So I'm thinking we're in for another 2.5 series of events in 4.5. No, not the "bloody banquet" as it was, but rather we fail at performing a duty. So, read me out here.
Let's say in 4.5 MS Part 1 we have a moment with Hydalean and for some reason, our connection to her is severed completely. Thus, we wonder the realm not knowing what to do next. Pretty sure we have to fight Zenos-Elidbus again in Part 1. However, after that and failing Hydalean, we are weakened with no will to go on because we did not bring forth the "flood of light" as the WoD told us in 3.4 and 3.5.
Now onto 4.5 MS Part 2 after weeks of wondering the realm with our lost blessing of light if we do lose it, we come face to face with those of the Light. Hence the WoL getting rekt in the Shadowbringer Trailer by some Amdapor Hard beasties. After a fruitless battle we are beaten truly and unable to go on. Unable to get up. So, in our moment of defeat, we hear the voice once again "Throw wide the gates so that we may pass." We attempt to resist, but we can't. Thus the WoD comes back and talks to us. Asks us that balance must be bought to the shard and in order to do so we must accept the darkness or their darkness to beat back the flood of light. This goes back to the Twin Calamaties which I think now mean the two stars.
So once that is done, we absorb the power of darkness. Getting Kingdom Hearts up in here and use it to beat back the light and thus through 5.0 we seek balance between the Light and Darkness. Balance between Hydalean and Zodiark. But the Ascians as we know, seek to undo that balance.
Thoughts? Maybe I went too farfetch'd?
