Dutiful is the son of Kettricken and Verity, although due to the sickly condition of his body at the time of conception, Verity used the Skill to swap bodies with Fitz in order that an heir be produced for the Farseer throne following the death of their first child, Sacrifice. The slightly ambiguous nature of Dutiful's parantage is not an overly large issue towards the future of the Six Duchies; however, he is undeniably a Farseer whichever father is considered his "true" one. None of this is ever revealed to Dutiful.
Dutiful lives in Regal's former grand chambers in Buckkeep and keeps them simple and ascetic in the tradition of his mother's Mountain Kingdom people. He has dark eyes and curling black hair like Verity, but his jawline, slender body and height are more like those of Fitz's father Chivalry.
It is revealed that Dutiful has the Wit as well as the Skill, something that caused him to be kidnapped by the Piebalds. He was bonded to the Cat for a while, before she was killed by Fitz while she attempted to attack Fitz and take over Dutiful's body. Fitz returned to Buckkeep with him and began to instruct him in both of their shared magics.
Dutiful later married the Narcheska Elliania, after going on a quest she issued (at the Pale Woman's orders) to bring the head of Icefyre, the dragon of Aslevjal to her hearth, which he achieved ‚Äî although due to a certain chain of events it was still attached to his body, causing the loss of her home's door in the process.
