Heretics are Priests of the Arisen, who voluntarily made a vow to serve the Triune Imperial Church. This is the Arisen faction of the holy Church of Light. Being atheists, Heretics study and research the Holy magic that came into this world. They are the most devoted members of the Xadaganian Church in performing rituals, following the vows and penance. They compensate for their lack of faith by sheer endeavour and thoroughness.
