Founded by Park Hyo-Sonn after the revelations of her twin brother's crimes, Uiloun Gil is devoted to rooting out demonic corruption and influence within the bounds of Daeyang Province. They take their task very seriously, urging the people to turn on any who might even be suspected. Hyo-Sonn herself regularly leads these investigations and does so with a fervor.
The actions of The Righteous Path seem to have the approval of Duke Unknown.
