Archean Essence

Archean Essence, also referred to as Divine Spirit, is the name given to the residue remaining following the sacrifice of the Divine Six. There are 6 different Archean Essences, each corresponding to a member of the Divine Six. An Archean Essence is typically reffered to as a gem, however it may take on a number of different forms depending on its environment. Consumption of an Archaen Essence gives the user its respective Kigen, however few survive assimilation.
