Revelations from Patch 5.3

[Hikari_Kishimoto]

Seeing as most (all?) of us are reincarnations of sundered ancients, does that mean Emet will have been shredded up and chucked into the lifestream when he died?
Would he even get sundered at this point?

I'm afraid not. As I understand it, when you pierce an ascians soul with light, it fades out of existence.
It doesn't return to the lifestream, because the soul itself has been destroyed.
