The State Religion of the Great Ri was the state-sponsored syncretic religious system practiced by the imperial family and most of the conquest elite of the Nara Yonggan during their ascendency. The Ri emperors also patronized a variety of other religious faiths, including especially those of the Air Nomad religious tradition and the folk religion of the Earth Kingdom.
At the root of Ri state religion is traditional Yonggan shamanism, as it developed under the pre-dynastic Nara Yonggan khagans. Yonggan religious thought was influenced by cultural contact with the Gan Jin and Abka. By the 1000s BG, it was a henotheistic religion worshiping the heaven-god Abkaiten ("Foundation of Heaven"), which developed into monotheism in which other divinities were interpreted as aspects or persons of Abkaiten. A hierarchal relationship of divine aspects was postulated, with Abkaiten's four coequal chief aspects being Muke, Tuwa, Na, and Edun, the gods of water, fire, earth, and air. The hierarchy goes much farther down, to the level of clan, family, and personal spiritual beings associated with individual humans; mystical thought, considered orthodox since the Shenxing era, extends this hierarchy to include to humans and animals themselves, who are considered themselves (rather humble) members of the divine hierarchy.
Other major influences include the Air Nomad religious tradition, particularly the traditions of the Southern and Eastern Air Temples, and the indigenous religion of the Central Earth Kingdom.
