Immortality neg via EE

[Quangotjokes]

If a character can erase someone conceptually but in the process absorb their potential to exist. Would that negate their immortality entirely? Instead of just negating the regeneration?

Context: The Devourer can uncreate, beings, concepts, histories and more and make it so that they’ve never existed in the first place. The released potential is absorbed into the uncreator, hence the title “Devourer. Which means the potential they had to return from being erased if they could originally is gone/ absorbed.
