It couldn't be referring to Schala now, could it? If you do the Black Omen sidequest first and take teh gate inside of Lavos back to the End of Time and talk to Gaspar, he says, and I QUOTE:

"That poor woman can finally rest, now that the Black Omen is gone.

She's reverted back to a human..."

Now, that DEFINITELY can't be Schala since (SPOILER)she merges with a Lavos Spawn to become the Time Devourer; 'tis hardly human!
