Zefiroth lived most of his life in the Everfree forest in total anonymity, hiding his physical dragon appearance for a smaller and harmless one, drinking tea and watching his trees grow. His life was very peaceful, he didn’t want recognition or riches… but he had a great thirst for knowledge.

This was how the spirit of the earth became a pet for years.
