The Inquisitor is a position outside the hierarchy of the Temple which holds great power over other members. In recent years, the position has been left unfilled as it is considered contrary to Temple doctrine. However, it was recently revived by Bishop Neil Lars, who granted the title to Selca Ducani.
An Inquisitor's primary purpose is to seek out and purge heresy within the Temple. They are granted powers beyond the law, allowing them to prosecute anyone they see fit using the Temple's own judicial system. During a heresy trial, the Inquisitor typically acts as the prosecution.
