The Valar announce that they've done as much as they can in Singularity (they can't bring back peoples' babies in that critical period either, but they can get them earlier versions) and are setting up portals between there and Sanity as soon as they are confident they've cleaned up the plague.

"I'm a human being, and if I stopped being a human being I'd be someone else whatever became of my body."
"I mean, I was a human being and then I died and then I was a daeva and I don't feel like I'm someone else."
"Any kind of 'being a different person' that you can't actually notice under any possible circumstance seems meaningless, honestly."
"I didn't say whoever woke up would notice, I said they'd be different."
