That was reality.
Somewhere separated from the perception of both the living and the dead was the Wheel of Samsara which controlled the reincarnation cycle.
Through it, souls would be returned to their natural state and removed from everything that defined them so they could enter a new body and live again.
Of course, this process wasn't always accurate.
Sometimes, souls would have deeply entrenched desires, regrets, or even memories that would appear in their new lives in some way, shape, or form.
But in the end, even true reincarnation with memories intact was impossible.
This was an absolute rule established at genesis, a concept of a level Universal Law couldn't even compare to.
But Damien…
When his ego was erased, he was gone from the universe completely.
That's how it should've been.
But for some reason, he could see it all.
