The Triune is reported to have first revealed itself during the Age of Magic after the Grrrlf War, appearing to contemplative soldiers at the original Shepherd Garrison in the Harkune Mountains. The Shepherds became priests of the three-faced deity and began to proselytize; the Church of the Triune coalesced into three Arms, one for each Face, providing spiritual and cultural guidance to their adherents. The religion was scoffed at by popular and powerful mages, who saw no need for deities when they had magic.
However, a period of anti-magic Uprisings followed the magical destruction of Chuno which created the Waste, and mages were driven into hiding while the Sisters of Senaedrin, the healing Face, tended to the victims of the violent magical maelstrom and became a powerful factor in the rebuilding of Chunese life.
When Valorian I decided to expand his kingdom into an Empire, he persuaded the priesthood of the Triune that their faith could be more easily spread in a unified and secure territory. The religion is uncontested in Antara.
Though the Triune is represented as a three-part deity, there is some evidence that the three Faces are aspects of one undivided entity.
Senaedrin is the only feminine Face, representing healing, renewal. The Spring Festival, a religious and cultural festival celebrated in the Antaran Empire, marks the time of Senaedrin's annual rebirth, and the first four months of the year are counted as the "months of Senaedrin."
Henne represents childhood, innocence, laughter, and celebration, and is considered the patron of the performing arts. The four summer and autumn months are counted as the Months of Henne.
Artifacts associated with Henne include Henne's Horn.
Kor is perceived as a guardian and a warrior, brave, wise, and fair. The four months of winter, culminating in the Spring Festival and the renewal of the year, are counted as the Months of Kor.
Artifacts associated with Kor include Kor's Blood.
