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.

Now they have more stuff. "Oh - you should probably know - people who've summoned daeva become daeva when they die."
