Childhood, youth, adulthood, prime of life, peak, old age—these six stages correspond to the Zeroth Order during childhood.
Youth corresponds to the First Order to Second Order, generally between the ages of fifteen and fifty.
Adulthood is from the Third Order to the Fourth Order; ordinary Tribe warriors should be around sixty to ninety years old to reach this level.
Most Totem Cultivators remain between youth and adulthood, their power fluctuating between the Third Order and Fourth Order until they die of old age.
This is a threshold; Third-Class Totems can only grow to this extent, and only a few with Second-Class Totems can break through the shackles of the body and step into the prime of life.
The prime of life corresponds to the Fifth Order to the Sixth Order, typically around three hundred to eight hundred years old.
