Moons of Fate
Cetra, a people from beyond time yet ever seeking to keep watch over those who can not safe guard themselves. The Cetra were a powerful and wise race when the Great Dragons were first seeding the worlds – spreading across the stars in pursuit of knowledge and meaning. In the end they found their purpose and doom in the form of an unearthed being of great power and danger. In fighting the demon Jenova the entire species was wiped from the stars, but the Cetra were not truly gone. A mere ghost, literally, of their former selves – the Cetra exists within the souls of the planets they died upon all those eons ago. When a person is born with a clean soul and a dark cloud hangs over the future like a vile miasma – the Cetra come and fight back the darkness till the chill of death grips them and they again sink into the lifestream.
The other races know nothing of Cetra, and in fact, their rise is so rare and so obscured by the chaos that heralds their coming it is no surprise. Cetra are old souls with the hazy knowledge of a dozen lifetimes – respect should be shown for these selfless saviors and the torments they must endure for our continued survival.
