Palm Exploded ---> Dark Force boarded Alisa III
Dark Force rests on Alisa III ---> Everything's OK, for now...
PSIV started ---> Things started to go wrong on Alisa III (Orakian and Layan wars)
Or how long after the explosion of Palma Dark Force boarded Alisa III? How long It took for him/her to destroy all the other world ships? I guess this is unknown? I guess he/she didn't just destroy all the ships in one day... More like several years... Maybe 1000 years until it was Alisa III's turn?
So:
Palm explosion ---> Dark Force splits at Noah (or there were already two of them) and goes after "easy targets" == world ships ---> ... which will took 1000 years to complete except for Alisa III where he/she is then captured ---> Some years after (from capturing of Dark Force by Orakio to the time of the last generation of PSIII) heroes at Alisa III defeats Dark Force, finally.
All this is just based on my poor memory. I don't actually remember if Laya and Orakio actually fought each other and Dark Force right after Palm explosion. And then if Dark Force was captured into Orakio's sword for next thousand years? That's the part I really cannot remember. How long did he/she was captured? I guess I have to play PSIII first generetion again, or look for some scripts.
There are too many open questions in the timeline for me.
