Secret Societies of Chult: The Mage Hunters

Publisher's blurb:

Before the Spellplague, the practice of magic in Chult was presided over by Mezro's College of Wizards, and regulated by the fearsome Mage Hunters. But those days are gone, and the jungles face new, even more dangerous threats.

Once charged with hunting down and stopping renegade spellcasters, this ancient order of wizards are now tasked with protecting the fragile magical balance of Chult from being corrupted by dark, otherworldly threats.
