Is it even possible for the Ascians to succeed?

That's the closest I can find

Oh, jeez; I guess I could see how that could be read multiple ways. That's gonna come back to haunt me for the rest of the summer, isn't it.

As far as I can tell from the other languages, this is part of the Ascians' sales pitch to her: not that the Thirteenth can be saved, but that she can redeem herself for its fall by rejoining the First. The Ascians are saying that her failure to prevent the Flood of Darkness is why the Thirteenth fell, and because the Thirteenth fell, the shard directly opposite (The First) it is damned to fall to an eventual Flood of Light because the cosmos likes equilibrium. Ergo, they're saying that a Flood of Light befalling the First is in part her fault. The Rejoining would prevent the First from becoming a void, and thus rejoining the First is her redemption. She could be part of preventing the First from becoming a useless "World of Nothing."

The plan was to put the "inevitable" rise of the Light under some semblance of control by setting the stage for a Calamity, beckoning the creation of Warriors of Light whom the Light would gather around. The Shadowkeeper secretly led to this, creating disasters to support their growth while using that influence to create more disasters; on and on the feedback loop turned. When the Light had gathered (tilting all elements umbrally and beginning the diffusion into the Source), she would strike them down, delaying the Flood while the Ascians triggered the Calamity on the Source and broke the membrane between dimensions.

I don't see anything in here that would fix the Thirteenth; does anyone else?
