Chapter 327.1
The image of the Inquisitor as an executioner is actually a relatively recent development.
Originally, the role of the Inquisitor was focused on investigating historical records, interpreting doctrine, and acting as prosecutors in religious trials. Their purpose was to identify cults or heretics who distorted doctrine or followers who had been influenced by other faiths.
However, much changed after the Licht Treaty.
The Codex of Light clergy had to lower their lofty gaze and adapt to the new world order. Having relinquished much of their power and authority to the common people, the only domain where they could still exert influence was faith.
And the Inquisitors became an effective weapon.
When the clergy made political decisions, the Inquisitors would find the justification to back them up.
In that process, anyone who stood in their way was labeled a heretic.
It became the role of the Inquisitors to first create the problem and then prove it.
As with any such organization, Inquisitors eventually gained overwhelming authority within the clergy, to the point where they could carry out summary executions if the situation concerned internal matters.
