Adderjaw was named for his overbite, which his mother noticed before he had any teeth to make such a name fitting. What he lacks in grip, he makes up for with a range of very clear expressions and a slight... offness to his proportions that leaves the rest of his pack wondering what it is about him that makes the boldest among them reluctant to meet his gaze for long.
Regardless, Adderjaw gave the Ring of Briars its name, and for now at least, he has served the pack well.
