So we found out Hayden is part jaguar and the Noah guy was part berserker. I thought berserkers were made by using animal bones and skins to attach the animal spirit to them and they were mindless brutes. Plus the kid was drinking blood, maybe it has something to do with the bones growing out of his arms, like he needed the iron or something.
