Kos and Loran

I might be going crazy, but hear me out on this theory:

We know that Loran was the first Pthumerian kingdom to fall to the scourge, and it's heavily implied that the Nightmare Frontier is what remains of Loran. From the Frontier, you can also see the Fishing Hamlet.

That got me thinking: what if Kos was originally a woman from Loran who ascended and began sharing her blood with its people? The kingdom eventually fell to the scourge, and when she became pregnant, she was too weak to continue helping them. As a result, she drifted out to sea and eventually washed up near the Fishing Hamlet, leading to the events we know from the story.

I know there's not much evidence for this, but I thought it was an interesting possibility. What do you think?
