Guilbert is first encountered during the quest "Separated at Birth", when his brother Reynald Jemane in Chorrol hires the Hero to find out who is impersonating him in Cheydinhal. Upon learning that his brother, whom he believed to be dead along with his mother after their childhood home was sacked by Ogres, still lives, he leaves for Chorrol immediately. Upon arriving in Chorrol, he will meet his brother at The Grey Mare and from then on, Reynald will always refer the Hero to Guilbert.
