Let's take this a step further. Hythlodeus....what is he was Azem, in the same way Hades was Emet-Selch? Azem is just a title. What if Hythlodeus is our unsundered self? Why else would Emet-selch put so much care (and over-attentiveness to detail) in recreating him? ("I may have gotten a bit carried away.") He recreated us. He wanted us to remember. It is also why he recognized the color of our soul (and Ardbert by association). It also explains why he had our stone.....the one created for us by Emet-Selch.

I mean, wouldn't this be possible?
