"You expect me not only to find a YOUNG EARTH Dragon but to get one of its teeth?"[Ameanum]
Dragons were considered young between their first decade and before their first hundred years of living. Before that, they were considered Wyrmlings; after that, they were Adults. When they reached their first thousand years of life, they were Ancient.
Each time they transitioned between those categories, there were massive boosts on their stats and powers.
An Earth Dragon was one of the artificially created Dragons, as researchers wanted to reproduce the Dragons' power, so they tried to make one using the Elements.
The Earth ones are one with the highest defense, even among real Dragons, but were the most difficult to create. Because the Earth Element mana is the biggest in quantity in the Mortal Realm, the resistance in creating something unnatural like that of such a degree was hundreds, maybe even thousands, of ways more complex than with the rest of the Elements.
