- **Setting and timeline**: A cultivation world centered on the "Tianyu Realm," featuring the Nine Heavens and ancient secret realms. The story takes place in the Third Era, after the "Heavenly Firmament Cataclysm," as ancient seals gradually weaken.
- **The featherfolk**: Bloodline ranks are determined by the colors of their wind and thunder wings: azure, purple, gold, and glazed. Every hundred years, they hold the "Heavenly Feather Rite" to select a divine child. Cultivation centers on refining one's innate feathers, and the highest realm allows one to transform into a Kunpeng.
- **Power system**: There are nine major realms, from the Spirit Awakening Realm to the Tribulation Transcendence Realm. Each realm requires one to pass three heavenly trials. The featherfolk alone possess the "Void Meditation Art," which allows them to commune with their ancestors' spirits, but only those with pure bloodlines can practice it.
