So What is Elidibus Planning (4.56 Spoilers)

[Belhi]

There is a lot of hints and suggestions that the Source is at risk of a Flood of Light. Solas makes a comment on it, Mr Enigma outright says that if we win that is what will happen (which makes sense from what we have heard from Albert) and Elidibus says we have to die to redress the balance. I suspect the thinning Aether is a sign of it as well.

The First has already suffered a Flood of Light though something has stopped it from finishing off the small part that remains. The key for us is that it is on the First that we can learn how to stop a Flood of Light happening which is probably why we become the Warrior of Darkness. The interesting thing is we have Minfilia around as well and as an ally which means we have a representative of the Light and a rep of the Darkness working together. This is how I think we will be able to defeat the Ascians. We will basically steal their role out from under them and usurp their position thus making their involvement no longer necessary.

The curious thing will be how Zodiark works into all this since we are likely going to have to deal with him directly soon.

Mr Enigma outright says that if we win [there will be a Flood of Light]

Even though it's true that he's said we're at risk of causing a Flood of Light if we keep beating Elidibus, that's only half of what he said. "Win or lose, your path leads only to oblivion" - so even if it's dangerous for us to keep beating him, it's not going to be any better if he wins.

I mean, technically, he didn't outright say we'd cause a Flood of Light. It was merely heavily implied.

"Win or lose, your path leads only to oblivion" doesn't necessarily mean "Flood of Light" - Oblivion can mean many things.

For example, I do believe that the "Lose" path is in fact referring to a Calamity. Given that we know that Calamities are caused by the sudden change of light/dark (I still want to know exactly what light and dark are referring to... Is it aspected Aether? Is one low-fat Aether and the other some form of rich Aether? Is Hydaelyn going to at some point remove a mask and be like "Behold, it was me, the Milky Bar Kid all along! I've finally rid the chocolate of all 14 worlds of cocoa beans! Muhahahaha!"?)

The current situation is a high amount of Light, or at least, higher than normal amount. Thus meaning that there is potential for a sudden surge of darkness to then plunge the Source into a Calamity. For example, Black Rose. The death of the Warrior of Light. The sudden expansion of the Garlean Empire retaking control of lost provinces as well as acquiring new ones. Another hail Mary Primal summoning such as Seiryu born from a negative emotion to cause nothing but suffering and death (For example, if someone summoned another shade of Nidhogg)
