While the ranking system for Mana Cores was drastically different from the ranking system that lay behind Essence crystals, it was much easier to understand.
There was a proper order to follow step by step for the cultivation of a Mana Core and one couldn't really skip the ranks in the tempering process of the Mana Core.
However, Essence Crystals had no such criteria.
The Primordial Ascension's System labeled the Ascenders of the fifth Tier 'Demi Gods', the Ascenders of the sixth Tier 'Lesser Gods', and the Ascenders of the highest Tier 'True Gods'.
Under normal circumstances, one would create the foundation to Godhood at the fifth Tier while being a Demi God. Afterward, one would have to create a faux Divinity so that one could comprehend the hidden world behind the meaning of one's abilities, power, and the purpose of one's life.
