was just a hypothesis. Assuming it's correct it still leaves open the question as to how the Entiy created them which my theory could be used to explains with "it put the energy neccesary for dreamstone to generate micro-gates in place".
The main thing I noticed about the portals was, like a man reliving his memories at death, that they all happened to occur during drastic, momentous times on the planet (ie the Coming of Lavos, the Fall of Zeal, the Guardia/Mystic War, etc).
Lara losing her legs. . . nope doesn't seem like a symptom of drastic, momentous times on the planet.
Millenial Fair drastic, no. Momentous not when the planet and for that matter humans are well over 65,000,000 years old.
End of Time: The Planet isn't even there.
