This mission is fairly straightforward. After a short journey to a village, Justiciar Hablion (A on the map) will tell you to cleanse yourself in a fountain (B on the map), then escort a green hovering eyeball. This eye will "judge" people and reveal any magic they may have. You can determine whether or not villagers are chosen by taking the eye close to them. The eye will also do an knockdown on all foes adjacent to it every few seconds. This can be useful, so make sure to have the eye close to where you're fighting.
