Dear GrayLensman,
...
LAVOS WAS RESPONSIBLE FOR THE F.'ING TIME GATES.
During the Ocean Palace, Lavos is awakened, and Janus and the Gurus all get warped through time.
Then, Magus summons Lavos in 600AD, and this ends up opening ANOTHER Time Gate, warping our heroes to 65million BC, and Magus back to 12000BC.
After Lavos crashes in 65million BC, it leaves the Time Gate that leads to 12000BC and thus Zeal...IN THE VERY SAME CRATER IN WHICH IT LANDED!!!
THEN, in our FINAL BATTLE with Lavos, Lavos uses a timewarp technique that warps us through the different time periods, thus changing the background imagery, and the different techniques that Lavos uses.
HOW CAN YOU NOT SAY that there is definite cause-and-effect relationship between Lavos and the Time Gates?
What more evidence do you need than that?
Why do you hold onto this "The Entity Did It" theory? C'est ridiculement!
No, no, no...my point is, The Entity is not a physical entity like Crono & co, who can act in the third-dimension and whose actions would impact the timelines.
What you said is that, in the original timeline, Janus and the Gurus got killed. Then The Entity rewound time, and gave them the Gates the second time around.
You're saying The Entity is like an invisible hand that can do whatever it wants!!
I think that the Entity is the planet and every living or non-living thing on it, in a physical and a supernatural sense. The only thing not part of the Entity is Lavos, because it is an alien. The time travelers are not separate beings, but the physical form of the Entity's attack on Lavos. The Entity's consciousness transcends time, and parts of its physical body are also capable of time travel. The Entity can change the timeline by sending part of its body through a Time Gate, which it appears to be able to create arbitrarily.
If the Entity was responsible for the time portals in the Ocean Palace, it was capable of seeing an event which it wanted to change and sending a time traveler through a Time Gate in order to create a new timeline.
Too bad that, The Entity didn't have any other physcial bodies to work with to create those Time Gates in the Ocean Palace, other than Lavos, which The Entity can't control or work through.
Besides, if The Entity really DID create the Time Gates, it would've created them in far more convenient locations than it did.
The Entity: "Hmm...65 million BC...where should I put a gate? Ahh, Mystic Mountain! I'll put it a few feet off the ground! That should give them a little chuckle!"
...
It is clear that the Time Gates were created from Lavos's own radiaion, which it couldn't control. A poisonous snake, a poisonous spider, and poisonous frog can't control being poisonous, and neither could Lavos control being radioactive, and that lead to its own downfall.
...
IN THE VERY FIRST PLACE, Lucca just happened to have a matter transporter, and Marle just happened to have a pendant that could alter the machine to open a Time Gate, and that's because the pendant possessed a stone that was made by Lavos.
The two together had enough power to open and create a Time Gate, and were lead on their journey entirely by chance.
The Entity may be in
Chrono Cross, but I don't see any instances of it in
Chrono Trigger.
