Understanding Vitiate
It is becoming clear with passage of time that Vitiate is not a living being but an entity. He was a mortal living being during in earlier times but he began to change in the aftermath of Nathema event. He maintained corporeal existence for some time but eventually began to manifest in the form of Children and Voices. He can exist as a disembodied being as well.
So is Valkorion a Voice or something more?
