Blood trolls are an ancient troll subspecies that inhabit the swamp of Nazmir on Zandalar and have been called the "bogeymen" of trolls. They worship the blood god G'huun. Their culture is very harsh and the most primitive troll culture there is, because their god has no need for technology. Their society is also matriarchal; males follow the orders from females without question lest they get chained up and punished or outright sacrificed.
Blood trolls use blood magic. This magic corrupts the creatures around them and turns them into blood beasts.
Their origin is similar to that of sand trolls in the sense that the Great Sundering changed the environment they lived in and they had to adapt.
