In the Age of Ten Thousand Beasts, the world is filled with mystery and wonder. When people turn eighteen, they reach a major turning point in their lives: drawing qi into their bodies and awakening their Beast Core!
Drawing qi into the body means people can resonate with the spiritual energy of the natural world and draw it inside themselves. This is a very special ability that can only be attained at a certain age. Once they successfully draw qi into their bodies, people have a chance to awaken their Beast Core.
A Beast Core is a latent power hidden within the human body, connected to the souls of various wild beasts. When the Beast Core awakens, it forms a spirit egg inside the body. Like a seed that holds the promise of life, the egg needs time to be nourished and grow.
After a full thirty-day gestation, the spirit egg gradually hatches into a spirit beast. The beast becomes its master's loyal companion and battle partner, and the two share a close bond.
However, spirit beasts are not all alike. They are divided into different ranks: low, mid, high, and the highest, divine. Each rank has unique abilities and traits, and higher-ranked spirit beasts are often more powerful and rare.
In this Age of Ten Thousand Beasts, people and spirit beasts live together and depend on one another. Together, they explore the world's mysteries and face all kinds of challenges and adventures.
