Within the Province of the Nine Skies, far above the heavens, there exists nine galaxies of astral rivers. Each of these astral river is made up of the combination of countless constellations interwoven together. These nine galaxies can also be collectively known as the Nine Layers of Heaven.
Humans of this cultivation-oriented world advocate the importance of meditation as a method to sense the Yuan Qi of Heavens and Earth. From a young age, they would practice breathing techniques, to train the spiritual Qi in their bodies, and to increase their vitality – they would cultivate their martial techniques in order to eventually become a Martial Cultivator.
Those with exceedingly strong senses could, through mediation, sense the existences of the nine astral rivers. By absorbing the energy projected by the boundless array of stars, and after forming an innate link with any of the constellations, condense an Astral Soul, and become a revered Stellar Martial Cultivator.
