Alright, so what is the difference between someone who is inside the location of the Time Crash in 12000BC and someone who enters later in 1020AD?
EDIT: I promise I'll be helpful as soon as I get it lol.
Yes, this is what is troubling. By my view of the time crash, it's like a spherical region of space around the Sea of Eden became connected to the same region of space 14,400 years in the future. By this view, if someone was inside the Sea at the time of the Time Crash, they would just be sitting in the Sea of Eden as they remember it. But if they try to leave, they would be sent to the DBT upon passing the boundary. Whereas if someone enters from outside of the Sea of Eden, they would be sent 14,400 years in the future.
An alternate view would be that the space inside the Sea of Eden is displaced, ie: The space inside the spherical volume in 12,000 BC is replaced by the same space from 2,400 AD, and that which was in 2,400 AD "disappears". But if this were so, then the boundary of the Sea of Eden wouldn't be acting like a "Gate" at all and Chronopolis could be said to have been physically drawn into the past, which is why I don't think this is a correct view.
Think of the Sea of Eden in 2,400 AD and using the first viewpoint for comparison. As soon as the Time Crash occurs, it's like the area inside the Sea of Eden in 2,400 AD is physically and temporally isolated from the rest of 2,400 AD. The same thing occurs in 12,000 BC. I imagine that if someone were to try to enter the Sea of Eden in 2,400 AD they would be sent to the DBT, just as if someone were to try to leave it in 12,000 BC if they were stuck inside at the time of the Time Crash. But between the interval of 12,000 BC to 2,400 AD, anyone that enters from the past will be sent to that time inside the Sea of Eden in the future.
Are you saying the Dragon God could rule the world right now and commit genocide on the humans? Also doesn't the Frozen Flame have TTI so there would be two of them still? And what happened to FATE's FF after Terra Tower in CC?
Don't worry, we can have multiple discussions about multiple topics. After all this topic was originally about the ending of Chrono Cross, right?
Our theory predicts a lot of things, and it sets up a generally "Ideal" sequence of events using a very simplistic mechanism which is why I think it works so well compared to the Compendium's ending theory. But one of the things that it does predict is that FATE would not have control over the Dragon God's anymore. We can't predict what that would mean for El Nido though. However, since Serge and Leena still have their conversation on Opassa Beach at the end of the game we can draw two conclusions:
A) Either the Dragon Gods no longer exist for some reason and we would have to explain why
-or-
B) The Dragon Gods were freed but were somehow defeated or neutralized before 1010 AD.
Of those two explanations, (A) is more likely to me as far as coming up with an answer goes, but our theory doesn't predict why they wouldn't exist - it only predicts that FATE wouldn't have control over them anymore.
Perhaps you can come up with something? Our theory suggests that before 1010 AD in the Ideal Timeline history is unnaffected - so everything that happened before 1010 AD is preserved in the Ideal Timeline, which includes the arrival of Dinopolis and the introduction of the Dragon Gods to El Nido, and their sealing by FATE. Any theory that accounts for their nonexistence after 1010 AD would have to explain why they suddenly vanish in 1010 AD, which would not be a result of any Time Bastard effect.
