The Inquisition was formed at the end of the Blood and Book wars. Their self appointed task was to hunt down and destroy rogue mages and sorcerers chose not to abide by the Ark Treaty.
To this day they continue that duty. They often do not wait for a guilty verdict or even a trial, and of late they have earned a reputation as witch hunters.
There is currently a large contingent of their followers watching the border of the Dark Forest. Local villages have been being raided nightly by goblin bands from the woods. Now their crops are being eaten by the Inquisitors, though they liked to be called Watchers. The real question is, what is pushing the goblins out of their homes?
