The Tapestry of Truth is the inquisitorial arm of the Dhomist religion. They are based out of a fortress in the Basilica of Light in the capital city of the empire. The Edict of True Belief limits the authority of the Tapestry to the borders of the theocracy, but in reality the reach of their agents tends to be greater. Wherever there is humanity, there is the Tapestry.
The singular purpose of the Tapestry is to prevent another catastrophe. They collect magical artifacts to keep them from falling into the wrong hands. And, they hunt down rogue spell casters.
