Kigen

Kigen, or Origin Powers, are Ge that were once wielded by the Divine Six. They are much more powerful than regular Ge but require a significantly greater amount of energy to use. They visually appear the same colour as their Ge when used. They also do not fall under any Class.

A Kigen may only be obtained from consumption of an Archean Essence, or inherited from someone who has consumed an Archean Essence.
