Forced to the will of the increasingly radicalized Great Advancement, Priest Arther was sent to carry out daily executions of supposed magic users and preach to the enlightenment which will come about when the Great Advancement is achieved.

Leading the party to Virion for a meeting, he left the city after it was safe with his family safe and alive.
