In the beginning, the Chaos Tree of heaven and earth gave birth to the creatures of yin and yang, the Snow White Jade Rabbit and Three-legged Crow. They received an order from their mother to give her some descendants and thus, as they revolved towards each other at an extreme high speed, the symbol of yin and yang connected and the flower of five colors blossomed.
Out of this flower came the Green Dragon, White Tiger, Vermillion Bird, Black Tortoise, and the twin Yellow Dragon and Kirin. These creatures were the foundation of the world and as they set, the low beings under them began to promulgate.
The Destruction and Creation cycles were set in motion as Wood, Earth, Water, Fire, and Metal interacted with each other. The spiritual qi of heaven and earth enveloped the land and all manner of creatures flourished, from dwarves to elves, to fierce beasts and dragons.
But then came the humans, the last creations but the ones with the most potential. However, their physical weakness was matched by their tendency to give birth to the seven sins: Greed, Lust, Wrath, Envy, Sloth, Pride, and Gluttony. These sins materialized and gave birth to powerful creatures such as the Nine-tailed Kitsune, Succubus, Chimera, Basilisk, Mapinguary, Archangel Fallen Lucifer, and Taotie.
The world was forever changed as the ancient beast summoners emerged, harnessing the power of these creatures to shape the fate of humanity. This was the beginning of the summoner world.
