Adulthood, old age, and extreme old age are merely terms that describe the age states of a giant dragon.
But at the levels of ancient, ancient ancients and the oldest of the olds, the terms are no longer simply about a giant dragon's age, but are directly related to the passage of time, just as their literal meanings suggest.
No ancient dragon could be younger than eight hundred years old; ancient giant dragons start at a thousand years; ancient ancient dragons are at least twelve hundred years old and have been formidable presences that have dominated the continent for even longer.
If a mere mortal were to live for twelve hundred years, they too would become exceptional, let alone a highly intelligent giant dragon that grows continually with time.
Even without the power to destroy heaven and earth, such beings can't be measured by ordinary standards, having thirty-plus Life Dice or even a great number of Professional Levels is not rare for them.
