As for the Iron Bull himself, he now enjoys food, drink, and all of life’s earthly pleasures more than he had expected. Telling himself it is for his role as a Tal-Vashoth, he has let most of his self-imposed restrictions slip. Still, the notion of becoming fully Tal-Vashoth brings back immediate memories of those savage monsters in the jungles of Seheron and the children they had killed.
He insists upon referring to himself as Qunari, a distinction that few in Orlais understand enough to make a point of, and he reports to the Ben-Hassrath with perfect devotion. The letters he sends are his lifeline, the single remaining point of discipline holding back the savagery he hunted for more than a decade until the day he saw it in himself.
