Ancient level warriors were warriors that had awakened and unlocked the power of their souls.
The key to awakening their souls was the provision of two crucial sources of power for the souls.
The first was providing the soul with a soul power structure.
Prior to awakening, the soul was just a lump of spiritual mush, containing the identity of the body, but without form nor power.
The journey towards Ancient level simply refers to the creation of soul power structures that would allow for the soul to wield soul power.
The second would be to fill the soul power structure with soul power. Once the soul was filled with soul power flowing according to the pathways of the soul power structure, then the soul could be truly considered as an awakened soul.
The soul would be able to continue to expand on its power structure and increase the amount of soul power it contains.
