Rise of the Terrans
Characterized by their love of life, music, art, and magic, the Gaia were arguably one of the most fair, and naive peoples in the galaxy. The Gaia were scholars, explorers and philosophers and often times acted as intermediaries and negotiators when conflict arose among the other galactic races. Knowledge and learning seemed to have a direct effect on Gaian physiology, with the most enlightened of Gaia manifesting glowing auras about their heads, sprouting wings, or the ability to shape shift, or manifesting physical aspects of the magics which they had mastered (flaming hair, acompanied by a constant breeze, ect).
It was a Gaia exploration vessel, the Olympus that first discovered the Sol System, and by extension, Earth. Here the Gaia established a presence both for mining and research purposes. It was the Gaia that first attempted to modify the aboriginal species on Earth to use a laborers and the Gaia that eventually succeeded in gifting Terrans with sufficient intellect to be useful. After the Earth wars, it was also the Gaia that bartered the terms of the Atlantis Treaties and later went on to create the Synodos.
Now, the Gaia are all but extinct, with only a handful surviving throughout the universe. The Gaian systems has been over-run by the Synodos who are slowly expanding into other galactic races territories. What caused the Synodos to turn on their masters, we may never know..
