The Divine Branch are some sort of cult or revolutionary group that worship the goddess Aeltra. They appear to operate mainly in the Tygarl and Hymnethas districts, according to Yuleyan Alexandar. Their goals seems to be the eradication of "devils" in the area, but Yoxxel has accused them of kidnapping wizards, killing guards, and threatening the peace of the kingdom.
Inglis Alexandar is apparently leading the group in some way, hunting a devil known as the Jackal.
