The Andromeda Galaxy
Surrounded by seven planets the bright G type star at the center of the Galaxy shines brightly. It gleams off of the surface of the pristine hot springs of Nevala and moves on bouncing off of the brilliant planet of Starsis. The Sun's rays now move out to the electrified surface of Cirruses dancing among the large skyscrapers onward to Quatis giving life to the plants so needed for the support of life and existence in the galaxy. The beams now bounce into Volsus, spilling into windows of offices and labs where some of the most ingenious minds in the galaxy are hard at work. Now miles upon miles away from the sun barely illuminating the cold desolate ruins of a once great planet known as Xenen. Cities that once stood proud in the faint rays of the far off sun now lay in rubble, no one having set foot on the planet since it was disappeared on it's usual far off course, out of the galaxy into the nearby Milky Way returning to the Andromeda system dead, and utterly desolate, a sign. A signal to the living that the Negaverse was just on the other side, having annihilated every living thing on the planet before it's return.
The Seer Dragons
The seven Seer Dragons, creators of the Andromeda Galaxy. Forging it in light and making each planet within self sufficient yet dependent on the others. Each dragon forged a planet and a race. Luminous the dragon of starlight and energy birthed the Cirrusians. Tempest the dragon of silence and creation birthed the Volsians. Inferno dragon of fire and emotion gave life to the Nevalans. Catalyst the dragon of darkness and destruction created the Celestians. Eyo the dragon of life created the Startisians. Supernal the dragon of spirituality and rebirth gave life to the Quatisians . The dragon Bane, of death and dissolution created the Xenionans. The only dragon without a race to call his own was Tempo The dragon of time and space, thus being because there were not enough planets, and for Tempo couldn't create a race fairly in line with all others being that that the Mystic magic that Tempo wielded, was far more powerful than all others. Tempo then took the purest of hearts under his wing and created the order of the Seers, a group of priests and priestesses that took the text for all of the galaxy.
When the planet Xenen as well as the Xenionans was destroyed on it's trip into the nearby Milky Way Galaxy Bane went rabid with rage, blaming the other dragons for not trying to help, accusing them of allowing the Xenionans to perish. One survived, however, her name was Refla, Bane created a plan of vengeance and with it found the forces of the Negaverse to aid him, creating a dark Prism and turning Refla into a warrior, known first as Sailor Prism, who then had her star seed taken, in order to make her evil. She is now known as Queen Prism. To combat the force of Queen Prism and the dragon Bane the other Seer dragons selected warriors of their own each one from it's chosen planet, and Tempo searched out the purist of heart among the planets.
