Flesheaters
Gray Trees lizardfolk captives of the cult of The Hungerer who were taken to be ritualistically turned into Flesheaters, a vicious zombie-like creature who rends flesh from those they prey on.
The cult and presumably their deity have been dormant for a couple hundred years but have recently been making a comeback. The first signs of their reemergence were found very recently in the swamps near Whitesparrow, where many lizardfolk of the Gray Trees clan who live in the Village of the Swallows were found dead with mysterious symbology carved into their bodies.
