Those souls belong to the remnants of past souls that used to inhabit this Supreme Dimension that could not move on and were not completely passed on
Those souls all have ancient aura that seems to have meddled with and they were summoned from the Void of nothingness of this Universe
Some of them look righteous, while some of them have vicious face with a terrifying expression and some looked fearful while some look relieved.
Thousands of emotions and confused memories had melded with the Soul Law Body. And as such all of their memories, their lives were absorbed by the Soul Law Body.
Understanding all the emotions, all the cause and effects of Karma, Destiny and Fate complete the Soul Law Body.
The soul was not absorbed instead of integrating inside the Soul Law Body
The soul is like the life of a person. It is not the Soul Body absorbed these souls. It is these soul that absorbed themselves into Azief Law Body.
