Abby's Chaos-
Before Abby there was her mother and father, her heritage, her history, and religion. Before Abby the world began in seventh days that lasted millions of years, and God said "let there be light" and there was light with the explosion of helium and hydrogen and man and woman were bulit from the perfection of the apes over years of evolution.
Jessi's Chaos-
Before Jessi there was her mother and the world. The entire universe around us, from the Phalanx to the Brood to the Shi'Ar, began as a tiny atomic speck that appeared from nothingness and exploded in the Big Bang. It is from this bang that stars came into being and from the stars came the planets, and from the planets, life. Thus, in her own special dreams, all life comes from the deepest heart of a star.
Oreanna's Chaos-
Before Oreanna, there was Krynn, and the ages of Might and Starbirth, but even then a part of her was there in the guise of her creators, the great gods themselves, Paladine, Gilean, and Takhisis. The beginning was formless and uncontrolable when the High God awakened. And he called the three great gods and they called the lesser gods and they all used their essence to form a hammer with which the Reorx forged the Chaos into Krynn. And from the forging came the sparks of stars and sparks of singing spirits. And so life came to Krynn.
Kitty's Chaos-
Before Kitty, the world turned merrily without any notice to the history going on. That's all that happened, and now she'll keep up with her own history, thank you very much.
Jewel's Chaos-
Before Jewel, the powers created all of this, and the ballads sing and poems tell of all the events she happened to have missed in her time. Thus, the past is not Chaos at all, but ancient words on yellowed parchment, colored silk gowns stiff with age and an air of dust, tarnished gold coins of civilizations long past. This is the past before Jewel, and to her, it is all a mystery worthy of the greatest tales.
Kandeda's Chaos-
Before Kandeda, Krynn existed and she heard there had been good times, but she'd never seen any. The older women in the village told her alot about how about 40 years before she was born the world had been destroyed by the gods in some sort of attack on Istar. As for the Planes and the multiverse? It would fry her brain to try and track them before she arrived.
