Sorry LC, I'm generally not on much on the weekends so I didn't have a chance to respond to you sooner.
Keep in mind that if the split happend in 1010AD then Dinopolis couldn't exist in any dimension. This is because the age of Azala was LONG before any of these events took place and would not be affected by such a small split.
Again, how so?
Here is the order of events, as they occured from a non-linear perspective:
Belthasar appeared in 2300 and founded Chronopolis->Time Crash occured in 2400 sending Chronopolis back to around 12,000 BC-> The Entity reacted by pulling Dragonopolis into the standard dimension in order to counteract Chronopolis -> Serge was born and in 1010 he died -> in 1020 (or 1030, depending on how one reads certain lines) Kid is sent back to 1010 to save Serge -> Serge has a 50/50 chance of life and death, causing the dimensions to split.
As the dimensions split at 1010, they have the exact same history up until 1010, but different "histories" after that point. As Dragonopolis was pulled into the standard demension before 1010, it would exist in both dimensions past (and present, and future).
It wasn't till much later AFTER Chronopolis beat Dinopolis that El Nido was even created.
Sort of:
You're from Medina, right?
I've been on this island
for a year and a half now.
Man, I've had enough.
Aside from the man-made island
with this research center,
there isn't a single island
in the sea of El Nido.
As we see, Chronopolis was built in El Nido, but it was an islandless El Nido. Then the Time Crash occured, then the other islands were built, but for a time it was called "The Sea of Eden" until FATE sealed the Dragon Gods (at which time it regained the name El Nido). As such, El Nido with islands must have been created after the time crash but before FATE defeated the Dragonians or right right after (as the islands were also built to represent the dragon gods).
I still see a problem with this theory however. Why is it that when Crono goes back in time to save the world it affects the REAL world where when Kid does it to save Serge it only saves him in the alternate world? That just doesn't add up to me.
Because when Crono saved the world, it effected the ONLY dimension (and presumably had more than a 50/50 chance). But when Kid saved Serge, it had a 50/50 chance (something very hard to do, as things should generally be skewed one way or the other, even if only slightly). The Dimension Split and in one Serge lives and in the other Serge dies. The one he lived in is set on a course that inherently leads to a ruined future, undoing the work that Crono did. But that work was only undone in one dimension, not both.
Don't you think if a life and death situation caused the split there would only be the two?
Serge living or dying didn't create the dimensions, it was that 50/50 chance. We see from CT that normally changes to the timeline cause the "old" future to cease to exist. Here something different happened: the change wasn't enough to cause the old future to cease to exist, but it was enough to cause a new future to come into existence.
It says his future was split in twain, not the dimensions. By that it simply means that in one world his future was to die and in another his future was to live.
Now admittedly, most people approach the issue of dimensions supposing what we might call a Standard Model of dimensional splits; that is, how dimensions are usually split in most science fiction. Such a model isn't stated in CC (though neither is it excluded), but I am curious; are you aware of this standard model?
Allow me to illustrate; Bob gets up in the morning and ponders if he should have toast or cereal for breakfast. Ultimately, he decided on toast. But... he could have decided to have cereal for breakfast instead. The standard model of multiple dimensions would generally state that both actually happened; in one dimension he had one breakfast, and another dimension was created where he had the other. The splitting of the dimensions was at that moment, however, and the future time of both those dimensions would be different (one might almost say that alternate dimensions are really just alternate timelines).
But that aside, returning to the issue of Dimensions in CC (which may or may not conform to the Standard Model), no. Something can't be said to have split if it was never together to begin with. The futures had to have been the same future if they later split.
Beyond all that, there are a lot more indications that the dimensional split occured when serge lived or died.
According to the shaman,
that's right...
Someone that's not supposed
to be in this world that's
the link to a world that was
severed 10 years ago...
The missing piece of the puzzle.
What has been the significance
of your existence up until now?
On that ominous day 10 years
ago, the boundary of space and
time was torn, and part of me,
in fact, died...
Where even angels lose
their way...
Ten years ago, you died
at this very spot.
There's no mistake.
You drowned.
The truth is, this world,
in which you are still
alive, is the irregularity...
This is the false reality!
Now, go to the place where time
became divided and weave the
threads of time together again...
Chrono Trigger!
Additionally, consider all those things between the two dimensions that are different; you will find that every single iota of change occured after 1010; it is curious that the dimensions would have split thousands of years in the past if there was no divergence between the two. Also note Earth Dragon Isle and Water Dragon Isle; those two islands underwent drastic changes resulting from their respective dragon gods not being present; those changes began in 1010. Why did the respective dragon's disappear?
For that we have to turn to the Ultimania Interview:
http://www.chronocompendium.com/Term/Ultimania_Interview.htmlQuestion: Why do Lynx, Harle and the Six Dragon Gods exist in only one of Home World and Another World?
Answer: Regarding the Six Dragon Gods, originally they existed in two dimensions, but it was made such that each in either word was destroyed. As for Lynx and Harle, there were two of them but Lynx and Harle disappeared in the Dead Sea in Home World.
Indeed, in that interview with Kato we find a few other interesting bits as they relate to the dimensions:
Question: What could be the reason that Miguel was stuck in the Dead Sea? And, were there two of him in existence?
Answer: 14 years ago when he entered the Sea of Eden, he was bewitched. By the knowledge of the future, by the powers of FATE. Perhaps he was overwhelmed in the sea of information, perhaps he became one with Chronopolis. When the world separated into two, of course, there were two of him. The one who was in Chronopolis, was eliminated by FATE, I'm afraid.
Now let us flip the issue around: What evidence is there that the Dimensional Split occured way back in 12,000ish BC?
