Simply speaking, it is possible that Dark Falz in PSO1 was only believed to be destroyed despite"He is pso2 sales dead because we said so." His return and destruction of Pioneer two would awake the Oracle fleet. In turn, ARKS would assemble to defeat him. Then they'd then possess the understanding that Dark Falz cannot be destroyed, only sealed. Thus resulting in the occasion point 40 years back when Dark Falz was closed on Ragol/Naverius. In the event the Photoners that fulfilled with Xion and built Oracle were Pioneer 3 (as explained in another thread here), it'd really still drop in line. The only confirmation in terms of time passed is that Dark Falz Elder was sealed away.

This calls into question several things: Why was sealed in a spot of ruin? Did the heroes know he had to seal him and therefore couldn't be destroyed? And how could they have have the ability to seal him rather than foolishly attempt to ruin him? The notion solves this that the Photoners Xion mentions were simply Pioneer 3 that met Xion. Pioneer 3 would have known from Pioneer 2's data what Dark Falz was (and then that he couldn't be destroyed based on their attempts in Episode 1 and 3). Xion could lead to her being the ability to seal Falz Elder's origin. And lastly, since Xion was their technological catalyst which allowed them to respond quickly, the heroes might have responded to the destruction of Pioneer two even though they were finally too late to save it.

The construction of wopal was done by Luther, and recent that the natives didn't forget ARKS ops' language. Enough that they were fluent in said language. If they had more than several hundred decades, it's more probable they would have adapted over simply a dialect and rather developed their own language based on ARKS language. Very similar to Spanish and French are derived from Latin, nevertheless distinct from one another. There is also"dead languages"languages that fell from usage over time.

In regards to Falz Elder being sealed on Naverius along with a renamed Ragol, ARKS could have been able to quickly respond with their new technology from Xion. So while they could have been too late to save the colony made from Pioneer 2 and its inhabitants, they could still have arrived in time to seal Dark Falz Elder as he was through the occasions of PSO. This can be further supported by the concept that Photoners were just humans/newmans with Photon Aptitude at that time period that the events of PSO/PSU/PS0 performed. It's also entirely possible that the Photoners were people hand-picked by Xion from the group, with Luther being the sole survivor once the times of PSO2 come about.

A lot of this doesn't line up with lore. At one point I believed that Pioneer 3 started and it was the ship that discovered Xion, but what causes to not work out is the fact that the photoners did not even understand what photons were earlier finding Xion. That right there pretty much breaks any possibility that PSO2 is a sequel to PSO because the Hunters were already using photon technologies on Ragol. You can also locate the roots of it via the Ruby Bullet's description.Where was this? Since it doesn't make sense to buy Phantasy Star Online 2 Meseta call them"photoners" if they have no knowledge or capacity to use photons. That's like calling a species of bird"crawler" when it mostly flies, nests in trees and preys on fish.
